CONCLUSION The applicant has submitted all the required information and based on the submitted exhaust emissions test data from Automotive Testing and Development Services, Inc. (ATDS), Ontario, California, and General Motor Test Laboratory, Panorama City, California, the staff concludes that the catalytic converters meet the criteria set forth in Vehicle Code Section 27156 and Title 13, California Code of Regulations, Section 2222(h) for the stated application. III. RECOMMENDATION The staff recommends that the exemption be granted as requested and that Executive Order No. D—378 be issued, permitting the advertisement, sale and installation of the new aftermarket catalytic converters.

IV. DEVICE DESCRIPTION Ceramic monolithic substrates which are coated with platinum and palladium are used in the manufacture of Delphi‘s new aftermarket three—way plus oxidation catalyst and oxidation catalyst. The substrates are wrapped with expanding paper or intumescent mat and enclosed in a clam shaped stainless steel shell using seam welding. Heat shields are welded on top and bottom of the converter shell to protect the vehicle underbody from excessive heat and accidental fire. The catalytic converters are sold with installation instructions, and may be sold with flanges, end pipes, and air— tubes as a kit in the application catalog. They are also sold with a warranty for 25,000 miles on the substrates and five years or 50,000 miles on the container or shell. v. DEVICE EVALUATION Delphi has submitted the test data on the catalytic converters from testing conducted at Automotive Testing and Development Services, Inc. (ATDS) in Ontario, California, and General Motor Test Laboratory (GMTL), Panorama City, California. Mileage accumulation for the two catalysts was conducted by ATDS. Emission tests were conducted with each of two test converters installed, followed by two CVS—75 tests with exhaust backpressure simulator. A 1977 6.6L Pontiac Grand Prix and a 1977 6.6L Oldsmobile Delta 88 were used as the mileage accumulation vehicles for the oxidation vehicle. A 1984 5.0L Buick LeSabre and a 1981 5.0L Oldsmobile Delta 88 were used as mileage accumulation vehicles for the three—way plus oxidation converter. Emissions tests were conducted using the 1984 5.0L Buick LeSabre for the TWC + OC and the 1977 6.6L Pontiac Grand Prix for the OC. The equivalent test weight (ETW) for the TWC + OC and OC were 4,000 lbs. and 4,500 lbs. respectively. Upon completion of testing at ATDS, the ARB conducted

confirmatory tests at the Haagen—Smit Laboratory, El Monte, California. The TWC + OC failed the NOx conversion efficiency, achieving 40.6 percent instead of the required minimum efficiency of 50 percent. The OC achieved only 67.9 percent af HC conversion efficiency instead of the required 70 percent. Upon request, Delphi was allowed to retest the converters in a different laboratory than ATDS. The second independent laboratory tests were conducted at General Motor Corporation‘s Laboratory in Panorama City, California. The test results from the GM Laboratory were averaged with the test gesults from ATDS to determine the performance of the converters. The test results and conversion efficiencies for the converter are shown below: ATDS, ONTARIO TWG + 0C Simulator Cat. #5440 Cat. #5441 Avg. Conv. Eff.

CO=95% for the OC. All of the conversion efficiencies meet the requirements of the California reqgulations. The staff based the evaluation of the aftermarket catalytic converters on the information submitted by Delphi and on test results from ATDS and GMTL. However, since the catalysts failed the ARB confirmatory testing, Delphi must conduct production audit testing as part of their first semi—annual production report, in accordance with Paragraph IX of California Evaluation Procedures for New Aftermarket Non— Original Equipment Catalytic Converters. Thereafter, the ARB may accept their quality control procedures.
