WHEREAS, Walker Manufacturing Company (Walker), a division of Tenneco Automotive, of 2701 N. Dettman Road, Jackson, Michigan 49201, has applied to the ARB for exemption from the prohibitions in Vehicle Code Sections 27156 and 38391 to market their aftermarket series 44000 three—way catalytic converter (TWC) for the following application, except for vehicles equipped with an OBD II system: Type Use. Series No. Max. Eng. Size Max. Veh. Test Wt. TWC TWC 44000 4.3L (260 CID) 4,250 Ibs. WHEREAS, pursuant to the authority vested in the Executive Officer by Health and Safety Code Section 39515 and in the Chief, Mobile Source Operations Division by Health and Safety Code Section 39516 and Executive Order G—45—9, the ARB finds that the above aftermarket catalytic converter complies with the California Vehicle Code Section 27156 and Title 13, California Code of Regulations, Section 2222(h). Emission performance of the catalytic converter was based on durability bench—aging of the catalyst using AlliedSignal Environmental Catalyst (ASEC:) bench— aging cycle ARL—102 (RAT B) for 27 hours, accepted by the ARB for this application to be equivalent to 25,000 miles durability using the AMA driving cycle (Reference Appendix IV, Title 40, part 86, Code of Federal Regulations (June 28, 1977)). Whereas, emissions tests conducted at Automotive Testing and Development Services (ATDS), Ontario, California, showed the following conversion efficiencies which meet the minimum . requirements for new aftermarket catalytic converters: Catalyst Application Type Pollution Component TWC (% Conversion) HC: Min. Requirement 70 Walker‘s series 44000 77.6 CO: Min. Requirement 70 Walker‘s series 44000 79.0 NOx: Min. Requirement 60— Walker‘s series 44000 65.4

State of California AIR RESOURCES BOARD EVALUATION OF WALKER MANUFACTURING COMPANY‘S SERIES 44000 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) October 2000 by Mobile Source Division 9528 Telstar Avenue El Monte, CA 91731—2990 (This report has been reviewed by the staff of the California Air Resources Board and approved for publication. Approval does not signify that the contents necessarily reflect the views and policies of the Air Resources Board, nor does mention of trade names or commercial products constitute endorsement or recommendation for use.)

SUMMARY Walker Manufacturing Company (Walker), a division of Tenneco Automotive, of 2701 North Dettman Road, Jackson, Michigan 49201 has applied for an exemption of its series 44000 new aftermarket three—way catalytic converter (TWC) from the prohibitions in Vehicle Code Sections 27156, in accordance with California regulations on new aftermarket catalytic converters. The two test catalysts were aged using AlliedSignal Environmental Catalyst‘s (ASEC‘s) rapid aging cycle ARL—102 for a duration of 27 hours based on temperature histogram data collected by ASEC. The round substrate is of ceramic monolith type. The single substrate is coated platinum and rhodium in 2:1 ratio. The emission tests were conducted on a 1995 GMC Jimmy 4.3L truck at the equivalent test weight of 4250 pounds (Ibs.). The new catalytic converter is for installation on vehicles equipped with three—way catalytic converter (TWC) and the maximum application limits for the TWC are 4.3L and 4250 lbs., which corresponds to 4.3L engine displacement and gross vehicle weight of 4640 lbs. Emissions data submitted by the applicant show that the catalytic converter meets the requirements 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—27 be issued.

EVALUATION OF WALKER MANUFACTURING COMPANY‘S SERIES 44000 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) I. INTRODUCTION Walker Manufacturing Company (Walker) of 2701 North Dettman Road, Jackson, Michigan 49201, has applied for an exemption from the prohibitions in Vehicle Code Section 27156 for its series 44000 new aftermarket three—way catalytic converter (TWC) in accordance with California regulations on new aftermarket catalytic converters. AIIiédSignal Environmental Catalyst (ASEC) is the catalyst supplier of the new aftermarket catalytic converter. The new aftermarket catalytic converter is intended for the following vehicle applications: Converter Type Converter Use PN/Series Max. Eng.Size — Max.Veh.Test Wt. TWC TWC 44000 4.3L 4250 lbs. The maximum Gross Vehicle Weight (GVW) for the catalytic converter application is 4,640 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, except those vehicles equipped with On—Board Diagnostic II (OBD—II) system. 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 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.

[L. RECOMMENDATION Staff recommends that the exemption be granted as requested and that Executive Order No. D—182—27 be issued, permitting the advertisement, sale, and installation of the new aftermarket catalytic converter on applicable vehicles. IV. DEVICE DESCRIPTION Walker‘s new aftermarket TWC is designed to use a single round ceramic monolith substrate. The substrate is coated with platinum and rhodium in the 2:1 ratio. The dimensions of the substrate are 3.66 inches diameter and 4.00 inches in length. The volumse of the substrates is 42.1 cubic inches. The substrate is contained in outer 409 stainless steel shell with compressed intumescent or expanding mat, to prevent vibration and exhaust by—pass. The clamshell halves are sealed by seam weld, and the end pipes are attached to the shell by arc welding. Aluminized heat shield is spot—welded to the upper side of the converter to protect the vehicle underbody from excessive heat. The catalytic converter may be sold as a unit with installation instructions or may be used in customized direct fit exhaust applications. It is 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) laboratory, Ontario, California. Catalyst bench—aging was conducted by ASEC using its ARL—102 rapid—aging. The aging duration of 27 hours was calculated from temperature histogram obtained from vehicles similar to the one used on emission testing. The 27—hour aging duration was determined to produce aging severity similar to that which the catalyst would experienced when aged on the road for 25,000 miles using the

AMA driving cycie. Emissions tests were conduéted on a 1995 GMC Jimmy 4.3L. The test vehicle was ballasted to obtained the desired equivalent test weight of 4,250 lbs. The evaluation of the Walker‘s new aftermarket catalytic converter is solely based on the bench—aging conducted by ASEC and the emission tests conducted at ATDS. The limits of application of Walker‘s series 44000 TWC are 4.3L/4,250 lbs. and the corresponding maximum gross vehicle weight is 4,640 lbs. The two test catalysts were labeled 7808 and 7809 respectively. 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. The average of the two test results for each test catalyst was used to calculate the conversion efficiency. The overall conversion efficiency for the catalyst model is the average conversion efficiency of the two test catalysts. The test results for the catalyst are shown below: Automotive Testing and Development Services, Ontario, California TWC Simulator Catalyst 7808 Catalyst7809 Conv. Eff. Average Average Average Average HC (g/imi) 2.409 0.539 0.537 77.6% CO (g/mi) 16.108 3.207 3.552 79.0% NOx (g/mi) 2.281 0.753 0.826 65.4% The above conversion efficiencies meet the minimum requirements of the California regulations on new aftermarket catalytic converters. Duse to time constraints, the ARB did not conduct confirmatory testing on the catalyst.
