TECHNICAL MEMORANDUM #1

DELAWARE DIVISION OF MOTOR VEHICLES VEHICLE EXHAUST EMISSIONS TEST

To describe the details of the DMV exhaust emissions test for HC and CO using DE '95 Inspection system composed of exhaust emissions and pressure test analyzers manufactured by Environmental Systems Products, Inc., E. Granby, CT (ESP)

Applicable to all gasoline (or alternate fueled) vehicles presented for inspection (regular renewal) in Delaware.

3.1 ESP Lane Operator's Manual, Version #2 (1997)

3.2 DMV 9701 Gas Calibration

3.3 ESP DW6 HT202561 (Rev. L 06/27/95)

3.4 Delaware exhaust emissions specification limits

3.5 ESP BAR 90 Certification for analyzer bench

3.6 ESP exhaust emissions measurement system P/N ESP 10364-2

4.1 The lane analyzer has successfully passed the calibration procedure or procedures noted in Sections 2.1-2.2 of the ESP Lane Operator's Manual and DMV9701.

4.2 The Certified DMV Technician has verified that the vehicle presented is a viable candidate for an exhaust emissions analysis using DE '95 equipment.

4.3 The DMV Technician verifies that the following criteria are satisfied prior to emissions analysis.

4.3.1 Analyzer is "clean"; a HC hang-up condition exists when HC reading is greater than 40 PPM and the analyzer "locks-out" until the purge indicates "clean".

4.3.2 After the Technician inserts the exhaust pipe probe insertion (see note (a)), to a minimum of 10 inches, the resultant sample dilution (CO+CO2) must exceed 6.0%. The analyzer indicates the presence of a failure condition (CO+CO2<6.0%) and indicates "test voided". If the (CO+CO2) condition is not satisfied, the subject vehicle FAILS the Delaware Emissions Test.

(a) Normally, the vehicle driver has been requested to "fast idle" the vehicle for 30 seconds prior to entering the inspection lane, however, the Technician does not verify this condition.

4.4 When those conditions indicated in 4.3 of this memorandum are satisfied, the analyzer begins a timed emissions test. The following sequence prevails:

4.4.1 The test sequence is:

4.4.1.1 The internal timer starts; the analyzer "collects" samples for 15 seconds at a rate of two samples per second;

4.4.1.2 At the 15 second interval, the analyzer compares the accumulated data to the applicable DE emissions specification for Hydrocarbons HC and Carbon Monoxide CO;

4.4.1.3 Should the analyzer determine that the accumulated data does not exceed specifications for both components, it stops testing and indicates that the vehicle has passed emissions testing;

4.4.1.4 If the above analysis indicates that the applicable specifications limits are exceeded, sampling continues at the prescribed rate for an additional 15 seconds;

4.4.1.5 During this additional 15 second interval the analyzer continually compares the resultant data to the applicable DE specification. If, during this time, the HC & CO data are within specification, sampling ceases and a PASS indication is indicated; If, at the end of a 30 second sampling, either or both the HC and CO data exceed specification, testing is terminated and a FAILURE is noted. An immediate exhaust emissions retest is provided to all vehicles failing their initial emissions test. Subsequent "retests" shall only be performed after a properly completed "DMV VEHICLE EMISSIONS REPAIR FORM" is presented.

Revised 12/29/1987

TECHNICAL MEMORANDUM #2

MOTOR VEHICLE INSPECTION AND MAINTENANCE PROGRAM EMISSION LIMIT DETERMINATION

The five vehicle age groups have different allowable emission rates in the idle mode due to the sophistication of the emission control equipment installed by the manufacturer. The only exception being the pre-1968 age group which had no pollution control apparatus, saved for a few vehicles with positive crankcase ventilation (PCV) valves. Installation of PCV valves was virtually a voluntary measure by auto manufacturers.

During the time period March 1 through June 30, 1982, data was being gathered by a mandatory emission inspection with voluntary repair, at the two vehicle safety inspection lanes in New Castle County. The Sun Model CEA-3023 Computer Emission Analyzer (hereafter called the analyzer) has the ability to store, on conventional data cassettes, all of the input required and the results of a test on every vehicle tested. This is to include date, time, vehicle age group, vehicle registration number, hydrocarbon (HC) and carbon monoxide (CO) emission limits for the particular vehicle age group and the actual HC and CO emissions from the tested vehicle. A paper printout of this information is given to the driver upon being tested. Test procedures were consistent with those described in Appendix B to Technical Memorandum #1.

During the voluntary emission program, the HC and CO emission limits programmed into the analyzer were, with one exception, the same as those used by the State of New Jersey in its I & M program. Using these limits or "cut points" for each vehicle type gave a very good frame of reference to analyze the limits applicable to Delaware.

In general, about 25% of the vehicles tested during that voluntary program failed to pass the New Jersey standards.

Emission limits for each age group and the failure rate as a percent are shown in Table 1 of this memorandum.

Table 1

Notes: (1) Hydrocarbon (HC) emissions expressed as parts per million (ppm) of non-methane HC.

(2) The New Jersey standards for 1980 and later models are 300 ppm of HC.

The rate of emission reduction required by the I & M program adoption must be at least 35% reduction of total HC emissions from tailpipe at the end of 1987. The 35% is defined as the difference in emissions of HC between the vehicle fleet not having I & M and that having I & M, in the urbanized portion of the ozone non-attainment area. Since the mechanics of testing only those vehicles registered to an address within the "urbanized"(1) area would be difficult at best, the entire county was included in the calculations for reductions.(2) The types of vehicles to be tested for emissions were broadened to include the two classes of light duty trucks, those under 6,000 pounds G. V. W. and those in the 6,000 to 8,500 pound G.V.W. class. These two measures reduced the estimated failure rate from the 20% of the urbanized auto and station wagon fleet, which is the target rate to accomplish the 35% reduction in the emissions, down to 15%.

Attached as Appendix A to this Technical Memorandum is an April 16, 1982, letter from the I & M staff at EPA's Ann Arbor office. This letter details their evaluation of a 10% stringency factor on the three LD classes of vehicles in NCC to provide at least 35% reduction in tailpipe emissions. Following up the EPA analysis is a similar analysis for the Delaware-specific data. With a 15% stringency factor the results show that a 39.7% reduction in HC will be realized when the same 1,083 factor for "entire county inspection" is applied. This is obviously a reduction in tailpipe HC emissions adequate to meet the EPA requirements.

The selection of cut points for each vehicle class was accomplished by computer storage and retrieval of the data. For each vehicle age group, the frequency of each emission reading was determined and the appropriate percentile selected as the cut point for that particular age group. For simplicity and reduced computer storage requirements each individual reading was grouped in sets of 5 ppm, in the case of HC, and in sets of 0.05%, in the case of CO.

Light duty trucks (pickups and vans) have different levels of emission controls than those of autos. Age groups of the two light duty gasoline truck classes LDGT1(3) and LDGT2(4) had to be fit into one of the auto age group levels of emission control. This determination was made by utilizing Table 7 of the January, 1981, EPA document entitled "Recommendations Regarding the Selection of Idle Emission Inspection Cutpoints for Inspection and Maintenance Programs". The final result of this exercise is shown in Table 2 of this memorandum, and this table represents the cutpoints adopted in the 1982 S.I.P. revision. Since the County of New Castle is non-attainment for ozone which is affected by HC, the rates shown for CO will be recorded, but failure of CO limits will not affect registration of the vehicle.

(1) The urbanized area as defined by the U.S. Bureau of the Census.

(2) This expanded the potential vehicle fleet by a factor of 1.083 which is the ratio of total NCC population to the urbanized area population.

(3) Truck with GVW less than 6,000 pounds

(4) Truck with GVW greater than 6,000 but less than 8,500 pounds
