SUMMARY Car Sound Exhaust System, Inc. (Car Sound) of 22961 Arroyo Vista, Rancho Santa Margarita, California 92688, has applied for an exemption of their new series 97000 aftermarket three—way plus oxidation catalytic converter (TWC + OC) 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 (ASEC‘s) bench—aging cycle, ARL—102 (RAT B) for 53 hours. Each converter can contains two substrates of ceramic monolith type. The » front and rear substrates are coated with palladium and rhodium in 5:1 ratio. The new catalytic converter may be installed on TWC + OC, 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 requirements of Vehicle Code Section 27156 and Title 13, California Code of Regulations, Section 2222(h) for the stated applicatipn. Based on the above, the staff recommends that the exemption be granted as requested and that Executive Order D—193—18 be issued.

EVALUATION OF CAR SOUND EXHAUST SYSTEM, INC.‘S SERIES 97000 NEW AFTERMARKET THREE—WAY PLUS OXIDATION CATALYTIC CONVERTER FOR EXEMPTION FROM THE PROHIBITIONS IN VEHICLE CODE SECTION 27156, AND TITLE 13, CALIFORNIA CODE OF REGULATIONS SECTION 2222(h) I. INTRODUCTION Car Sound Exhaust System, Inc. (Car Sound) of 22961 Arroyo Vista, Rancho Santa Margarita, California 92688, has applied for an exemption from the prohibitions in Vehicle Code Section 27156 for their new series 97000 aftermarket three—way plus oxidation catalytic converter (TWC + OC) in accordance with California regulations on new aftermarket catalytic converters. The ceramic monolith substrates of the new catalyst were 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 + 0C TWC + 0C 97000 . 5.91 6,000 lbs. TWC + OC TWC 97000 5. 9L 6,000 lbs. TWC + OC oC 97000 5.91 6,000 lbs. Car Sound intends to market the new TWC + OC 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—1I1I). 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 Regulations, Section 2222(h) for the stated application. III. RECOMMENDATION Staff recommends that the exemption be granted as requested and that Executive Order No. D—193—18 be issued, permitting the advertisement, sale, and installation of the new aftermarket catalyst on applicable vehicles. Iv. ' DEVICE DESCRIPTION Car Sound‘s new aftermarket TWC + 0C is designed to use oval ceramic monolith substrates. The front and rear substrates are coated with palladium and rhodium in 5:1 ratio. Each substrate measures 4.75 inches along the major axis, 3.15 inches along the minor axis, and.1.93 inches in length, and has a volume of 24.6 cubic inches. Alumina coating was used as the washcoat for the catalyst. The substrates are contained in outer 409 stainless steel shell with Fiberfrax XPE paper

or 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 hgat 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 diréct contact with the catalyst shell. The catalyst may be sold as a unit with installation instructions or may be used in customized direct fit exhaust application. 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, and the end pipes. v. DEVICE EVALUATION Car Sound submitted data from testing conducted by Automotive Testing and Development Services (ATDS), Ontario, California. The test catalysts were aged by AlliedSsignal Environmental Catalyst using their ARL—102 ("RAT B") bench—aging cycle for 53 hours. The test catalysts were shipped directly to ATDS where the emissions tests were conducted for three—way plus oxidation (TWC + OC) application using a 1989 Dodge B250 Cargo Van 5.9L at the equivalent test weight (ETW) of 6,000 lbs. Three—way {TWC) application tests were conducted on a 1994 Dodge Ram 2500 Pickup Truck 5.9L at its certification ETW of 7,500 lbs. The oxidation catalyst application tests were conducted on a 1988 Dodge B350 Van 5.9L at the RTW of 6,000 lbs. Although Car Sound elected to conduct the TWC application test at the ETW of 7,500 lbs., they were informed, prior to start of testing that the TWC application will still be limited to $.9L/6,000 lbs., the limits to which the catalyst was aged. The test vehicles for TWC + OC and OC applications were ballasted in order to achieve the required ETW of 6,000 | pounds. The test catalysts were labeled as 94AM4 and S4AA5. 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 test results for the catalyst are shown below: ATDS, Ontario, California TWC + 0C Simulator Cat I4AA4 Cat Y4AA5 Conv. Eff. Average Average Average ~_— Average #C (g/mi) 2.758 0.546 0 .548 80.1% cCO (g/mi) 36.022 8.816 8.588 75.8% NOx (g/mi) 2.884 1.012 0.910 66.6% j TWC HC (g/mi) 2.324 0.332 0.332 10 85.7% co (g/mi) 26.474 5.151 4.029 82.6% NOx (g/mi) 6.308 1.182 0.894 83.5% oc HC (g/mi) 3.028 0.636 0.671 78. 4% co (g/mi) 27.020 4.292 5.068 82.6% ~2~

The above catalyst duplicates Car Sound‘s series 94000 TWC + OC, which was manufactured and bench—aged by Johnson Matthey. However, series 97000 is manufactured with only one half the loading of platinum on series 94000. Although the above test results show that series 97000 meet the minimum requirements of the California regulations on new aftermarket catalytic converters, the ARB wants to further investigate whether the performance of the catalyst was solely influenced by the washcoat technology used by AlliedSignal. For this reason, the ARB has requested Car Sound to conduct further testing in order to determine the role of the bench—aging cycle. Due to time constraints, the ARB was unable to conduct confirmatory testing on the new series 97000 TWC + Oc.
