                                  SUMMARY

       Maremont Corporation has applied for an exemption for their new

aftermarket oxidation catalytic converter part nos. 28706 and 28735, for

exemption from the prohibitions of Vehicle Code Section 27156, and Title 13,

Section 2222 of the California Code of Regulations.     Maremont Corporation

plans to use the new aftermarket catalytic converters on vehicles with a

maximum engine size and weight of 460 CID (7.5 L) and 6,000 Ibs.,

respectively.

       Maremont Corporation has submitted emission test data to demonstrate

that the catalytic converters meet the requirements of the California

regulations for new aftermarket catalytic converters.     Based on submitted

emission test data, the staff recommends that the exemption be granted as

requested.

                    EVALUATION OF MAREMONT CORPORATION‘S
     NEW AFTERMARKET OXIDATION CATALYTIC CONVERTERS FOR EXEMPTION FROM
     THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH
       TITLE 13, SECTION 2222, OF THE CALIFORNIA CODE OF REGULATIONS



I.   INTRODUCTION

        Maremont Corporation of 250 E. Kehoe Blvd., Carol Stream, IL 60188,

has applied for an exemption for their new aftermarket oxidation catalytic

converter part nos. 28706 and 28735, in accordance with the California

regulations on new aftermarket catalytic converters.   The catalytic

converter part no. 28706 is for vehicles with engine displacement up to

460 CID (7.5 L) and maximum equivalent test weight of 6,000 lbs.   Part no.

28735 is intended for 1982 to 1986 Chevrolet and GMC light—duty trucks with

engine sizes up to 460 CID (7.5 L).



II. CONCLUSION

        Based on submitted exhaust emissions test data, the staff concludes

that the catalytic converters meet the criteria set forth in Vehicle Code

Section 27156 and Title 13, California Code of Regulations, Section 2222(h)

for the stated application.



III. RECOMMENDATIONS

        The staff recommends that Maremont be granted an exemption for their

catalytic converter part nos. 28706 and 28735 as requested, and that

Executive Order No. D—184—7 be issued, permitting the advertisement, sale

and installation of the new aftermarket catalytic converters.


IV. DEVICE DESCRIPTION

       The outer shell of Maremont‘s catalytic converters is constructed of

0.054 min. SAE 51409 stainless steel.       The substrate consists of a

monolithic, extruded honeycomb material, made of cordierite, mullite,

alumina, and spinel.     The dimensions of the honeycomb material are 5.7 x 3.2

x 2.96 inches with a total volume of 45.86 cubic inches.       The active

material in the honeycomb is Palladium mixed with Lanthanide Oxide coating

and stabilizers.   The catalytic converter has a total volume of 180 cubic

inches, and weighs 8.5 lbs.     A heat shield of 0.032 min. aluminized steel is

welded to the converter shell to protect the vehicle underbody from heat.

The device is sold with a warranty for 25,000 miles on the substrate, and

five years or 50,000 miles on the shell.       An installation manual is also

enclosed in the sale kit.



v. DISCUSSION
       Maremont has submitted test data on the catalytic converters

conducted by Automotive Testing and Development Services, Inc., 15442

Chemical Lane, Huntington Beach, California.       The two test catalysts were

aged on two 1979 Ford F—250 pick—ups (test vehicle nos. 167—1 and 167—2),

each with an engine size of 460 CID (7.5 L).       The conversion efficiency

tests were conducted on a third vehicle (test vehicle no. 167—3) with the

same configuration as the other two mileage accumulation vehicles.          The test

weight for all three vehicles was 6,000 lbs.

       Conversion efficiency tests on the two aged catalytic converters

consisted of two CVS—75 emission tests with the aged catalytic converter

installed on the slave test vehicle, and two CVS—75 tests with exhaust back—

pressure simulator installed.    The test results and conversion efficiencies

                                      _2—


for the converters are given in Table 1.

       Based on the information submitted by Maremont Corporation and the

test data from Automotive Testing and Development Services, Inc., the staff

concluded that catalytic converter part nos. 28706 and 28735, meet the

requirements of the California regulations.           The staff recommends that

Maremont Corporation be granted an exemption as requested.
