This metropolitan zone (the Metropolitan Zone of the Valley of Mexico, known as the ZMVM for its initials in Spanish), is formed by the Federal District which is the capital of the Republic of Mexico together with 18 surrounding municipalities from the state of Mexico. The ZMVM is located in a valley surrounded by mountains at 2240 m. altitude. It has a warm climate throughout the year with monthly average temperatures between 12 and 18 degrees centigrade. The average monthly relative humidity is between 50 and 67 percent. Each of the two Federal Entities involved (the Federal District and the State of Mexico) have autonomous control of their own emissions programs. A Metropolitan Ambient Commission (CAM) was formed to coordinate actions between them but does not have any direct overall control at the operational level and because of this, important practical differences exist between ostensibly identical programs in force in the same emissions catchment area. Ozone This high altitude ( approximately 50% higher than Denver Co) gives Mexico City a higher incidence of ultraviolet radiation which, when combined with hydrocarbon and NOx ambient emissions, excentuates the formation of ozone. The problem is enhanced by the fact that the City is located in a valley surrounding by mountains causing sufficient air stagnation for the thermal inversions to be a problem particularly in the winter months. Also, throughout the year, there are often not sufficient ground level prevailing winds to blow the contamination generated within the city, elsewhere. During the 1980s it was appreciated by some that ozone would become a major problem and that vehicular emissions control would be required to maintain a satisfactory air quality. 1. The Mexican Automotive Industry During the 1970s and previous decades, the national policy had been towards developing a self-sustaining industrial base in the country. The automotive industry, whose industrial importance cannot be overestimated, was legislated into increasing national integration by sourcing locally their component needs and eliminating imports both of components and finished vehicles. This industrial policy played an important part in building the industrial base that Mexico today enjoys, but it can be argued that the volume of vehicles that were built and sold in Mexico was not sufficient to justify this policy. As a result, the automotive industry became uncompetitive on a worldwide level and the incorporation of new technology was delayed. 100% CHRYSLER 90% FORD GM 80% HONDA NISSAN 70% VW 60% 50% 40% 30% 20% 10% 0% 90 91 92 93 94 95 96 97 98 99 Exports as Percentage of Mexican Production The opening of the economy culminating in the Free Trade Agreements, however has changed drastically this situation resulting in the majority of the Auto Manufacturers producing more vehicles for export than for local consumption. 100% 80% CHRYSLER 60% FORD GM HONDA NISSAN 40% VW 20% 0% 90 91 92 93 94 95 96 97 98 99 Percentage of All Exports to USA & Canada The majority of the Auto Manufacturers are currently exporting principally to North America where strict emissions control legislation and vehicle emissions warranties exist.

Obligatory Cat Converter change for 94 & 95 model year vehicles 4. 1982 In 1982, a voluntary inspection program was initiated, operated by the Mexico City government's own test centers, measuring hydrocarbons and carbon monoxide. 5. 1988 During 1988, a law was passed requiring an annual emissions check for all vehicles of 1982 and previous model years. This emissions verification was conducted in test centers operated by the city government and in independent test and repair garages. The equipment and static test procedures used met the BAR'84 (California Air Resources Board Bureau of Automotive Repair 3 gas) standard. It was soon appreciated that since this equipment was of manual operation requiring the test technicians to read the instruments and write the result on the inspection report, often the reported figure bore no relationship whatsoever to the instrument readings. 6. 1992 This same problem in California led to the development of the BAR'90 specification in which computerized equipment automatically generated the test reports hence eliminating this source of error. This specification was finally adopted in Mexico City in 1992 when a static test procedure measuring 4 gases was implemented to check the emissions from all the vehicles circulating in the city on an annual basis. Concurrently, a bid proposal had been generated in 1991 to create independent multi-lane test-only "Macro-centers" in which some of the lanes would be equipped with dynamometers to allow dynamic loaded-mode testing. The dynamometers had originally been specified to allow testing of those vehicles with catalytic converters but this was re-evaluated. It did not seem to make much sense to focus the highest emissions control investment on the cleanest vehicles and thus the dynamic dynamometer tests were instead used to verify the emissions from the intensive usage vehicles since these were arguably the highest contributors to the emissions inventory. Other lanes in the Macrocenters where equipped with BAR'90 static test equipment to cover the remaining vehicles. 7. 1993 These centers were in full time operations during 1993. At the same time, strong lobbying by the independent garages forced the city government to close their own test centers. During 1993, 500 Test & Repair centers (with six makes of BAR'90 style equipment) and 24 Macro-centers (with three makes of equipment) were operating in the city. The macro centers each had 5 or more test lanes and were privately operated by different industrial groups, each with several centers. All private vehicles were subject to a 2 speed static test procedure (Low Idle and at 2500 rpm.). The intensive usage vehicles, principally being those owned by companies, were subjected to a low idle static test followed by a road load 40 kph dynamometer test. The load applied equated to 3.5 bhp for 4 cylinder, 7.6 bhp for 6 cylinder and 9.6 bhp for 8 cylinder engined vehicles. This side-by-side operation allowed a direct comparison to be made between the test and repair garages and the test-only Macrocenters. Both had distinct advantages. Test & Repair vs. Testonly Centers The test and repair garages were by far the most convenient for the vehicle owners in that they eliminated the Ping-Pong effect. Most vehicle owners took their vehicles to the garage for a tune-up and to get through the emissions test allowing a one-stop solution to this requirement. They were not caught between a garage that argued that they had correctly repaired and tuned-up the vehicle and the Macro-center that reported the vehicle out of limits. Because of this, most private vehicles went to the test and repair garages whilst the intensive usage vehicles had to go to the Macrocenters for the dynamometer test. None of the test and repair garages where equipped with dynamometers. The test and repair garages were also more convenient to the equipment manufacturers because their utilization factor was lower requiring a higher number of test units to be installed. On the other hand, the test-only Macrocenters were far easier for the government inspectors to supervise and allowed better technical and administrative control to be enforced. Since these centers were concentrated in few industrial groups specializing in emissions verification, they facilitated the adoption of new technology and generated more uniform results between centers. Over time, the results from the test and repair centers degenerated. The garages were obliged to return the vehicles to their owner with the corresponding emissions approval certificate attached and many soon found that they could cut back on the cost of the repair services performed if they cheated on the emissions test. Hence whilst the test and repair garages were very convenient to the end-user their impact on reducing emissions was considerably less than the test-only centers. It finally got to stage where an estimated 50 percent of the vehicles that went through the test and repair centers obtained their approval certificate fraudulently. The public opinion was of a highly faulted emissions control program - which got very close to being shut down permanently at this time. This led to the program being totally restructured during 1995 with major changes being enforced as of January 1996. 8. 1996 At this time, despite the political implications, the licenses were withdrawn from all the 600 test and repair centers. The number of test-only Macrocenters was increased from the then current 26 to 33 having between them, 180 test lanes. A series of stringent quantity assurance controls and technical changes were added to the multilane center operation and a new public identity was generated repositioning them as test-only "Verificenters". The Verificenter Program The main changes that were applied and enforced were as follows: 1) A dynamometer test applying road load at 40 kph followed by a low idle static test was applied to all light duty vehicles (both private and intensive usage). Heavy-duty vehicles, because their size and weight considerations were not dynamometer tested and were subjected to the 2 speed static test as in BAR'90. Whilst in BAR'90 the low idle static test occurs before the high idle test, here the procedure was reversed. It was found that since the vehicle engine's operation at low idle is intrinsically more unstable, that statistically more relevant data was obtained if this stage occurred after the previous warm-up stage at 2500 rpm or on the dynamometer. 2) A centralized operation in each test center was required with "blind" test lanes. The test results, which had previously been available to the tester in the test lane were now only available at the exit station from the center. This required rewriting much of the software to network the systems connecting a data entry station in each test lane to each physical test station, via centralized databases and computers controlling the lanes and printing the reports at the exit from the Verificenter. 3) Electronic security was added via specific access codes for each operational function and checksum algorithms protecting all registers. These measures were designed to restrict tampering of the test results by the personal in the Verificenter. 4) Additional technical and administrative audits were also structured for all test centers, some by government inspectors and others by independent certification authorities and ecological groups. 5) Gas calibration audits were required on each test lane every 30 days. These audits had to be performed by independent accredited materials standard laboratories using EPA protocol 1% certified gas traceable to NIST. 6) Permanent government inspectors were installed in each test Center for the following two-year period. 7) Video cameras were installed monitoring the operation in each test lane of each test Center. This allowed real-time video auditing by the government directly from its ecology offices and continuous 24-hour video recording of the test area. These recordings had to be handed in by the center to ecology on a weekly basis. 8) Vehicle monitoring systems were also installed in all centers generating real-time information and alarms on the number of vehicles entering and leaving each test lane and each center. The systems monitored the time each vehicle remained in the test position. This information was monitored by the government directly from its ecology offices and was also used to generate waiting time information for the general public which is displayed on an electronic scoreboard at the entrance to each Verificenter. 9) Rigid recording and reporting rules were enforced for the general operation of each center and for all incidents in the center. ISO 9000 certification was made a requirement for all test centers. As a result of these actions, the quality of the emissions tests improved substantially. During the second semester of 1995, the test and repair centers reported a reject rate of 5.8 percent whilst the macro centers reported to reject rate of 10.3 percent. During the first semester of 1996, under these new operating rules, the reject percentage from the Verificenters in Mexico City rose 22.5 percent1. The "DaywithoutaCar" Program At the same time, (first semester of 1996) major changes were made in the program affecting the type of certificates that were issued to the vehicles. Mexico City initiated a "day without a car" program which was originally defined to limit the vehicle emissions during the winter months only. As has been previously mentioned, the Valley of Mexico suffered from severe thermal inversions during the winter months when the highest concentrations of ozone are measured at street level. Data available at that time showed the highest ozone levels to occur between October and March each year. Of the precursors to ozone, 71.5 percent by weight of the NOx was originated by transport vehicles and 54.1 percent by weight of the HC was originated by the same source2. To combat this, it was decided to limit the operation of all the vehicles in the ZMVM during the winter months, by one day a week. During an emissions contingency, (defined as when the air quality index was over three times the internationally accepted standard) only the cleanest vehicles would be allowed to operate. Hence, different certificates were issued to the vehicles, through a mixture of emissions and technology level, each with a different and highly visible windscreen sticker. Certificate ONE, was issued to those vehicles that: met stricter emissions levels and had fuel injection and 1 DGCA: 1996 2 Proaire: 1995 data had license plates from the Federal District or from the state of Mexico. This limited the vehicle's operation by one day per week according to its license plate termination. Certificate TWO was issued to all the vehicles that met the normal emissions limits but did not meet the other conditions. These vehicles were also subject to one day without a car per week plus they were not able to operate on the days that were declared to be ambient contingency days. All the vehicles had to get through the emissions tests. The program did not contemplate any waiver for those vehicles that failed their emissions tests or where the cost of repair was above a certain figure hence the only options that the vehicle owner had was to get through the test or to not use his vehicle in the ZMVM. The windshield stickers were very effective in controlling this since they were readily visible to any policeman on duty and the fine imposed for operating a vehicle without an emissions sticker was sufficiently high to maintain the police force's interest in looking out for offenders. All traffic police were empowered to stop those vehicles without stickers. There was a high level of acceptance amongst the general public for this measure to control the vehicle emissions during the winter months, but before the winter season was over, the Mexico City Mayor decreed the program as permanent causing the general level of acceptance to take a nosedive. Twenty-four percent of the journeys within the ZMVM were by private car3 and whilst most people were willing to make an extra effort to live without their car one day a week during the winter months, they were not so willing to do it on a permanent basis. The public transport system in the city was crowded, insufficient and in many ways deficient. The solution that many families adopted was to buy an additional older vehicle ensuring that the license plates termination on each of their vehicles restricted their movement to different days of the week. Hence, this measure to restrict the use of vehicles ended up by causing an increase in the number of vehicles in the city nullifying to a great extent the positive results expected. Those families that obtained an additional vehicle, were forced to use this older and more contaminating car on those days that their cleaner and newer car could not circulate. It also modified the traffic patterns particularly at weekends when all vehicles were allowed to circulate, providing that an emissions contingency was not enforced. Here, each family member could drive a different car and Saturdays became one of the most intense traffic days of the week. 9. 1997 To partially solve this problem, for the first semester of 1997 a third certificate type was added. The certificate ZERO allowed vehicles to operate on all the days of the week. The certificates ZERO was issued to those vehicles that: met the most stringent emissions limits were of model year 1993 or later were fitted with a OEM catalytic converter had a fuel injection 3 INEGI: 1994 had a gross vehicle weight of less than 2727 kgs. had license plates from the Federal District or from the state of Mexico. This measure allowed the newer cars to be used every day of the week and effectively limited the "day without a car" program to those cars of pre-1993 model years plus vehicles of higher gross vehicle weights (particularly SUVs and pickups). The newer model year cars that did not obtained the zero certificates because of their emissions levels or more importantly because they had out-of-state plates were also restricted. Since its implementation, the difference between the certificate ONE and certificate TWO has gradually dropped due to there being less and less emissions contingency days. Although the two types of certificates are still handled separately there is now little effective difference between them. Distribution by Type of Certificate During the first semester of 1997, twenty-four percent of private cars obtained the ZERO certificate, 20 percent obtained the certificate ONE and 56 percent obtained the TWO. For intensive usage vehicles the percentages are slightly different with 26 percent obtaining the ZERO, 18 percent the ONE and 56 percent the certificate TWO. For these two types of vehicle, 22 percent and 21 percent rejects were recorded respectively4. False Passes With these measures, it was estimated that during the first semester of 1997, 73 percent of all vehicles obtained their emissions certificates correctly. It was estimated that eight percent of vehicles obtained a false approval due to incorrect practices in the test process in the Verificenter and that an additional 19 percent of vehicles obtained their certificate through incorrect practices by the garage that tuned the vehicle prior to the test. Here, tuning the vehicle "Late and lean" became a common practice and the vehicle would be re-tuned having passed the test. Whilst these percentages may seem high, they compare very favorably with the more than 50 percent figure from the test and repair centers. Whilst great strides have been made in improving the quality of the emissions control program, there was still several areas that needed to be attacked to resolve problems. Principal Remaining Problems 1) The elimination of the test and repair centers caused a major bottleneck in the remaining Verificenter test lanes. This was particularly evident at the end of each month when extremely long queues were formed of irate vehicle owners looking to get a test during the last few days of their assigned time-slot. 2) The test protocol that is being used applied a road load to the vehicle via the dynamometer at 40 kph for 30 seconds and then a second stage of no-load at low idle for 30 seconds. This was not sufficient to warm up and ignite the catalytic converter on a lot of vehicles and as such could not detect if the catalytic converter was working. 4 DGCA 1 Semester 1997 It was easy to circumvent the test by tuning "lean and late" and/or by other methods. Since NOx was not being measured, there was not any element of control de restrict this. The use of NOx measurement as an element of control is independent of the need to measure it due to its importance as a critical precursor for ozone. 3) The test protocol did not generated sufficiently stable or repetitive test results or with sufficiently low measurement uncertainties to allow its use with the new lower limits that were to be enforced. Increasing installed test capacity. The installed capacity problem was solved by a new bid proposal which increased the total number of Verificenters to 76 with an authorization to operate 337 test lanes. These started operating during 1997 and brought the installed capacity to approximately three times the vehicle population. This number of test lanes was that which probably best maintained the balance between the quality of service to the end-user (i.e. waiting time) and center profitability. If there are too few centers, the profitability of each center is very high because it will be working closer to its installed capacity but the appreciation of the general public is low because of poor quality of service. This is particularly true at the end of the month due to the well-known Mexican trait of doing everything at the last moment. If there are too many centers then the waiting time will usually be negligible as well as the return on investment for the center. This puts a strong pressure on each center to behave unethically if by doing so will improve its profitability. This is especially true for those centers that have to pay back bank loans at the prevalent high interest rates. As a result some centers modified their operational procedures to attract more clients. This involved not charging for rejects, turning a blind eye to visual inspection failures and in some cases getting vehicles falsely through the test procedure. When there were few centers, the companies were so highly profitable that they were willing to police themselves to ensure that they did not lose the opportunity of remaining in this excellent business. When there are many centers, the quality of service increases dramatically but so does the requirement for government supervision. Unless the extent and sophistication of that supervision increases proportionately to the total number of centers, their effectiveness in controlling and reducing emissions will suffer. This became more than evident when the state of Mexico, during 1998 authorized additional Verificenters and test lanes, many of which surrounded the Federal District. By 1999, the two federal entities had between them 154 Verificenters operating a total of 572 test lanes. The two entities involved did not share a common balanced determination to maintain high standards in the emissions verification program causing an important number of vehicles to escape from the test program. At the same time, during 1998 and 1999, in a move to reduce the public's perception of corruption among the police force, the traffic police were forbidden from detaining vehicles because of Verification Sticker violations ­ this being an exclusive faculty of the Ecological police ­ of reduced number. As a result, it became feasible to drive around the city without a sticker on the windshield without being pestered. Missing Vehicles 250,000 Class 3 Pickup 200,000 Van/Wgn Cars 150,000 100,000 50,000 0 to 60 61-65 66-70 71-75 76-80 81-85 86-90 91-95 96-99 Missing vehicles in second semester of 1999 In 1997, those vehicles with Federal District license plates had to verify in the Federal District. This restriction was later eliminated allowing the vehicle owner to choose in which Federal Entity to test. Due to the lack of centralized operational control of the two programs, this added flexibility caused control to be lost. Between the first semester of 1997 and the second semester of 1999, approximately 500,000 vehicles that should have been tested apparently disappeared from the program. 20% 19% 18% 17% 16% 15% 14% Cars Van/Wgn Pickup Class 3 Percent missing in second semester of 1999 This represents 16.8 percent of the vehicle population. It can be expected that the vehicles that disappeared were principally those that would have had difficulty in passing their corresponding emissions test requirements. Of these, the 1981-85 model year range was the most affected with approximately 158,000 cars, 20,000 vans/wagons, 31,000 pickups and 5000 Class 3 vehicles disappearing from the program. Technical Improvements To address the technical problems, during 1995- 96 considerable work was done by the Mexico City government to define a new protocol from which a hybrid version went into effect for the second semester of 1997. The new protocol consisted of an Acceleration Simulation Mode test (known as CAM 97) whose objectives were: 1. to generate more repeatable test results 2. to reduce the measurement uncertainties 3. to permit the use of stricter test limits 4. and to reduce False Approvals CAM'97 The CAM 97 protocol has the following elements in common with the BAR 97 specification: both measure HC, CO, CO2, O2 and NOx both use zero air to calibrate the measuring instruments both require daily calibration of the dynamometer and the measuring instruments both have similar test protocols both contemplate the electronic transmission of data both use bar code readers and both include a training module The principal differences between the CAM 97 protocol and the BAR 97 protocol are as follows: the CAM 97 protocol is for multi-lane operation designed for test-only centers with multiple test lanes where BAR 97 was designed for independent Test and Repair type centers the CAM 97 protocol is designed for high productivity test lanes with up to 150 tests per lane per day with centralized administration and printing in the test Center (vs. BAR average of 45). the CAM 97 protocol does not require a open communications link with the government center for each test. It is structured to have the information of the vehicle population installed in each center via CD and to generate database files with electronic signatures in each register which are later transmitted to Ecology. The Reject/Approval decision is made by the computer in the test center, not by the computer in the government offices. Because of this, the CAM97 specification has multiple access levels and privileges and many additional security checks and balances than are included in BAR97. The use of loaded-mode constant speed testing (Acceleration Simulated Mode) had been proven to be accessible in investment and cost with over 15 million test having been conducted in Mexico before 1997. It allows repeatable measurements to be made with acceptable measurement errors. Whilst this test specification measures exhaust gas concentrations (in ppm or percent) it was designed to be updated to mass flow measurement (grams/ km) at a later date. CAM Test Protocol The dynamic test procedure adopted has the vehicle operating in two stages. The first stage, at 24 kph, applies a load to the vehicle that equates to 50 percent of the maximum acceleration rate that the vehicle has in the FTS 75 test procedure. This is the same as the ASM5015 test procedure. The vehicle then accelerates to 40 kph where road load is applied for a total of 70 seconds. Here, the CAM97 procedure applies 15.5 percent less load than that in California. This overcomes the problem that is found in BAR97 with similar loading being applied to the engine under both operating conditions. Although the same load is applied during the first stage of the test as in California, in real terms, for the majority of vehicles, this results in up to 23 percent more relative load to the engine due to the altitude reducing its effective total power output. During the 24 kph section of the test between 8 and 24 bhp are applied to the dynamometer according to the vehicles weight. In the 40 kph section of the test, for those vehicles with 4 cylinder engines, 3.5 bhp is applied to the dynamometer. 6 cylinder engined vehicles have 7.6 bhp applied and 8 cylinder vehicles have 9.6 bph applied. The combined effect was to increase the range of evaluation to an engine torque relationship of up to 4:1. During the second semester 1997 a hybrid test was instigated which combined these two stages with the previous test where the vehicle certification was conducted as before but with information being gathered for statistical purposes from the new sections of the protocol. Measurement Uncertainties With the change in test procedures and test equipment mandated by the CAM 97 specification the measurement uncertainties involved in the gas measurement were substantially reduced. HC Measurement uncertainties against a measurement of 100 ppm BAR'90 CAM'97 Residuales: < 25 ppm Residuales: < 7 ppm Bench: < 12 ppm Bench: < 4 ppm Cal Gas: < 2 ppm Cal Gas: < 2 ppm Total: < 39 ppm Total: < 13 ppm 39% of the Reading 13% of the Reading For HC, if we look at the strictest emissions limits that are applied, of 100 ppm, the measurement uncertainties with the previous equipment and specifications was 39 percent and by going to CAM 97 these were reduced to 13 percent. CO Measurement uncertainties against a measurement of 1.00 % BAR'90 CAM'97 Background: < 0.02 % Background: < 0.02 % Bench: < 0.06 % Bench: < 0.03 % Cal Gas: < 0.02 % Cal Gas: < 0.02 % Total: < 0.10 % Total: < 0.07 % 10% of the Reading 7% of the Reading For CO, the strictest limits that were being applied was one percent and under these conditions the measurement uncertainties with the previous equipment and test specifications was 10 percent and this was reduced to 7 percent. NOx Measurement uncertainties against a measurement of 500 ppm BAR'90 CAM'97 Background: < 25 ppm Background: < 25 ppm Cell: < 32 ppm Cell: < 25 ppm Cal Gas: < 10 ppm Cal Gas: < 10 ppm Total: < 67 ppm Total: < 60 ppm 13.4% of the Reading 12% of the Reading For NOx, looking at a reading of 500 ppm, the tolerances with the new equipment specification was set to 12 percent. however, to this must be added an uncertainty of 13.3% in the load and speed applied by a correctly calibrated and maintained dynamometer (3% for torque and 10% for speed) This protocol was finally fully adopted with its corresponding emissions limits in the first semester of 1999. At this time, the nitrous oxide emissions were not used as a cause of rejection. This was later introduced in the first semester of 2000. The new extended test protocol was benign for the majority of vehicles resulting in lower emissions readings from the same vehicle vs. the previous procedure. As an example, for those vehicles of up to 1985 model year and of less than 2727 kgs Gross Vehicle Weight, where the previous test procedure had a limit of 350 ppm HC and 3.5 percent CO, with the CAM 97 test procedure, equivalent limits giving the same reject rate, would be of the order of 270 ppm HC, 3.0 percent CO, and 1500 ppm of NOx. For those vehicles of the same GVW but of the 1986-90 model year range where the traditional limits applied were 300 ppm HC and 3.0 percent of CO, a similar reject rate would be obtained with the CAM 97 test procedure against limits of 220 ppm HC and 2.5 percent CO combined with a limit of 1500 ppm NOx. 10. 1999 Emission Limits As a reflection of this, new emissions limits were published for the first semester of 1999 simplifying in the model year range is and reducing the maximum values. The following graphs illustrate the limit development process over the years. It can be appreciated that as an incentive to remove older vehicles from the population, the current mandatory established emission limits are at a level that were not met by many of these vehicles when they were new. This tends to push these vehicles out of the ZMVM and into the rest of the country. 800 up to 1979 1980-86 700 1987-90 1991-93 600 1994 and on Cert ONE 500 Cert ZERO 400 300 200 100 0 1994 1995 1996 Jul-96 1997 1998 1999 2000 HC Limits for light vehicles In 1999, a maximum HC limit of 300 ppm was established for all vehicles of less than 2727 kgs GVW up to the 1990 model year with a limit of 200 ppm for newer vehicles. To exempt from the day without a car program the vehicle had to meets had to be within a limit of 100 ppm HC. 7.00 up to 1979 1980-86 6.00 1987-90 1991-93 1994 and on 5.00 Cert ONE Cert ZERO 4.00 3.00 2.00 1.00 0.00 1994 1995 1996 Jul-96 1997 1998 1999 2000 CO Limits for light vehicles For the same vehicles, the CO limit was set for 1999 at 3.0 percent for vehicles of up to the 1990 model year and 2.0 percent thereafter. Being within a 1.0 percent limit was a requisite for exempting the day without a car program 800 1979 y anteriores 1980-1985 700 1986-1991 1992-1993 1994 y posteriores 600 Cert ONE Cert ZERO 500 400 300 200 100 0 1994 1995 1996 Jul-96 1997 1998 1999 2000 HC Limits for medium vehicles For vehicles of over 2727 kgs GVW, a limit of 350 ppm HC was established in 1999 for up to the 1993 model year and 200 ppm thereafter. The exemption level for the day without a car program was also set to 100 ppm. 7.00 1979 y anteriores 1980-1985 1986-1991 6.00 1992-1993 1994 y posteriores 5.00 Cert ONE Cert ZERO 4.00 3.00 2.00 1.00 0.00 1994 1995 1996 Jul-96 1997 1998 1999 2000 CO Limits for medium vehicles As far as CO is concerned, a limit of 3.0 percent was established in 1999 for up to the 1993 model year and 2.0 percent thereafter. A target of 1.0 percent was again established to exempt the day without a car program. Catalytic Converter Replacement During the first semester of 1999, a voluntary program was established to replace the catalytic converters on the 1993 model year vehicles. The change in catalytic converters was only obligatory for those vehicles that had NOx emissions > 800 ppm. During the course of this program, it was seen that the 800 ppm level was unrealistically low and this figure was increased to 1200 ppm. During the second semester 1999, all 1993 model year vehicles where required to change the catalytic converters independantly of the emissions reading obtained in the test. 11. 2000 During the first semester of 2000, this program of the catalytic converter renewal was made obligatory for the 1994 model year cars and in the second semester of 2000 for the 1995 model year as well. The emissions results shown in the corresponding section of this report would not seem to justify the changes for the 94-95 model year vehicles. NOx Limits During the first semester of 2000, NOx limits were finally established for all vehicles. To obtain a certificate ZERO the vehicle has to generate less than 1200 ppm of NOx. To obtain a certificate ONE up to 1500 ppm of NOx is allowed and to obtain a certificate TWO up to 2500 ppm NOx emissions are permissible. Having established these limits, it was discovered that they were causing unnecessary hardship to a number of vehicles, not allowing them to obtain the desired certificate, and as a result, the government decided to reduce the dynamometer load that is applied to the vehicle during the 24 kph stage of the test on 481 different vehicle types. 300 250 200 150 100 50 0 0-14.9 15-19.9 20 - 24.9 25 - 29.9 30-34.9 35 on Percent Load Reduction Applied at 24 kph by Number of Vehicles Affected The applied reduction was between 8 and 53 percent (average reduction 24.4 percent) of the previous CAM 5024 (ASM5015) figure allowing them to reduce the NOx concentration from these vehicles without affecting the published limits. 5.

Since the mid-1970s, the sale of new gasoline vehicles in the Republic of Mexico has been very volatile, caused by major fluctuations in the economy that often appear to have been related to the six-year presidential cycle. As an example, in 1994, 597,602 gasoline vehicles were sold in the Republic of Mexico. However, the "Error of December" in December 1994 caused an economic crisis in the country that resulted in total vehicle sales in 1995 of only 184,810, this being only 31 percent of the previous years total. Other factors have also influenced vehicle sales over the years. Between 1986 and 1991, the sale of class 5 and 7 vehicles with gasoline engines was prohibited in Mexico. This governmental action was intended to favor state owned companies. These pronounced fluctuations in new vehicle sales obviously impact the way the vehicle population in Mexico is conformed.

Over the period of 1996 to 1999, 4 cylinder engines accounted for 66.5 percent, 6 cylinder engines for 15.8 percent, and 8 cylinder engines for 17.7 percent of the total of 2,151,677 vehicles that was sold in the Republic of Mexico during this period. This increase has occurred principally in cars, and to a lesser extent in pickups. Whilst class 3 and gasoline powered class 7, still use exclusively 8 cylinder engines, the segment of vans and wagons has changed dramatically from, historically, 4 cylinder engines to 6 and 8 cylinder versions with the introduction of Sports Utility Vehicles. 13.

Up until 1984, no vehicles had been sold in Mexico with catalytic converters. As of this year, some imported vehicles were introduced with catalytic converters. They were ineffective due to the complete lack of lead free gasoline in the country. During the period of 1991-1995, 2. 6 million vehicles that was sold into the Republic of Mexico, 570,000 had no catalytic converter, 175,000 had 2 way converters, these vehicles were carburated. 238,000 vehicles had three way open loop systems, (also carburated) and the remaining 1.7 million vehicles had three way closed loop catalytic converters. From 1996 to date, all new vehicles sold into the national market have been equipped with three way closed loop converters except a limited number of heavy vehicles, principally Ford, whose sales were authorized without a converter exclusively for use with LPG and natural gas. 14.

The remainder are exported. For Chrysler and Ford, the Mexican market accounts for only 10-20 percent of their total production in this country. 16.

The previous two graphs, when analyzed together, show, without any doubt, the logistical advantages to the vehicle manufacturers of incorporating technological changes in those vehicles destined for the Mexican Market simultaneously with their export program.

Of these 4,617,757 are cars (62.6 percent), 1,555,614 are pickups (21.1 percent), 639,950 are vans or wagons (8.7 percent), 477,929 are class 3 vehicles (6.5 percent), and 87,887 are class 5 & 7 vehicles (1.2 percent). Considering that the total population in 1985 was 4,657,949 gasoline powered vehicles, this represents an average growth rate of 3.1 percent per year. Over this 15 year period, cars have gone from 65.1 percent to 62.6 percent of the total population whilst pickups have gone from 19.7 percent to 21.1 percent. The number of class 3 vehicles in this population has gone from 4.9 percent in 1985 to 1.2 percent in 1999 with a similar tendency being shown by class 5 & 7 vehicles going from 4.9 percent to 1.2 percent. The number of vans and wagons has increased however going from 4.1 percent of the total population in 1985 to 8.7 percent of the population by the end of 1999. Grupo Trafalgar SC 18.

This national population, as of December 1999, of diesel vehicles is split as follows: There are 93,100 class 6 & 7 trucks at the national level of which 19 percent are based in the ZMVM (14,970 units). These trucks are mainly for pickup and delivery or short haul operations. The class 8 truck fleet consists of 33,190 rigid trucks and 75,373 tractor units on the national level. 40.5 percent of the rigid class eight trucks were bought in the ZMVM geographical area. 34 .2 percent of the class eight tractor units were also bought in this geographical area. This accounts for 9,560 and 19,200 units respectively. In the class 6 & 7 bus fleet, at the national level there are 28,980 diesel engined units of which 15.8 percent were bought in the ZMVM geographical area. This accounts for 3951 vehicles. In the Republic of Mexico there are 22,270 long distance, Greyhound style, coaches. It is not possible, with the data on hand, to proportion these to different cities in the country because of the type of operation and routs that these vehicles cover. As far as we are aware no reliable data has been generated for long haul vehicles (trucks or coaches) on how much time is spent or distance covered by them in metropolitan areas. This information would be useful to determine the effect that these vehicles have on the local urban air quantity. Grupo Trafalgar SC 19.

Of these in 1999, 2,183,256 are cars, 369,122 are pickups, 245,400 are vans or wagons, 153,503 are class 3 vehicles, and 40,990 are class 5 & 7 gasoline powered vehicles. 100% 90% 80% 70% 60% Class 7 Class 3 50% Pickup 40% VanWgn Cars 30% 20% 10% 0% 85 87 89 91 93 95 97 99 ZMVM Population from 1985 to 1999 The participation of each type of vehicle in the Mexico City metropolitan area population over a 15 year period has been basically constant with the exception of vans and wagons whose participation has increased from 5.2 percent in 1985 to 8.2 percent in 1999 with a corresponding decrease in class 3 and class 5 & 7 vehicles. Class 5 & 7 vehicles represented 4.8 percent of the total population in 1985 and by 1999 in this figure has been reduced to 1.4 percent. These vehicles have been substituted by similar or heavier Grupo Trafalgar SC vehicles with diesel engines and as such do not figure in this gasoline powered vehicle population. 21.

This represents 170,678 vehicles out of the total population of 245,400 vans and wagons at the end of 1999. The remaining 30 percent of this population is principally of model years 1971 - 1990. The population of 1996 to 1999 model years accounts for 36.3 percent of the total van / wagon Mexico City population. Grupo Trafalgar SC 24.

Of these, 53.4 percent are of 1991 or more recent model years but only 84,831 (23.4 %) are of 1996 or more recent vintage. Whilst pickups and van / wagons have a similar number of vehicles in the population of 1996 to 1999 model years, it can be seen in that the quantity of older vehicles is far greater for pickups. Grupo Trafalgar SC 13.8 percent of the pickup population is prior to 1981 model year. 14.0 percent of the population is between 1981 - 85 model years and 18.8 percent to the population ( 69,379 vehicles) is of 86 - 90 model years. 26.

The substitution of the VW Combi with class 3 based minibuses mainly Grupo Trafalgar SC accounts for the large number of these vehicles from 1991 to 1995 model years (41.0% of the total population). Historically, the most used vehicle for the pickup and delivery cycle in Mexico City was a class 3 (10,000 lb.) stake truck. In this duty cycle, the introduction of vans has recently substituted in this class of vehicle to a great extent. Here, 40.8 percent of the current total population (62,613 vehicles) is prior to the 1991 model year. 28.

As a result, there are no vehicles in this range of model years in the population. Of the total of 40,990 gasoline powered class 5 & 7 vehicles in the ZMVM population, only 29 percent (11,864 vehicles) are of 1991 model year or more recent vintage. The other 71 percent are principally of 1976 to 1985 model years. 30.

This population at the end of 1999 is 15.8 years old on average whilst in the rest of the country this gasoline powered population is 14.7 years old. In 1985, in the ZMVM population the average age was 9.1 years whilst for the rest the Grupo Trafalgar SC country the average age was 8.5 years. This is markedly different for the diesel powered fleet of vehicles in the same vehicle weight class where the average age is approximately half this current value. 31.

In 1985, the average engine displacement outside of the ZMVM was 3.4 liters whilst in the ZMVM the average engine displacement was 3.2 liters. By 1999 the average displacement has dropped in both cases. Outside of the ZMVM the average displacement is 3.14 liters whilst within the ZMVM the average displacement is 2.77 liters. 48.

It can be seen in that for those vehicles with four cylinder engines, the vehicles with the larger displacement engines tend to cover higher mileages than those with lower displacements. The same Grupo Trafalgar SC tendency is evident for those vehicles with eight cylinder engines however no clear tendency can be seen for those vehicles with six cylinder engines. For the vehicles with four cylinder engines, those with a displacement of less than 1.5 liters have an average annual mileage of 16,860 whilst those with engine displacements above 1.5 liters have an annual mileage of 20,380. For those vehicles with eight cylinder engines, the annual mileages vary between 14,750 and 20,360 according to engine displacement. 49.

In the van wagon segment the average number cylinders in 1999 is 6.1 up from the average of 4.5 in 1985. For pickups, in 1999, the average number of cylinders is steady in 6.2, the same as it was in 1985. Also for class 3, there has been no change in the average number of cylinders in the ZMVM population, saying stable at 7.95 - 7.99 over the 15 year period.

For the van / wagon segment the average engine displacement has increased from 2.21 liters in 1985 to 3.77 liters in 1999. The pickup segment has shown only a slight movement; in 1985 the average displacement was 3.88 liters and in 1999 this has changed to 3.97 liters. For class 3 vehicles that has been no detectable change in their average displacement whilst for class 5 & 7 vehicles the same situation appears where the average displacement has changed by only 77 cc to 5.8 liters in 1999. 51.

In 1985 the cars in the vehicle population, on average, had a weight of 1289 kilos, this being the unladen weight of the vehicle with the driver, fuel and 50 kilos load. By 1999 this average weight for cars had dropped 8% to 1189 kilos. The average weight of the van/wagon segment over this 15 year period has increased by 28 percent from 1383 kilos in 1985 to 1773 kilos in 1999. Pickups, over the 15 year period under investigation, have shown a weight change of 2.7 percent going from 1735 kilos 1985 down to 1689 kilos in 1999. For class 3 vehicles the weight change has been only 1.1 percent going from 1931 kilos in 1985 down to 1910 kilos in 1999. The class 5 & 7 gasoline powered vehicles increased in weight over this period by 1.8 percent from 3225 kilos to 3284 kilos in 1999. The average vehicle for the complete ZMVM population has dropped by 7.3 percent over this 15 year period going from 1472 kilos in 1985 to 1365 kilos in 1999. It is important to note that the average vehicles in the ZMVM population are lighter than those in the rest of Mexico (excluding the ZMVM). In 1999 overall mean weight of the vehicles outside of the ZMVM is 6.8 percent greater than those within the capital city's metropolitan area. 52.

Now, only 34.7 percent of the car population is without a converter. 58.4 percent has a 3 way closed loop catalytic converter, 3.9 percent as a three way open loop catalytic converter and the remaining 2.9 percent as a two-way oxidizing converter. Grupo Trafalgar SC The 3 way closed loop catalytic converters started appearing in the market in 1990 (1991 model year) whilst the two-way converters and three way open loop converters were only introduced into the population during '91 and 92.

Due to their greater gross vehicle weight, these multiple use vehicles were classified under the current emissions regulations for in use vehicles in the same category as pickups and hence three way closed loop converters didn't started appearing in this vehicle population until 1993.

The graph shows the accumulated distribution of carbon monoxide in the sample obtained during 1999 from vehicles in model years between pre-1990 and 1994. The emissions readings shown on this graph are those obtained during the emissions test at 40 kph with an applied road load. This stage of the emissions test produces the highest carbon monoxide readings whilst the lower speed and high load section of the test (50% load at 24kph) produces higher hydrocarbon and NOx readings. You can see in the accompanying graph that the accumulative curves for vehicles up to 1993 model year are very similar whilst those from the 1994 model year show a cleaner emissions spectrum. To illustrate to this point, 95 percent of the vehicles from the 1994 model year have carbon monoxide emissions of less than 0.5 percent. At this same concentration level, only 67 percent of vehicles from the 1993 model year are within this 0.5 percent limit. For 1992, only 56 percent have CO emissions lower than 0.5 percent whilst for 1991, 64 percent are within this limit and for all the model years up 1990 only 54 percent were found to be within this limit. For this limit, you can see that all model years up to 1993 are covered within a 14 point spread whilst the difference between this group and 1994 is more than 30 points. Grupo Trafalgar SC 68.

Here again, the graph shows the accumulated distribution of carbon monoxide in the sample obtained during 1999 from vehicles produced with this type of converter. You can see that both model years have almost identical carbon monoxide distributions. Using the same example as in the previous graph, you will see that of the 1991 model year vehicles, 70.1 percent of the population have carbon monoxide emissions during this stage of the test of less than 0.5 percent whilst for the 1992 vehicles, 67 percent have emissions of less than 0.5 percent. This compares favorably with the average 60 percent of vehicles, these same model years with no catalytic converter that are within this .05 percent limit. Grupo Trafalgar SC 69. CO distribution of vehicles with Three Way Open Loop Catalytic Converters Sample period 1999 100% 90% 80% 70% 60% 1991 1992 1993 50% 1994 40% < 0.10 < 0.40 < 0.70 < 1.00 < 1.60 < 2.20 < 2.80 Cumulative distribution of CO from vehicles with 3 way Open Loop This graph shows the distribution of carbon monoxide emissions from those vehicles in the ZMVM population with three way open loop catalytic converters. The data was taken in the samples during 1999 and comes from vehicles whose model years are between 1991 and 1994. This data was obtained during the 40 kph stage of the emissions test. You can see that these model years fall into two distinct groups. The 1991 and 1992 model year vehicles have very similar CO emissions spectrums whilst the 1993 and 1994 model year vehicles are considerably cleaner. To continue with the same example, 72.6 percent of the 1991 model year vehicles have CO emissions of less than .5 percent. For the 1992 model year vehicles 75.8 percent have carbon monoxide emissions of less than .5 percent. On comparing these figures to the previous graph, you can see that the three way open loop catalytic converter produces slightly lower CO emissions than the two- way converter in the '91-'92 model years. The 1993 and 1994 model year vehicles are shown to be considerably cleaner with 93.9 percent and 92.3 percent respectively, being within the 0.5 percent carbon monoxide emissions figure.

The widespread use of this type of catalytic converters in Mexico started in 1991 in luxury cars and extended down to the economy and compact car ranges on or after 1993. In this graph you can see that the vehicles of up to the 1990 model year have higher CO emissions in general than those from later years. In fact, only 61.5 percent of these vehicles have CO emissions of less than 0.5 percent. The vehicles of 1991, 1992 and 1993 model years form a sub-group with between 88 percent and 91 percent meeting a 0.5 percent CO target. The 1991 and 1992 model year vehicles with three way closed loop catalytic converters are cleaner than the corresponding units with three way open loop catalytic converters. However, for the 1993 and 1994 model years the use of a three way closed loop catalytic converter does not show up in lower carbon monoxide emissions against those with open loop units. It is interesting to note the continuous improvement in carbon monoxide emissions against model year. Even though each model year does not have distinct pass/fail limits, or even distinct technology, there is a direct relationship between carbon monoxide emissions and vehicle model year. This carbon monoxide data probably does not support any decision to mandate changes of catalytic converter for vehicles with model years from 1994 to date. The spread across all vehicles of these model years to meet the 0.5 percent carbon monoxide level is only 5.9 percentage points. That is, 93.3 percent of the 1994 model year vehicles have less than 0.5 percent carbon monoxide whilst for the 1999 model year, 99.2 percent of vehicles have less than 0.5 percent CO. Grupo Trafalgar SC 71. CO distribution by Catalytic Converter Type - 1993 model year 100% 90% 80% 70% 98.2 99.2 60% < 0.10 < 0.40 < 0.70 < 1.00 < 1.60 < 2.20 < 2.80 1993 Model Year Vehicles with 3 way Closed Loop Cats Sampled in 98.2 and 99.2 During 1999, the Mexico City government mandated that all 1993 vehicles with three way catalytic converters had to renew their converters for the vehicle to obtain the "zero" sticker that allows it to operate all the days of the week. This converter renewal was voluntary during the 1st semester of 1999 depending on the emissions levels of the vehicle and was made obligatory during the second semester of that year. Thus, if we compare the CO emissions from the 1993 model year vehicles with three way closed loop catalytic converters sampled in the second semester of 1998 and in the second semester of 1999 we should be able to visualize the results of this action. As you can see in the accompanying graph the emission results of carbon monoxide taken during the 40 kph stage of the test show a deterioration between the second semester of 1998 and the second semester of 99. This is consistent with the other graphs and model years whether there is at a direct relationship between emissions level by model year and a deterioration over time, however, in this specific case we would have expected to see some benefits from the mandatory renewal of catalytic converters.

The figures shown here are mean carbon monoxide emissions from the ZMVM population of cars taken from the 1999 sample. The results are those of the 40 kph section of the emissions test where road load is applied to the vehicle. Those vehicles of between the 1984 and 1990 model years have the highest mean CO emissions levels at 0.73 percent average. But from 1991 on, the relationship is almost the linear from a peak of 0.30 percent (average 91-92) down to a mean CO level for 1999 model year cars of 0.06 percent. Grupo Trafalgar SC 73.

For each year, the results shown on this graph are the average of the results from the first and second semester of that year. Here you can see that for almost all model years, the carbon monoxide average emissions from cars in the ZMVM population measured as a concentration (percent) increased between the 1995 sample and the 1997 sample. For those vehicles with older technology (up to 1995 model year), the increase in test time that went into force in the latter half of 97 has apparently helped lower carbon monoxide readings to be reported. For the vehicles of 1996 model year onwards this reduction is not evident and the CO level of emissions from these vehicles has remained sensibly constant. Grupo Trafalgar SC 74.

From the 1991 model year onwards an almost linear relationship is again displayed between CO emissions and vehicle model year. Interestingly, the carbon monoxide average emissions went up between 1991 and 93 from 0.21 percent to 0.31 percent but from 94 onwards this level drops consistently to reach 0.05 percent by the 1999 model year. The improvement in mean carbon monoxide emissions from this class of vehicles is very similar to that shown in by cars even though these two segments are of different gross vehicle weights, different legislated limits, and different vehicle technology. Grupo Trafalgar SC 75.

The different model years, here, do not display consistent tendencies. You can see that the 1991 model year maintains an average carbon monoxide level in the band between 0.19 percent and 0.29 percent. The 1992 model year however shows a far wider distribution with the average carbon monoxide levels increasing with time. For the 1993 model year however the CO average levels show an almost straight line reduction over the five-year period. A similar tendency is shown for 1994 but at a lower average level going from 0.31 percent in '95 down to 0.14 percent in 99. For the 1995 model year, between 1997 and 1999 samples the tendency is very similar to 1994, however the average results in the 1995 and 1996 samples are substantially lower than those of this previous model year. For the 1996, 97 and 98 model years the results are consistent and do not show an improvement is carbon monoxide emissions with model year maintaining a need of between 0.5 and 0.12 percent.

The CO levels are high up until the 1993 model year varying between 0.94 percent and a low of 0.66 percent and then, with the requirements to fit three way closed loop catalytic converters this average level falls dramatically in 1994 to 0.17 percent and drops linearly with age until 1998. Here it is interesting to note that the average carbon monoxide emissions from the 1999 model year vehicles is substantially higher than those from previous model years. 77. Mean CO from pickups by model year. 1991 1.20 1992 1993 1994 1.00 1995 1996 1997 0.80 1998 0.60 0.40 0.20 0.00 1995 1996 1997 1998 1999 Mean CO emissions from Pickup by Model Year in 5 Samples (95-99) These two tendencies are also clearly apparent when we see the change in the average carbon monoxide emissions over the 5 different annual sampling periods. The CO emissions from vehicles of the 1994 and later model years are steady over time and fall in Grupo Trafalgar SC a band between a high of 0.26 percent and 0.06 percent with each model year are having lower average CO emissions than the previous one. For the 91, 92 and 93 model years however the average emissions are substantially higher and less consistent over time. 78.

The exception here is for the 1993 model year where the average carbon monoxide emissions measured in 1995 was Grupo Trafalgar SC 2.75 percent, considerably higher than anything else measured. This 93 model year also showed an increase in emissions during 1998 that was not a presented by any of the other vehicle segments. 80.

Here it can be seen that the different model years fall into two groups: up to 1993 and 1994 on. For the first group, the mean CO emissions continue dropping each year whilst for the later model years, the mean emissions are stable or increasing. The change in test protocol for `98 and `99 to a longer test time is believed to be the principal reason for the drop in mean emissions for these years. Whilst there is a definite mean CO improvement from model year to model year, information is not available to support the reasons behind the constant reduction in mean levels from the older model years against sampling period.

Here it can be seen that this covers only 1991 and 1992 model year cars with an unexplained difference between the two. It is important to note that this group represents the smallest portion of the population. 82. Mean CO emissions by model Year from vehicles with 3 Way Open Loop Catalytic Converters. 1.00 1991 1992 0.90 1993 0.80 1994 0.70 0.60 0.50 0.40 0.30 0.20 0.10 0.00 1995 1996 1997 1998 1999 Mean CO Emissions by Model Year & Sample Period - 3 Way Open Loop Converter This chart shows the change in mean carbon monoxide emissions, measured during the 40 kph stage of the emissions test, for each model year over the five-year span that our sampling periods cover for all vehicles that are fitted with 3 Way open Loop Catalytic Converters. Grupo Trafalgar SC Here it can be seen that there is a clear difference between the two model year groups. For the 1991-92 model year group, the mean CO emissions continue dropping each year whilst for the later model years, the mean emissions are stable. If the test protocol had not been changed for `98 and `99 to a longer test time, it is probable that the 1993-94 model year group would have shown an increase. This graph does not show any evidential benefits from the mandated converter change for the 1993 model year vehicles in 1999. 83.

Here it can be seen that the different model years fall into three groups: pre'91, 1991 to 1993 and 1994 on. For the first group, it must be assumed that the catalytic converter is not working at all For the second group, the mean CO emissions continue to drop slightly each year whilst for the later model years, the mean emissions are relatively stable. The change in test protocol for `98 and `99 to a longer test time is believed to be a major cause for the no- increase in levels during 1998 and 1999. Grupo Trafalgar SC 84.

The data for these graphs comes from the 40 kph section of the emissions test in which a road load is applied to the vehicle. It can be seen that up to and including the 1991 model year, the emissions reported from private and from commercial vehicles are very similar. Between the 1992 and 1995 model years however the commercial vehicles reports considerably higher carbon monoxide average emissions than private vehicles. From the 1996 model year onwards there is no difference reported in mean carbon monoxide emissions by type of service. Grupo Trafalgar SC 85. Mean CO emissions by number of Cylinders.

The data for this graph also comes from the 40 kph section of emissions test in which road load is applied to the vehicle. It can be seen her that from the 1991 model year to date the six cylinder engine generates lower mean carbon monoxide emissions than all the years and that the mean emissions per model year decrease proportionately. In the 1991 model year those vehicles with six cylinder engines show on average 0.15 percent of carbon monoxide and this figure drops linearly to reach 0.05 percent CO for the 1999 model year. Over the same period, those vehicles fitted with 8 cylinder engines saw a decrease in mean carbon monoxide emissions from 0.29 percent in the 1991 model year to 0.14 percent for the 1999 model year. The vehicles with 4 cylinder engines in the sample showed higher mean carbon monoxide emissions for model years between 1991 and 1994 and thereafter emissions levels similar to those reported by 8 cylinder engines.

For those vehicles that cover less than this average mileage, the mean CO emissions are lower than for those vehicles that cover more than this average mileage. In the above graph it can be seen that the difference is approximately 10 percent or in other words for the 1991 model year the higher mileage vehicles have on average 0.06 percentage points higher mean carbon monoxide emissions than the low of mileage vehicles. This difference drops to 0.02 percentage points for the 1999 model year vehicles. 87.

The mean carbon monoxide emissions level is more closely related to vehicle model year than to the amount of use the vehicle has had. 88.

The sample period for these results is 1999 and the model years of vehicles that are present in the ZMVM fleet without a catalytic converter is between 1984 and 1994. The results shown are from the segment of the test with 50 percent applied load at 24 kph (ASM 5015). It can be seen in that the emissions levels from these vehicles fall into three distinct groups. The vehicles from model years of up to 1990 have the highest hydrocarbon emissions and only 44.2 percent of vehicles have less than 100 ppm HC. 1991, 1992 and 1993 model years have very similar emissions distributions, where 68.2 percent, 69.5% and 75.9 percent of vehicles, respectively, have less than 100 ppm HC emissions. The vehicles from the 1994 model year with no catalytic converter are sensibly cleaner than the others; 94.3 percent of these vehicles have less than 100 ppm HC emissions. Grupo Trafalgar SC 89.

The above graph shows a very similar distribution of hydrocarbon emissions from both of these model years. You can see that 62.2 percent and 69.1 percent of these vehicles, respectively, have less than 100 ppm HC emissions. Somewhat surprisingly, this is a slightly lower percentage than in those vehicles from the same model years that were not fitted with a catalytic converter. 90.

The HC emissions from Grupo Trafalgar SC these vehicles were obtained during the 1999 sample period and measured at 50 percent applied load and 24 kph (ASM 5015). The above graph demonstrates 2 distinct groups. The 1991 and 92 model years have very similar hydrocarbon emissions distributions. 77.8 percent and 78.8 percent of these vehicles respectively have less than 100 ppm HC emissions. The other group is conformed from the 1993 and 94 model years. For these, 96.1 percent and 95.1 percent respectively have less than 100 ppm HC emissions. It can be seen in that the 1991 and 92 model year vehicles with three way open loop catalytic converters have lower hydrocarbon emissions than those fitted with two-way catalytic converters. At the 100 ppm HC level, approximately 12 percentage points more vehicles with three way open loop converters meet the less than the 100 ppm HC target. For the 1993 and 1994 model years an improvement of almost 15 percentage points in shown over the 91-92 family. 91.

This figure increases with model year reaching a maximum of 99.1 percent of vehicles from the 1998 and 1999 model years that also meet this criteria. As with the carbon monoxide emissions, the hydrocarbon dirtiest obtained from the different samples does not reflect any improvements in hydrocarbon emissions that can be atributed to the mandated renewal of catalytic converters in 1993 model year vehicles during the second semester of 1999.

The data in this curve is taken from the 40 kph section of the emissions test where a road load is applied to the vehicle. Here it can be seen, as expected, that the three way closed loop catalytic converter gives the most consistent results maintaining the mean hydrocarbon emissions at approximately 25 ppm over a wide range of model years going from 1993 through to the 1999 model year. During the transition years of 91, 92, and 93 it can be seen that a big improvement was made by going first to the two-way oxidizing converter and then to a three way open loop catalytic converter. The surprisingly good results from vehicles with no converter in recent model years are due, in graet extent, to the success that Ford had with their LPG powered class 7 truck. Grupo Trafalgar SC 93.

It can be seen that the distribution of mean HC emissions by model year and by type of converter is very similar to the distribution at 40 kph.but that the levels are approximately 10 percent higher due to the higher load factor. This means an increase of between 2 and 5 ppm for those vehicles fitted with a three way closed loop catalytic converter. 94.

Grupo Trafalgar SC For the 1991-92 model year group, the mean HC emissions continue dropping each year whilst for the later model years, the mean emissions are stable. This graph does not show any evidential benefits from the mandated converter change for the 1993 model year vehicles in 1999. 97.

Here it can be seen that the different model years fall into three groups: pre'91, 1991 to 1993 and 1994 on. Discounting the pre 1991 vehicles, it can be seen that whilst the different model years form a homogeneous group, there is a real improvement in mean HC levels from model year to model year. This is independent of any changes in the test protocol that could modify the readings between the 1998 and 1999 sampling periods. Grupo Trafalgar SC 98. NOx distribution of vehicles with no converter Sample Period 1999 100% 90% 80% 70% 60% 50% 40% 30% 1990 1991 20% 1992 10% 1993 1994 0% Cumulative distribution of NOx from vehicles with no Converter This graph shows the cumulative distribution of NOx emissions sampled during 1999, from vehicles in the ZMVM population with model years between 1984 and 1994. The samples were taken at 24 kph and with a 50 percent applied load (ASM 5015). It can be seen that these model years form three distinct groups. The vehicles of up to 1990 model year are by far the dirtiest and only 33.1 percent of the vehicles had NOx emissions of less than 1200 ppm. The 1991, 92 and 93 model years have very similar nitrous oxide emission distributions. For these, between 47.3 percent and 52.7 percent of the vehicles of each model year have less than 1200 ppm of NOx emissions. As with the other gases, the 1994 model year vehicles with no converter are considerably cleaner than the other models. Of these, 88.4 percent of vehicles have less than 1200 ppm of NOx emissions under this test procedure. Grupo Trafalgar SC 99. NOx distribution of vehicles with two-way catalytic converters Sample Period 1999 100% 90% 80% 70% 60% 50% 40% 30% 1991 20% 1992 10% 0% Cumulative distribution of NOx from vehicles with 2 way Converter As expected, the vehicles that that were sold into the ZMVM population during model years '91 and '92 fitted with two-way catalytic converters are by far the worse when it comes to NOx emissions. Unleaded gasoline was not readily available during those years. In vehicles with two-way catalytic converters from the '91 model year, sampled during 1999, only 10.5 percent had less than 1200 ppm of NOx emissions. The 1992 model year vehicles faired only slightly better, with 15.1 percent of the ZMVM population having less than 1200 ppm NOx emissions. 100. NOx distribution of vehicles with three way open loop catalytic converters. Sample Period 1999 100% 90% 80% 70% 60% 50% 40% 30% 1990 20% 1991 1992 10% 1993 1994 0% Cumulative distribution of NOx from vehicles with 3 way Open Loop This graph shows the cumulative distribution of nitrous oxide emissions, from those vehicles in the ZMVM population that are fitted with three way open loop catalytic Grupo Trafalgar SC converters. The results shown are from samples obtained in 1999 at 24 kph and 50 percent applied load (ASM 5015). It can be seen that the 1991 and 1992 model years have very similar emissions distributions and that of these vehicles, between 30.8 percent and 33.4 percent, respectively, have less than 1200 ppm of nitrous oxide emissions. This undoubtedly is due to a great extent to the lack of availability of unleaded gasoline during this period. Whilst the HC and CO emissions from vehicles with three way open loop converters from the 1993 and 1994 model years was almost identical, in the case of nitrous oxides a big difference exists. The 1993 model year vehicles show up to a 17 percentage point improvement over the 1994 model year vehicles when measured against a limit of 1200 ppm NOx. This undoubtedly is due to the mandated renewal of catalytic converters for the 93 model year vehicles. As can be seen, 71.2 percent of the 1994 vehicles emitted during the test procedure less than 1200 ppm of NOx whilst 88.3 percent of the 93 model year vehicles met this limit. 101. NOx distribution of vehicles with three way closed loop catalytic converters. Sample Period 1999 100% 90% 80% 70% 1990 60% 1991 50% 1992 1993 40% 1994 1995 30% 1996 20% 1997 1998 10% 1999 0% Cumulative distribution of NOx from vehicles with 3 way Closed Loop Unfortunately, the improvement in NOx emissions from the 1993 model year vehicles that was seen with three way open loop converters is not to also apparent for those vehicles fitted with three way closed loop converters. Here the distribution by model year is as expected and as seen with HC and CO. The cumulative emissions distribution of the vehicles in the ZMVM fleet can be divided into four categories. The dirtiest group, of course, consists of those vehicles up to 1990 and for these, 44.3 percent would meet a 1200 ppm limit for NOx. The second group consists of the 1991 and 1992 model year vehicles of which between 53.3 and 56.4 percent respectively would meet a 1200 ppm limit. The third group consists of the 1993, 94 and 95 model years where between 71.9 percent and 86.3 percent of the vehicles showed results of less than 1200 ppm NOx. The cleanest group is that of 1996 and later model years where between 90.9 and 93.2 percent of those vehicles tested showed NOx emissions of less than 1200 ppm. As in the other Grupo Trafalgar SC magnitudes, the emissions levels seem to be directly related to the model year of the vehicle. 102. Mean NOx emissions from cars by model year 1,800 Sample Period 1999 1,600 1,400 1,200 1,000 800 600 400 200 0 84 - 90 1991 1992 1993 1994 1995 1996 1997 1998 1999 Mean NOx emissions in ppm from Cars by Model Year (24kph) This graph shows the mean nitrous oxide emissions in ppm, for cars in the ZMVM population. The results are shown by model year. The results were taken during the sampling period of 1999 and the nitrous oxide emissions when measured under 24kph and 50 percent load (ASM 5015) conditions. It can be seen that there's almost a linear relationship between the NOx emissions in ppm and the vehicles model year dropping from a mean of 1370 ppm for the 1991 model year to 271 ppm for the 1999 model year. Grupo Trafalgar SC 103. Mean NOx emissions from vans and wagons by model year 1,600 Sample Period 1999 1,400 1,200 1,000 800 600 400 200 0 84 - 1991 1992 1993 1994 1995 1996 1997 1998 1999 90 Mean NOx emissions in ppm from Van/Wgn by Model Year (24kph) For vans and wagons segment of the ZMVM population the same is true, except for the 1993 model year which shows an unusually high mean nitrous oxide emission level at 1370 ppm. Apart from this 1993 peak, the mean vans and wagons segment distribution by model year is considerably flatter than the car distribution going from a high of 867 ppm for the 1991 model year to 112 ppm for the 1999 model year. 104. Mean NOx emissions from pickups by model year Sample Period 1999 1,600 1,400 1,200 1,000 800 600 400 200 0 Mean NOx emissions in ppm from Pickup by Model Year (24kph) The pickup segment of the ZMVM population also shows an un-characteristically high NOx level for the 1993 model year vehicles plus a similar but lower level for 1992 of 1378 ppm and 1025 ppm respectively. Since most of the sports utility vehicles (multiple use vehicles) and pickups in this model year have similar ansestry the relationship between these two peaks is logical. Apart from these exceptional years, the mean nitrous Grupo Trafalgar SC oxide emissions dropped from 910 ppm for the 1991 model year to a mean of 293 ppm for the 1999 model year vehicles. 105. Mean NOx emissions from Class 3 vehicles by model year Sample Period 1999 1,200 1,000 800 600 400 200 0 Mean NOx emissions in ppm from Class 3 by Model Year (24kph) The population of class three vehicles in the ZMVM does not demonstrate an improvement in nitrous oxide emissions with model year. The overall tendency, in fact, is towards a slight increase in nitrous oxide emissions as the vehicles get newer. Here, the exception to this tendency is the 1992 model year when the vehicles in this period showed a mean nitrous oxide concentration of 455 ppm. All these results were taken during 1999 when the nitrous oxide emissions when measured at 24 kph and 50 percent load conditions. The overall tendency goes from a mean of 889 ppm of nitrous oxide for the 1991 model year to the 935 ppm for the 1999 model year. No graph is presented for classified and seven gasoline part of vehicles because the size of the samples in 1999 is not sufficient to guarantee the statistical significance of the results. Grupo Trafalgar SC 106. Mean nitrous oxide emissions by type of service. 1,800 Sample Period 1999 1,600 Private Commercial 1,400 1,200 1,000 800 600 400 200 0 84 - 90 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 Mean NOx emissions in ppm by Type of Service (24kph) This graph shows mean nitrous oxide emissions, for the ZMVM population, sampled in 1999, by a vehicle model year and usage. For model years prior to 1993 it can be seen that those vehicles with commercial usage, (i.e. vehicles that are registered to companies for their own usage), have lower NOx emissions than vehicles that are registered to private individuals. For 94, 95 and 96 model years the difference in reversed and on average those vehicles with commercial usage have approximately 200 ppm higher NOx emissions than those vehicles registered for private usage. From the 1996 model year onwards, no difference in nitrous oxide emissions can be seen against vehicle usage. 107. Mean NOx emissions by Number of Cylinders. Sample period 1999 2,000 1,800 4-5 cyl 1,600 6-7 cyl 1,400 8 or more 1,200 1,000 800 600 400 200 0 84-90 91 92 93 94 95 96 97 98 99 Mean NOx emissions by No of Cylinders (24kph) This graph shows the mean NOx emissions by model year from the ZMVM population in a sample taken in 1999. All the data on this graph comes from the 24 kph section of Grupo Trafalgar SC the emission test where the load apply is that which would allow the vehicle to accelerate at half of the maximum FTP 75 acceleration rate. Here it can be seen that since the 1992 model year, the 6 cylinder engines have the lowest average NOx emissions going from 489 ppm for 1991 down to an average of 80 ppm in 1999. The 4 cylinder engines up until the 1998 model year show the highest average NOx emissions going from a peak of 1850 ppm in 1992 down to 283 ppm in the 1999 model year. Only for the 1998 and 1999 model years do the 4 cylinder engines show lower mean NOx emissions than the 8 cylinder engines. Apart from these years, the 8 cylinder engines have mean NOx emissions levels that are between those of the four cylinder and six in the engines. 108. Mean NOx emissions by kilometers per year. Sample period 1999 1,800 1,600 <20,000 1,400 >20,000 1,200 1,000 800 600 400 200 0 84-90 1991 1992 1993 1994 1995 1996 1997 1998 1999 Mean NOx emissions by High&Low Km/Yr (24kph) On average, the vehicles in the ZMVM population drive approximately 20,000 kilometers per year. In this graph it can be seen that those vehicles that cover less than this average figure have lower mean nitrous oxide emissions than those vehicles that have a higher mileage. For the model years of 1993 through to 1997, the higher mileage vehicles have, on average, nitrous oxide emissions of approximately 150 ppm more than those vehicles with the lower mileage. For the 1998 and 1999 model years, the difference between the two drops to a approximately 65 ppm. Grupo Trafalgar SC 109. Mean NOx emissions by Total Kilometers. Sample period 1999 1,600 <20k 1,400 20-50k 50-100k 1,200 100-200k 200-300k 1,000 300-500k >500k 800 600 400 200 0 84-90 1991 1992 1993 1994 1995 1996 1997 1998 1999 Mean NOx emissions by Total Kms (24kph) This graph shows the mean nitrous oxide emissions of the vehicles in the ZMVM population, taken in a sample during 1999, by model year and distributed according to the total number of kilometers that the vehicle has operated for. Here it can be seen that those vehicles with 50,000 kilometers or less total overall mileage are the vehicles that have closest to average mean emissions for almost all of the model years going from approximately 1000 ppm of NOx in 1990 down to approximately 330 ppm of NOx in 1999. As the total kilometers run increases going from 50,000 kilometers to 200,000 kilometers overall, the mean nitrous oxide emissions from the vehicle increase reaching a peak in those vehicles that have operated in total between 100 and 200,000 kilometers. For higher mileages, the mean nitrous oxide emissions go down and do in fact go to less than the original low mileage figure. Here they drop to approximately 670 ppm for 1990 model year vehicles with over 500,000 kilometers down to approximately 325 ppm for 1996 model year vehicles with the same overall mileage. There is, however, a strong element of statistical noise associated with these figures because of inaccuracies in data collection and factors such a speedometer repair. Grupo Trafalgar SC 110. Mean NOx at 40 K. P.

Here it is fascinating to note the linear relationship between the vehicle model year and average nitrous oxide emissions and it can be seen that all types of converter, except in the two- way oxidizing converters, follow the same overall tendency. Here it can also be seen that going from cars with no converter to cars with two-way oxidizing converters did, in fact, increase the mean NOx emissions of those vehicles by approximately 40 percent. It is conjectured that the low mean NOx emission level for the 1993 model year vehicles fitted with open loop catalytic converters is due in part to the retrofit program that was in force during the sample year. If so, this graph would tend to suggest that there are no major gains to be made in mean nitrous oxide emissions levels by retrofiting converters to 1994 or more recent model years.

Here, a similar distribution can be seen for each type of converter but, due to the higher load levels, the absolute average nitrous oxide emissions levels per model year are approximately 40 percent higher, going from 1352 ppm for the 1991 model year down to an average of 277 ppm for the 1999 model year, this for vehicles fitted with three way closed loop catalytic converters. There is little doubt that this high load stage of the test is important for measuring NOx levels and, of course, for warming and igniting catalytic converter. 112. Converter Efficiency The evaluation of a vehicle's emissions levels, via constant speed loaded mode testing (ASM protocol), is a simple and effective method of determining if the overall emissions control systems and engine systems in the vehicle are up to standard. Should the vehicle not to meet its emissions target, however, this test only provides limited information as to which component has failed. Specifically, for those vehicles with catalytic converters, a high NOx, hydrocarbon or carbon monoxide reading could be caused by a catalytic converter failure or could either be caused by the failure or lack of calibration of a number of other components or systems. Unfortunately, the most effective means of determining the efficiency of a catalytic converter is also time-consuming. There is undoubtedly great value in using a GM style propane enrichment test or by directly measuring the exhaust gas concentrations before and after the catalytic converter but none of the current test lanes in the emissions test centers are capable of performing this on a production basis. One indication of a catalytic converter failure would be a high level of carbon monoxide in the exhaust gas, provided that it is accompanied by sufficient oxygen that, should the converter have been working, would have allowed the catalytic process to take place. Grupo Trafalgar SC The maximum level of carbon dioxide should also be below a certain figure to ensure that the lack of conversion was not due to a saturation problem. Following this logic, it could be considered that a catalytic converter be defective if the CO level is greater than 0.3 percent whilst the oxygen level in the exhaust stream is greater or equal to 0.4 percent and the carbon dioxide level is less than 14 percent. This set of conditions has been used by the California Air Resources Board since the BAR90 Extended Testing program to evaluate, with available data, the percent of defective catalytic converters found during testing. This formula is considered to be favorable to the vehicle owner. It is more likely to report a catalytic converter in good condition that should have failed (false Pass) than to report as failed, a catalytic converter that is in good condition (false Fail). It has been shown in another section of this report that a considerable number of vehicles in the ZMVM population are not turning up for emissions testing and do not appear in the 1999 sample. The distribution of these missing vehicles by model year leads one to conjecture that these vehicles are mainly those that would have probably failed the emissions test. The following series of graphs shows the percent of vehicles with defective catalytic converters, using the above formula, both for the 1999 sample of vehiclesand for the sample taken in the second semester of 1997. We believe that the lower percentage of defective catalytic converters that are shown by this formula in the 99 is due mainly to this missing vehicles factor. 113.

The 1997 data shows a failure rate of 44 percent for vehicles up to 1990 model year dropping to 10 percent for the 91 and 92 model years and down to 0.4 percent for the 1999 model year vehicles. The 1999 data shows a similar tendency but with lower values. Grupo Trafalgar SC 114.

The 1999 data shows a similar tendency but with values that are a lot lower. 115.

The 1999 data shows a parallel tendency but with lower values. Obviously, the above-mentioned figures have nothing to do with the two way converters lack of ability for reducing NOx emissions. Grupo Trafalgar SC 10. Source information 116. Vehicle Sales Data The vehicle sales data was obtained from the individual manufacturers and from the two vehicle manufacturers associations (AMIA and AMPACT). Detailed retail sales data was available for the vehicle dealers within the Federal District and surrounding 18 municipalities that form the ZMVM over the period of 1972 to 1998. At the wholesale level, detailed sales data by vehicle manufacturer and model was obtained from 1963 to date. Vehicle production data by manufacturer was available from 1960 to 1962 and overall total national production data was available from 1951 to 1959. From this, vehicle sales projections by model were made to estimate the sale of vehicles from each manufacturer by vehicle type and model from 1951 to 1960. The retail sales data from the ZMVM over the period of 1972 - 98 then allowed estimates to be made for the missing retail sales figures from 1951 on. For each of the resulting vehicle makes/models and model years covering the period of 1951-2000, the vehicle body style, the type of fuel system, air induction system, engine number of cylinders and displacement, type of catalytic converter, and vehicle weight were determined from original research conducted by Grupo Trafalgar updated with information from the emissions verification program. 117. Vehicle Samples A total of 14 samples of vehicles from the ZMVM population were structured, one per semester over the period of 1993 to 1999, from registers obtained from Verificenters within the ZMVM both from the Federal District and from the state of Mexico. A total of 3.6 million registers, after cleaning and auditing, were used for the analysis. From these it was determined in that the sample period in which most vehicles were present in the population (i.e. the least number of missing vehicles) was the first semester of 1997. Since this was the best period to use as a basis for determining the mortality curves, an additional and independent sample was gathered of 1.7 million vehicles within this semester, which was used to elaborate the mortality curves for the different vehicle categories. Sample Cases 93.1 48,470 93.2 144,681 94.1 82,323 94.2 93,217 95.1 73,367 95.2 68,739 96.1 422,137 96.2 457,754 97.1 544,217 97.2 332,541 98.1 713,712 Grupo Trafalgar SC 98.2 205,612 99.1 226,922 99.2 155,382 3,569,074 Total 97.1:Placas 1,736,157 5,305,231 Total Distinct sub-samples were developed for the kilometers per year and total kilometer run data since additional filtering was required. 118. Vehicle Population The population of vehicles within the ZMVM was determined directly from the mortality curves developed from field samples. The inter-comparison of populations developed from mortality curves based on the data in distinct semesters enabled the projection of missing vehicles to be made. For the national vehicle population, distinct mortality curves were used to take into account the longer vehicle lives can be expected in a rural environment. 119. Emissions Data All the emissions information presented in this report comes directly from field data obtained from tests developed in the Verificenters. It only information from reputable centers was used to reduce sampling error. If it must be appreciated, however, that there are two factors that complicate a comparison between the emissions results from different semesters. The first factor is one of missing vehicles. Between the first semester of '97 and the second semester of 99, 16.8 percent of the ZMVM vehicle population apparently disappeared from the verification database. Since it can be assumed that this percentage contains more dirty vehicles than clean vehicles, this skews the data for these years. Additionally, other major changes have occurred in the verificenter equipment level and protocols used. Here, it is considered that the 1999 data is the most statistically significant and representative of the current vehicle population particularly for vehicles with catalytic converters, but the omnipresent missing vehicle skew must be born in mind. Grupo Trafalgar SC 1. Work to be done In the author's opinion, distinct benefits would be obtained by carrying out the following programs. 1) In-use Emissions Data Whilst substantial data can be gleaned from the archives of the emissions verification program, little exists on the emissions levels from vehicles in everyday use. It is considered important to carry-out a field survey of in-use vehicles to determine their exhaust gas concentrations and mass emissions and to compare these against the results obtained during the verification tests. This would permit the contribution of mobile sources to the ambient emissions inventory to be determined with a considerably greater precision allowing more enlightened strategic decisions to be made on the future of this program. Whilst it can be shown that the ambient air quality has improved considerably since 1991, as the yearly emissions figures come down, more precise information is required to determine the future routes to follow. Information with this statistical significance is not currently available. All that the emissions verification data can show us are the levels that these vehicles produced during their tests on two days year and little evidence currently exists to relate this to their overall emissions levels during normal working life. The effects of stop-start operation and cold running must also be taken into effect. 2) Diesel Fleet Emissions Contribution A field survey is required to determine the contribution of the heavy-duty diesel fleet to the emissions inventory in the ZMVM. Whilst good figures exist on the total population all these vehicles in the country, no statistically significant information is available on the time and distance covered that these vehicles spend within the urban environment or of the load factors that are encountered. The true technological level of each of the engines involved should also be determined. Since the importance of diesel engine vehicles on particulates and aerosols is substantial, statistically significant data is required to define the most sensible course action to control these emissions. The deficiencies in the current diesel engine emissions verification program render the information obtained from this source useless in this regard. Grupo Trafalgar SC 3) Catalytic Converter Efficiency Study A test program to directly measure, using accepted techniques, the efficiency of catalytic converters in the field would be highly recommended before further decisions are made to mandate the renewal of catalytic converters. The data in this report suggests that the cost-benefit relationship of changing converters is not optimal but no direct measurement of converter efficiency exists with a strong enough statistical background that could be used as a basis for forming opinions and making decisions. 4) Revision of the Verification Program A detailed analysis and revision of the verification program in the ZMVM (both in the Federal District and in the state of Mexico) would be highly desirable to focus future actions on those areas that can generate the most benefits. It is important to include the administrative aspects of the program in this study since the quality and extent of the administrative controls that are applied have proven crucial to the overall impact on air quality is that this program can generate. 5) Extend Report Coverage to Other Principal Urban Environments We would recommend extending the coverage of the present report to the other principal urban areas within the country, namely Guadalajara and Monterey. 6) Mass Flow Analysis Study A study program should be conducted to evaluate the implications and benefits of changing the emissions protocols, test equipment and limits to generate ASM mass flow emissions data (in grams per km). Changing from concentration based emissions limits to a mass flow basis would enable the program to focus better on the social costs involved in different transport means on a passenger per km basis. The emissions of carbon dioxide as a pollutant should be included. Whilst the concentration based emissions limits have been more than adequate to bring the mobile sources emissions into a controlled environment over relatively short period of time, it is considered that a mass flow form of measurement will be required to develop a sustainable long-term program. Due to the time involved in generating sufficient statistical data to define new test limits and in equipping test centers, this study could allow strategic changes to be carried out within a 4-6 year time frame. 7) Evaporative Emissions Control Study A study should be conducted to evaluate the cost/benefits of incorporating evaporative emissions control in the mobile sources verification program. Measurement techniques should be evaluated and future limits proposed. 8) Emissions Warranty Study A detailed study should be conducted on the benefits and implications of mandating an emissions warranty for all new vehicles sold within Mexico. The track record of all the major vehicle manufacturers on exports from Mexico to the USA and Canada has shown that their manufacturing facilities within this country have the technology in place to produce vehicles that can be subjected to an extended emissions warranty. It is Grupo Trafalgar SC considered that this is an inescapable requirement towards achieving accountability and obtaining future reductions in vehicle emissions levels. 9) Limits Study Since the emissions verification program has come into effect in 1988, limits have been constantly reduced applying tighter and tighter controls to in-use vehicles. For the older vehicles, current limits are half their original value. An apparent result is a reduction in mean emissions over the years from each of the model year groups. However, the vehicle's emissions performance is clearly controlled by the technology with which it was manufactured and hence cannot be taken below a certain limit. Any intent to legislate tighter levels for that vehicle dramatically increases the probability that it will obtain the approval certificate by other non-conventional means. A technical study is required to determine these optimum limits for each contaminant and model year group to ensure that this continual reduction in limits is not in fact generating higher mobile source emissions during the other 363 days per year.
