Santa Margarita, California 92688 has applied for an exemption of its series 53000 new

aftermarket three—way catalytic converter (TWC) from the prohibitions in Vehicle Code Section

27156, in accordance with California regulations for new aftermarket catalytic converters. The

catalytic converter is manutactured in a round configuration. The two test catalysts were aged

using Johnson Matthey‘s rapid aging cycle, EDC—53, which has been accepted by the Air

Resources Board for aging catal;/sts designed for vehicle application limits of 5.9L/6,000 lbs.

The new TWC has a single substrate of ceramic monolith type and coated with platinum and

rhodium in é 4:1 ratio. The emission tests were conducted on a 1994 Jeep Grand Cherokee

4.0L, equipped with a TWC, at the equivalent test weight of 4,250 pounds (Ibs.). The new

catalytic converter is for installation on vehicles equipped with a single TWC. Thé maximum

application limits for the new series 53000 TWC are 4.0L and 4,250 lbs., which corresponds to

4.0L engine displacement and gross vehicle weight rating of 4550 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 applications. Based on the above, the staff recommends that the

exemption be granted as requested and that Executive Order D—193—21 be issued.

California Code of Regulations, Section 2222(h) for the stated application.


 HL.           RECOMMENDATION

               Staff recommends that the exemption be granted as requested and that Executive

 Order No. D—193—21 be issued, permitting the advertisement, sale, and installation of the new

 aftermarket catalytic converter on applicable vehicles.

 IV.          DEVICE DESCRIPTION

              Car Sound‘s series 53000 new aftermarket catalytic converter is designed to use a

 single round~shéped ceramic monolith substrate. The substrate is $.66 inches in diameter and

 2.93 inches in length. The substrate volume is 30.8 cubic inches. The substrate is coated with

 platinum and rhodium in a 4:1 rajtio, The substrate is contained in an outer 409 stainless steel

 shell with compressed intumescent or expanding mat to prevent vibration and exhaust by—pass.

 The shell haives are sealed by seam weld, and the end pipes are attached to the shell by arc

 welding. An éluminized heat shield is spot—wéjded to the upper side of the converter to protect

 the vehicle frdm excessive heat. The catalytic converter is _sold as a unit with installation

 instructions or 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

              Car Sound submitted data frorfi testing conducted by California Environmental

_ Engineering (CEE) laboratory located in Santa Ana, California. Catalyst bench—aging was

conducted by the catalyst supplier, Johnson Matthey using its bench—aging cycle EDC—53.

 Emissions tests were conducted on a 1994 Jeep Grand Cherokee 4.0L equipped with a TWC,

at the equivalent test weight of 4,250 lbs.

              The evaluation of Car Sound‘s new aftermarket catalytic converter is based on the

bench—aging conducted by 'Johnson Matthey and the emission tests conducted at CEE.
