    FOR EXEMPTION FROM THE PROHIBITIONSOF VEHICLE CODE SECTION 27156
       AND TITLE 13, CALIFORNIA CODE OF REGULATIONS, SECTION 2222(h)


I.      INTRODUCTION
        Maremont Corporation (Maremont) of 250 E. Kehoe Blvd, Carol Stream,

Illinois 60188, has applied for an exemption for their new aftermarket

three—way (TWC) catalytic converter in accordance with the California

regulations on new aftermarket catalytic converters.     The intended converter

application is shown below:

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

TWC                    28802,28833,    5.71 (350 CID)         6000 1bs.

                       28834



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—184—6 be issued, permitting the advertisement,

sale and installation of the new aftermarket catalytic converter.


IV.        DEVICE DESCRIPTION

           The Maremont three—way substrates are coated with palladium and

rhodium.    Air injection is not incorporated between the reducing and

oxidizing substrates.     The substrates are enclosed in an outer shell or

container of stainless steel.     The converter shell is constructed of

stainless steel 409.     A heat shield of aluminum is welded to the converter

shell to protect the vehicle underbody from heat.     The catalytic converter

is sold with installation instructions and kits as shown in the Maremont‘s

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

           Maremont has submitted test data on the catalytic converter.     The

tests were conducted by Automotive Testing and Development Services, Inc.

(ATDS), Huntington Beach, California.     The two test catalysts were

respectively aged on a 1988 Chevrolet Suburban, 5.7L with TBI (Throttle Body

Injection), and a 1988 Chevrolet Silverado Pick—up, 5.7L with TBI.        The

conversion efficiency testing was conducted on a 1988 Chevrolet Cheyenne,

5.7L with TBI as a test vehicle.     Two CVS—75 emission tests were conducted

on the test vehicle with the converter installed and two CVS—75 tests were

conducted with exhaust backpressure simulator.     The vehicle test weight for

all three vehicles was 6000 Tbs.    The exemption for the converter is limited

to vehicles up to 5.7 liters and 6000 lbs.    in order to conform to the "worst

case" requirement of the California regulations.     The test results and

conversion efficiencies for the converter are shown below:

CO (g/mi)    20.024          5.048               4.130          75.6%

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 Maremont and on test

data from Automotive Testing and Development Services, Inc.
