      1.     No changes are permitted to the catalytic converter as described in the
             application for exemption. Any changes to the catalytic converter or any of its
             components, and otherfactors addressed in this order must be evaluated and
             approved by the ARB prior to marketing in California.

             Marketing of the catalytic converter using identifications other than those shown
             in the exemption application, and in this Executive Order, or marketing of the
             catalytic converter for an application other than the ones shown in this Executive .
             Order shall be prohibited unless prior approval is obtained from the ARB.
             Exemption of this product shall not be construed as an exemption to sell, offer
             for sale, or advertise any components of the catalytic converter as individual
             devices.

                                           SUMMARY


             Walker Manufacturing Company (Walker), a division of Tenneco Automotive, of

2701 North Dettman Road, Jackson, Michigan 49201 has applied for an exemption of its series

99000 new aftermarket three—way plus oxidation catalytic converter (TWC + OC) from the

prohibitions in Vehicle Code Section 27156, in accordance with California regulations for new

aftermarket catalytic converters. The catalytic converter is manufactured in two different oval

configurations and one round configuration. The two converters with oval configuration contain

two substrates and are designed for TWC + OC and three—way catalytic converter (TWC)

applications. The converter with the round configuration contains a single substrate and is

designed for TWC application. Three test catalysts were aged using AlliedSignal Environmental

Catalyst‘s (ASEC‘s) rapid aging cycle ARL—102 for a duration of 53 hours, based on

temperature histogram data collected by ASEC. The substrates are of ceramic monolith type

and are coated with platinum and rhodium in a 2:1 ratio. The emission tests were conducted on

a 1989 Dodge Ram‘ Van 5.9L, equipped with a TWC + OC, at the equi'valent test weight of

7,000 pounds (Ibs.), and a 1995 Dodge Ram Truck, equipped with a TWC, at an equivalent test

weight of 6,000 Ibs. The new catalytic converter is for installation on vehicies equipped with

TWC + OC or TWC. The maximum application limits for the new series 99000 catalytic

converter are 5.9L and 6,000 lbs., which corresponds to 5.9L engine displacement and gross

vehicle weight of 7,500 lbs.

            Emissions data submitted by the applicant show that the catalytic converter meets

the requirements of Vehicle Code Section 27156 énd Title 13, California Code of Regulations,

Section 2222(h) for the stated applications. Based on the above, the staff recommends that the

exemption be granted as requested and that Executive Order D—182—28 be issued.

1.          INTRODUCTION

            Walker Manufacturing Company (Walker) of 2701 North Dettman Road, Jackson,

Michigan 49201, has applied for an exemption from the prohibitions in Vehicle Code Section

27156 for its series 99000 new aftermarket three—way plus oxidation catalytic converter (TWC +

OC) in accordance with California regulations for new aftermarket catalytic converters. The new

aftermarket catalytic converter is intended for the following vehicle applications:

The maximum Gross Vehicle Weight (GVW) forthe catalytic converter application is 7,500 Ibs.

Walker intends to market the-new converter as a replacement for catalytic convérters on in—use

vehicles whose manufacturer‘s warranty has expired and the need for replacement of the

original equipment manufacturer (OEM) catalytic converter has been estabiished and

documented. The converter cannot be installed on vehicles equipped with an On—Board

Diagnostic II (OBD—II) system.

II.         CONCLUSION

            The applicant has submitted all the required information, and based on the

applicant‘s submitted exhaust emissions test data, the staff concludes that the new aftermarket

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 applications.


IIl.           RECOMMENDATION

               Staff recommends that the exemption be granted as requested and that Executive

Order No. D—182—28 be issued, permitting the advertisement, sale, and installation of the new

aftermarket catalytic converter on applicable vehicles.

IV.        _   DEVICE DESCRIPTION
               Walker‘s series 99000 new aftermarket catalytic converter is designed to use

ceramic monolith substrates with three different dimensions and two different shapes. The

minor and major axis of the two oval shaped substrates are 3.15 inches and 4.75 inches, and

3.2 inches and 5.7 inches, respectively. The oval substrates are both 1.90 inches in length.

The round substrate is 3.66 inches in diameter and 5.00 inches in length.     The substrates are

coated with platinum and rhodium in a 2:1 ratio. Two substrates are assembled per can for the

oval shaped converter with the total volume of 48.8 cubic inches and 58.8 cubic inches,

respectively. The round converter contains a single substrate with a volume of 52.6 cubic

inches. The substrates are contained in an outer 409 stainless steel shell with compressed

intumescent or expanding mat to pre\;ent vibration and exhaust by—pass. The shell halvés are

sealed by seam weld, and the end pipes are attached to the shell by are welding. An

aluminized heat shield is spot—welded to the upper side of the converter to protect the venicie

from excessive heat. The catalytic converter is sold as a unit with installation instructions or

used in customized direct fit exhaust.applications. It is sold with a warranty for 25,000 miles on

the substrate, and five years or 50,000 miles on the container or shell, and the end pipes.

V.     C       DEVICE EVALUATION

               Walker submitted data from testing conducted by Automotive Testing and

Development Services (ATDS) laboratory located in Ontario, California. Catalyst bench—aging

was conducted by the catalyst supplier, AlliedSignal Environmental Catalyst (ASEC) using its

                                                —9.


ARL—102 rapid—aging. The aging duration of 53 hours was calculated from temperature

histogram data obtained from vehicles similar to the ones used in emission testing. The 53—

hour aging duration was determined to produce aging severity similar to that which the catalyst

would experience when aged on the road for 25,000 miles using the AMA driving cycle.

Emissions tests were conducted on a 1989 Dodge Ram Van 5.9L equipped with a TWC + OC,

and a 1995 Dodge Ram 2500 Truck 5.9L equipped with a TWC.

             The evaluation of Walker‘s new aftermarket catalytic converter is solely based on

the bench—aging conducted by ASEC and the emission tests conducted at ATDS. The limits of

application of Walker‘s series 99000 TWC are 5.91/6,000 lbs. with a corresponding maximum

gross vehicle weight of 7,500 lbs. The six test catalysts were labeled WOO—181, WOO—182,

WOO—190, WOO0—191, WOO0—193, and WOO—194 respectively. Testing consisted of two cold—start

CVS—75 tests with a simulator ("dummy" catalyst), followed by two cold—start CV S—75 tests for

each of the test catalysts. The average of the two test results for each test catalyst was used to

calculate the conversion efficiency. The overall conversion efficiency for the catalyst model is

the average conversion efficiency of the three'test catalysts. The test results for the catalyst

are shown below:

The overall conversion efficiencies fdr the catalytic converter are 83.6 percent, 83.6 percent,

and 78.1 percent for HC, CO, and NOx, respectively. The conversion efficiencies of the three

different configurations of the catalytic converter each meet the minimum requirements of the

California regulations for new aftermarket catalytic converters. The ARB did not conduct

confirmatory testing on the catalysts.
