 EVALUATION OF CAR SOUND EXHAUST SYSTEM, INC. NEW AFTERMARKET 24000 SERIES
    3—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

           Car Sound Exhaust System,      Inc.   (Car Sofind)   of 22961 Arroyo Vista,

Rancho Santa Margarita, California 92688, has applied for an exemption

to use their new aftermarket three—way plus oxidation (TWC + OC) catalytic

converter series 24000 (200HD)         for 3—way (TWC) application in accordance

with California regulations on new aftermarket catalytic converters.                 The

intended application for the new aftermarket catalytic converter is shown

below:

Type                      Series No.      Max. Engine Size           Max. Veh. Wt.

TwC                       24000             5.0L (305 CID)             4250 lbs.

The catalyst was re—canned as 200HD series from two separately aged

converters using two reducing substrates and one oxidizing substrate in

order to meet California‘s more stringent minimum conversion efficiency for

NOx.     Car Sound has changed their part number system and the 200HD series is

now called the 24000 series.

II.       CONCLUSION

          The applicant has submitted all the required information and based

on the submitted exhaust emissions test data,          the staff concludes that the

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.

III.      RECOMMENDATION
          The staff recommends that the exemption be granted as requested and

that Executive Order No. D—193—8 be issued,          permitting the advertisement,

sale and installation of the new 3—way aftermarket catalytic converter.


IV.        DEVICE DESCRIPTION

           The substrates of Car Sound‘s three—way substrates are coated with

palladium and rhodium without air injection incorporated between the

reducing and oxidizing substrates as was the case with the three—way plus

oxidation application.     The 24000 series converter was assembled with two

reducing and one oxidizing substrates enclosed in an outer stainless steel

shell.     A heat shield of aluminum is welded to the converter shell to

protect the vehicle underbody from heat.       The catalytic converter is sold as

a unit with installation instructions and kits as shown in the application

catalog.     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.

v.         DEVICE EVALUATION

           Car Sound has submitted test data on the 24000 catalytic converter.

The tests were conducted by Automotive Testing and Development Services,

Inc.   (ATDS), Huntington Beach, California.    The two reducing substrates and

one oxidizing substrate used to build the 24000 series converter were

previously aged on a 1984 and a 1985 carbureted Chevrolet Caprice 5.0L

closed—loop vehicles.    CVS—75 emission tests for the 3—way application were

conducted on a 1991 TBI Chevrolet Caprice 5.0L,     alternatively with the

converter and exhaust backpressure simulator installed in order to determine

the conversion efficiencies for HC, CO, and NOx.      The vehicle test weight

for the 24000 converter was 4,250 lbs.     The exemption for the 3—way

application is limited to vehicles powered by engine size up to 5.0L and

4250 lbs. vehicle weight, in order to conform to the "worst case"

requirement of the California regulations.


Car Sound also submitted a temperature profile which was conducted at ATDS

to demonstrate that stress produced on the catalyst by a carbureted 1985

Chevrolet Caprice, 5.0L with closed—loop TWC + 0C is equal to the stress

produced by a 1991 TBI Chevrolet Caprice, 5.0L with closed—loop TWC system.

The equivalent test weight for both vehicles was 4250 1b.        The temperature

profile did not show a significant difference between the stress produced by

the 1985 Chevrolet Caprice and the 1991 version.        The test results and

conversion efficiencies for the converter are shown below:




                                 24000 Series TWC

            Simulator   Test l   Test 2   Average Conv. Eff.

HC (g/mi)      2.463    o.258    0.384          87.0%
co (g/mi)   12.917      2.036    2.695          81.6%
Nox(g/mi)      3.316    o.582    0.494          83.8%
All of the conversion efficiencies meet the requirements of the California

regulations.    The staff based the evaluation of the new aftermarket

catalytic converter on the information submitted by Car Sound, and test data

from Automotive Testing and Development Services, Inc.
