Device Description: Car Sound‘s new aftermarket TWC is designed to use three oval ceramic monolith substrates. The substrates are coated with platinum and rhodium in the ratio of 2:1. The dimensions of the substrates are 5.70 inches for the major axis, 3.20 inches for the minor axis, and 2.93 inches in length. The volume of each substrate is 46.3 cubic inches. The substrates are contained in a shell constructed from 409—grade stainless steel. The substrates are wrapped with a Fiberfrax XPE Expanding Paper, to prevent vibration and exhaust by—pass. The shell is sealed by seam weld, and a piece of aluminized heat shield is spot—welded to the upper side of the converter to protect the vehicle underbody from excessive heat. The catalytic converter will be sold as a universal fit with installation instructions. It comes 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. AlliedSignal Environmental Catalyst (ASEC) of Tulsa, Oklahoma, is the catalyst supplier for Car Sound‘s series 95500 TWC.

Discussion/Basis for Exemption Recommendation: Car Sound submitted data on the series 95500 TWC from testing conducted at Automotive Testing and Development Services (ATDS) laboratory, Ontario, California. ASEC performed the catalyst rapid aging using its ARL—102 for 90 hours. Emission tests were conducted on a 1991 Chevrolet 7.4L 3500HD long bed pickup truck. An additional load of 440 pounds (Ibs.) was added to the vehicle to bring the equivalent test weight to 13,000 Ibs. as desired by the applicant. The evaluation of the new aftermarket catalytic converter is solely based on the bench—aging by ASEC and emission tests conducted at ATDS. The limits of application of Car Sound‘s series 95500 TWC will be 7.4L/13,000 lbs., with the corresponding maximum gross vehicle weight rating (GVWR) of 15,620 Ibs. The test catalysts were labeled T1020 A1 and T1020 AZ2. Testing consisted of two cold—start CVS—75 tests with a simulator {"dummy" catalyst), followed by two cold—start CVS—75 tests 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 series 95500 catalyst are shown below: ATDS, Ontario. California Simulator Catalyst 711020 M Catalyst 71020 A2 Conv. Fff. Average Average Average Average TWG HC (g/mi) 3.155 0.653 0.637 79.6% CO (g/mi) 52.950 14.092 14.975 72.6% NOx (g/mi) 8.302 1.980 1.870 76.8% The above test results meet the minimum requirements of the California regulations on new aftermarket catalytic converters. The Air Resources Board (ARB) did not conduct confirmatory tests on the new aftermarket catalytic converter.
