EVALUATION OF MAREMONT NEW AFTERMARKET THREE—WAY CATALYTIC CONVERTER FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 AND TITLE 13, CALIFORNIA CODE OF REGULATIONS, SECTION 2222(h) I. INIRODUCTION Maremont Corporation of Carol Stream, Illincis, has applied for an exemption for their new aftermarket three—way catalytic converter in accordance with the California regulations on new aftermarket catalytic converters. The converter will be used only on fuel injected vehicles with maximum vehicle weight of 4,000 lbs and engine displacement of 5.7 liters (350 CID). II. CONCLUSION The applicant has submitted all the required information and based on the submitted exhaust emissions test data, the staff concludes that the catalytic converter meets the criteria set forth in Vehicle Code Section 27156 and Title 13, California Code of Regulations, Section 2222(h). III. RECOMMENDATION The staff recommends that the exemption be granted as requested. and that Executive Order No. D—184—3 permitting the advertisement, sales and installation of the new aftermarket three—way catalytic converter be issued. IV. DEVICEDESCRIPTION The Maremont three—way catalytic converter consists of honeycomb type substrates coated with platinum and palladium plus rhodium and enclosed in an outer shell or container of stainless steel.

The Maremont Corporation three—way catalytic converter uses materials and construction similar to the original equipment manufacturers. The catalytic converter is sold with installation instructions and kits as shown in the Maremont application catalog. The converter is also sold with a two year or 25,000 miles warranty on the substrates and five years or 50,000 miles on the container or shell. v. DEVICE EVALUATION Maremont Corporation provided test data for the three—way catalytic converter. The tests were conducted by Automotive Testing and Development Services, Inc. (formerly O1son Engineering, Inc.), Huntington Beach, California. Two CVS—75 emission tests were conducted on the test vehicle with the converter installed and two CVS—75 tests were conducted with exhaust backpressure simulator. The tests were conducted on a fuel injected 1988 Chevrolet Cheyenne with inertia weight of 4,750 1bs and engine displacement of 5.7 liters following the 25,000 miles mileage accumulation on each of the two test converters. The mileage accumulation vehicies were a 1980 Oldsmobile Delta 88 with inertia weight of 4,000 lbs and engine displacement of 5.7 Iiter§, and a 1980 Buick Electra Wagon with inertia weight of 4,500 tbs and engine displacement of 5.7 liters. The test results and conversion efficiencies are shown below: Simulator Converter 1 Converter 2 Average Efficiency HC 2.972 0.439 0 .445 85.1% C0O 18.148 3.818 3.718 79.2% NOx 1.085 0 .374 0 .383 65.1%

All of the conversion efficiencies meet the standards set by the California e regulation which are 70% for HC and CO, and 60% for NOx. The staff based the evaluation of the new aftermarket three—way catalytic converter on the test data from Automotive Testing and Development Services, Inc. In previofls testing on a carbureted vehicle, the same catalytic converters demonstrated average conversion efficiencies of 92.2% for HC, 82.0% for CO, and 58.2% for NOx. Based on these test results, the staff has limited the applicability of the converter to fuel injected vehicles only.
