SUMMARY Walker Manufacturing Company (Walker) of 2701 N. Dettman Road, Jackson, Michigan 49201, has applied for an exemption of their new series 96000 aftermarket three—way catalytic converter ({TWC) from the prohibitions in Vehicle Code Section 27156, in accordance with California reqgulations on new aftermarket catalytic converters. The two test catalysts were aged using AlliedSignal Environmental Catalyst (ASEC‘s) bench—aging cycle, ARL—102. Each converter can contains one round substrate of ceramic monolith type. The substrate is coated with palladium and rhodium. The new catalytic converter may be installed on TWC and OC vehicles powered by an engine of 5.9L or less, and having an equivalent test weight of 6,000 lbs. or less. Emissions data submitted by the applicant show that the catalytic converter meets the fequirements of Vehicle Code Section 27156 and Title 13, California Code of Regulations, Section 2222(h) for the stated application. Based on the above, the staff recommends that the exemption be granted as requested and that Executive Order D—182—26 be issued.

EVALUATION OF WALKER MANUFACTURING COMPANY‘S SERIES 96000 NEW AFTERMARKET THREE—WAY CATALYTIC CONVERTER FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156, AND TITLE 13, CALIFORNIA CODE OF REGULATIONS SECTION 2222(h) ce I. PNTRODUCTION Walker Manufacturing Company (Walker} of 2701 N. Dettman Road, Jackson, Michigan 49201, has applied for an exemption from the prohibitions in Vehicle Code Ssection 27156 for their new series 96000 aftermarket three—way catalytic converter (TWC)} in accordance with California reqgulations on new aftermarket catalytic converters. The ceramic monolith substrate of the new catalyst was manufactured by AlliedSignal Environmental Catalyst (ASEC). The new aftermarket catalyst is intended for the following vehicle application: Converter Type Converter Use PN/Series Max. Eng. Max. Veh. Size Test Wt. TWC TWC 96000 5. 9L 6,000 lbs. TWC oC 96000 5.9L 6,000 lbs. Walker intends to market the new TWC as a replacement for catalytic converters on applicable vehicles whose manufacturers‘ warranty has expired and the need for replacement of the original equipment manufacturer (OEM} catalytic converter has been established and documented. Excluded from the application are those vehicles equipped with an On—Board Diagnostic System II (OBD—II)}. II. concLUSION The applicant has submitted all the required information, and based on the applicant‘s submitted exhaust emissions test data, the staff concludes that the new aftermarket catalyst meets the criteria set forth in Vehicle Code Section 27156, and Title 13, California Code of Requlations, Section 2222(h) for the stated application. III. RECOMMENDATIOfi Staff recommends that the exemption be granted as requested and that Executive Order No. D—182—26 be issued, permitting the advertisement, sale, and installation of the new aftermarket catalyst on applicable vehicles. IV. DEVICE DESCRIPTION Walker‘s new aftermarket TWC is designed to use round ceramic monolith substrate. The substrate is coated with palladium and rhodium. The substrate measures 3.66 inches in diameter and 5.00 inches in length, and has a volume of 52.66 cubic inches. The substrate is contained in outer 409 stainless steel shell with compressed intumescent mat, to prevent vibration and exhaust by—pass. The shell is sealed by seam weld, and bushings are attached by arc welding. Aluminized soft steel heat shield is spot—welded to the upper and bottom sides of the converter to protect

vehicle underbody from excessive heat, and prevent materials on the ground from direct contact with the catalyst shell. The catalyst may be sold as a unit with installation instructions or may be used in customizsed direct fit exhaust application. It is also sold with a warranty for 25,000 miles on the substrate, and five years or 50,000 miles on the container or shell, and the end pipes. v. DEVICE EVALUATION Walker submitted data from testing conducted by Automotive Testing and Development Services (ATDS), Ontario, California. The test catalysts were aged by AlliedSignal Environmental Catalyst using their ARL—102 bench—aging cycle. The test catalysts were shipped directly to ATDS where the emissions tests were conducted for three—way (TWC) application using a 1995 Dodge 2500 Ram Truck 5.9L. The oxidation catalytic converter (OC) application tests were conducted on a 1979 Ford Pickup Truck 7.6L,. However, the use of the 7.6L Ford Truck for the 0C testing will not change the application limits of the Walker‘s series 96000 TWC as shown above. All tests were conducted at the equivalent test weight (ETW) of 6,000 lbs. The test vehicles were ballasted in order to achieve the required ETW of 6,000 pounds. The test catalysts were labeled 6971 and 6972. Testing consisted of two cold—start CVS—75 with a simulator ("dummy" catalyst}), followed by two cold—start CVS—75 for each of the test catalysts. Upon completion of testing at the independent laboratory, the ARB conducted confirmatory tests for TWC application only at the Haagen—Smit Laboratory in El Monte, California. Results from the.confirmatory tests showed CO conversion efficiency for test catalyst 6971 to be only 60.7 percent which brought the overall performance of series 96000 TWC to 67.2 percent for CO. The minimum required conversion efficiency is 70 percent. Walker speculated that the test catalyst might have been damaged chemically or mechanically, and requested to be allowed to open it for mechanical and chemical analysis. The examination showed that the substrate was broken into two pieces. It was not determined whether the damage was caused by a drop of the test catalyst from a height or by vibration during testing. Walker requested to be allowed to re—age and retest another catalyst as a replacement. The replacement test catalyst was identified as 7107. All test results for the series 96000 TWC, including ARB‘s confirmatory tests, are shown below:

Staff recommends that exemption be granted on the basis of tests conducted at ATDS, which showed that both of the test catalysts meet the required minimum conversion efficiency.
