NEW AFTERMARKET OXIDATION CATALYTIC CONVERTER FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTIONS 27156 AND 38391, AND TITLE 13, CALIFORNIA CODE OF REGULATIONS, SECTION 2222(h) I. INTRODUCTION Car Sound Exhaust Systems, Inc. (Car Sound) of 22961 Arroyo Vista, Rancho Santa Margarita, California, has applied for an exemption from the prohibitions in Vehicle Code Sections 27156 and 38391 to allow the use ‘of their new aftermarket three—way plus okidation (TWC + OC) catalytic converter for oxidation application on vehicles up to 5.0L engine size and 4,000 lbs. vehicle equivalent test weight (ETW), in accordance with California regulations on new aftermarket catalytic converters. The converter series number and application are shown below: Converter Type Use Series No. Max. Eng. Size Max. ETW TWC + oc oC 22000 5.0L (302 CID) 4,000 lbs. 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) for the stated application. III. RECOMMENDATION The staff recommends that the exemption be granteé as requested and that Executive Order No. D—193—11 be issued, permitting the adve;tisement, sale and installation of the new aftermarket catalytic converter. IVv. DEVICE DESCRIPTION Ceramic monolithic substrates which are coated with palladium and rhodium are used in the manufacture of the three—way plus oxidation catalyst. The substrates are wrapped with expanding paper or intumescent mat and enclosed in a 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 converter is sold with installation instructions and kits as shown in the application catalog. It is 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 EVA#UATION Car Sound has submitted thé test data on the catalytic converter. Carry—over emissiqn tests were conducted by Automotive Testing and Development Services, Inc. (ATDS) in Ontario, California. The tests were conducted using a 1979 5.0L El Camino at the ETW of 4,250 lbs. Two CVS—75 —emission tests were conducted with the converter installed, followed by two CVS—75 tests with exhaust backpressure simulator. Confirmatory tests were conducted by the Air Resources Board (ARB) at the Haagen—Smit Laboratory in El Monte, California. The two test catalytic converters were previously aged using a 1984 and a 1985 Chevrolet Caprice at the ETW of 4,000 lbs. Therefore, the converter application is limited to the aging vehicle parameters of 5.0L/4,000 lbs. The test results aqd conversion efficiencies for the converter are shown below: ATDS,ONTARIO Simulator Converter 1 . Converter 2 Avg. Conv. Eff. HC (g/mi) 2.218 0.458° 0.519 78.0% co (g/mi) 32.700 6.834 7.290 78. 4% HAAGEN—SMIT LABORATORY, EL MONTE HC (g/mi) 2.191 0. 478 0.441 79.1% co (g/mi) ° 55.345 g.887 ° 10.715 81.4% All of the conversion efficiencies meet the requirements of the California requlations. The staff based the evaluation of the new aftermarket catalytic converter on the information submitted by Car Sound and on test results from ATDS and ARB.
