    prohibitions in Vehicle Code Sections 27156 and 38§391, to allow the use of

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

    converter as an oxidation converter for vehicle applications up to 7.4L

    engine size and 5,500 lbs. vehicle test weight, in accordance with

    California reqgulations for new aftermarket catalytic converters.

            Emissions data submitted show that the catalytic converter meets the

    requirements of Vehicle Code Sections 27156 and 38391,   and Title 13,

         EVALUATION OF WALKER MANUFACTURING NEW AFTERMARKET OXIDATION
          CATALYTIC CONVERTER FOR EXEMPTION FROM THE PROHIBITIONS IN
             VEHICLE CODE SECTIONS 27156 AND 38391, AND TITLE 13,

I.         INTRODUCTION

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

Grass Lake, Michigan 49240 has applied for an exemption from the

prohibitions in Vehicle Code Sections 27156 and 38391 to allow the use of

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

converter for oxidation application on vehicles up to 7.4L engine size and

5,500 lbs. vehicle test weight, in accordance with California reqgulations on

new aftermarket catalytic converters.     The converter part numbers are shown

below:

TWC + OC                oC      15555, 15558, 15561   15144, 15145, 15146,   15147

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—182—9 be issued, permitting the advertisement,

sale and installation of the new aftermarket catalytic converter.

IV.      DEVICE DESCRIPTION

           Ceramic monolithic substrates which are coated with palladium and

rhodium is used in the manufacture of the three—way plus oxidation catalyst.

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.      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 Milton Roy Company (Milton Roy) in Orange,

California.     Two CVS—75 emission tests were conducted with the converter

installed,    followed by two CVS—75 tests with exhaust backpressure simulator.

The two test catalytic converters were previously aged using a 1976 Pohtiac

Station Wagon, and a 1975 Buick Electra, both powered by a 7,4L carbureted

engine.     The vehicle test weight used for the mileage accumulation was 5,500

lbs.   The carry—over emission test vehicle was a 1975 Buick Riviera powered

by a 7.4L carbureted engine using a test weight of 5,500 lbs.     The test

results and conversion efficiencies for the converter are shown below:




                 Simulator    Converter 1    Converter 2    Avg. Conv. Eff.

HC (g/mi)         2.778         0.608          0.535           79 .4%

co (g/mi)        10.782          1.554         1.635           85.2%

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 Walker and on test data

from Milton Roy.
