The converter part numbers are shown below: Converter Type Universal Part No. Direct—Fit Part No. TWC + OC 15140, 15141, 15142, 15143 15546, 15575, 15577 II. CcONCLUSION The applicant has submitted all the required information and based wn°m, 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 Reqgulations, 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—182—8 be issued, permitting the advertisement, sale and installation of the new aftermarket catalytic converter. IV. DEVICE_ DESCRIPTION The Walker three—way plus oxidation catalyst uses ceramic monolithi& substrates which are coated with palladium and rhodium. The substrates are enclosed in an outer stainless steel shell. Heat shields are welded on top and bottom of the converter shell. The catalytic converter is sold with installation instructions and kits as shown in the application catalog. Lsns

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 EVALUATION Walker has submitted the test data on the catalytic converter. The emission tests were conducted by Automotive Testing and Development Services, Inc. (ATDS), Huntington Beach, California. Testing consist of two CVS—75 emission tests on the test vehicle with the converter installed and then two CVS—75 tests with exhaust backpressure simulator. The two test catalytic converters were previously aged using two 1990 fuel injected Ford FP—250 trucks with 5.8L engine displacement, and 5500 l1b. vehicle test weight. The carry—over emission test vehicle was a 1992 TBI Dodge Ram B350, 5.9L and 5,500 lbs vehicle test weight. The test results and conversion efficiencies for the converter are shown below: Simulator Cconverter 1 Converter 2 Avgq. Conv. Eff. HC (g/mi) 2.451 0. 427 0.356 84.0% co (g/mi) 45.502 7.207 6.361 85.1% NOx(g/mi} 3.034 1.253 1.293 58.0% All of the conversion efficiencies meet the requirements of the California reqgulations. The staff based the evaluation of the new aftermarket catalytic converter on the information submitted by Walker and on test data from ATDS.
