      aftermarket three—way plus oxidation (TWC + OC) catalytic converter for fuel

      injected vehicle applications up to 5.8L engine size and 5,500 lbs. vehicle

      weight, under the California regulations for new aftermarket catalytic

      converters.

              Emissions data submitted show that the catalytic converter meets the

        I.         INTRODUCTION

                  Walker Manufacturing (Walker) of 3901 Willis Road, P.O. Box 157,

        Grass Lake, Michigan 49240 has applied for an exemption for their new

        aftermarket three—way plus oxidation (TWC + OC) catalytic converter for fuel

        injected vehicles up to 5.8L engine size and 5,500 lbs. vehicle weight.           The

        converter part numbers are shown below:




        Converter Type              Universal Part No.             Direct—Fit Part No.

        TWC + OC                 15140, 15141, 15142, 15143        15546, 15575, 15577

        II.        CcONCLUSION


                   The applicant has submitted all the required information and based
wn°m,




        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 Reqgulations, 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—182—8 be issued, permitting the advertisement,

        sale and installation of the new aftermarket catalytic converter.

        IV.        DEVICE_ DESCRIPTION

                   The Walker three—way plus oxidation catalyst uses ceramic monolithi&

        substrates which are coated with palladium and rhodium.           The substrates are

        enclosed in an outer stainless steel shell.           Heat shields are welded on top

        and bottom of the converter shell.        The catalytic converter is sold with

        installation instructions and kits as shown in the application catalog.
Lsns


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

          Walker has submitted the test data on the catalytic converter. The

emission tests were conducted by Automotive Testing and Development

Services, Inc.    (ATDS), Huntington Beach, California.     Testing consist of two

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

then two CVS—75 tests with exhaust backpressure simulator.        The two test

catalytic converters were previously aged using two 1990 fuel injected Ford

FP—250 trucks with 5.8L engine displacement, and 5500 l1b. vehicle test

weight.     The carry—over emission test vehicle was a 1992 TBI Dodge Ram B350,

5.9L and 5,500 lbs vehicle test weight.      The test results and conversion

efficiencies for the converter are shown below:




                 Simulator    Cconverter 1    Converter 2     Avgq.   Conv.   Eff.

HC (g/mi)         2.451         0. 427          0.356             84.0%
co (g/mi)        45.502         7.207           6.361             85.1%
NOx(g/mi}         3.034         1.253           1.293             58.0%
All of the conversion efficiencies meet the requirements of the California

reqgulations.    The staff based the evaluation of the new aftermarket

catalytic converter on the information submitted by Walker and on test data

from ATDS.
