State of California AIR RESOURCES BOARD EVALUATION OF TRI—D NEW AFTERMARKET TD—6000 CATALYTIC CONVERTER FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 AND TITLE 13, CALIFORNIA CODE OF REGULATIONS, SECTION 2222(h) March, 1989

EVALUATION OF TRI—D NEW AFTERMARKET TD—6000 CATALYTIC CONVERTER FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 AND TITLE 13, CALIFORNIA CODE OF REGULATIONS, SECTION 2222(h) by Mobile Source Division State of California AIR RESOURCES BOARD 9528 Telstar Avenue E1 Monte, CA 91731 (This report has been reviewed by the staff of the California Air Resources Board and approved for publication. Approval does not signify that the contents necessarily reflect the views and policies of the Air Resources Board, nor does mention of trade names or commercial products constitute endorsement or recommendation for use.)

SUMMARY TRI—D Automotive Inc. of Port Clinton, Ohio, has applied for exemption on their new aftermarket TD—6000 catalytic converter under the California Evaluation Procedures for New Aftermarket Non—Original Equipment Catalytic Converters. The TD—6000 converter is to be used as three—way converter on 3.8 liter vehicles up to 3750 lbs, and as three—way plus oxidation on 5.7 liter vehicles up to 4000 lbs. The California regulations require conversion efficiencies of 70% for HC and CO, 60% for NOx on three— way converters and 50% for three—way plus oxidation new aftermarket catalytic converters. Emissions data submitted show that the TRI—D TD—6000 catalytic converter meets the requirements of Vehicle Code Section 27156 and 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.

EVALUATION OF TRI—D NEW AFTERMARKET TD—6000 CATALYTIC CONVERTER FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 AND TITLE 13, CALIFORNIA CODE OF REGULATIONS, SECTION 2222(h) I. INTRODUCTION TRI—D Automotive Inc. of Port Clinton, Ohio, has applied for an exemption for their new aftermarket TD—6000 catalytic converter in accordance with the new California regulations on new aftermarket catalytic converters. The TD—6000 is designed for dual applications; as three—way converter on 3.8 liter vehicles with weight not exceeding 3750 lbs, and as three—way plus oxidation on 5.7 liter vehicles with weight not exceeding 4000 lbs. The secondary air injection tube is permanently welded closed when the TD—6000 is used for three—way application. II. CONCL N The applicant has submitted all the required information and based on the submitted exhaust emissions test data, the staff concludes that the TD—6000 catalytic converter meets the criteria set forth in Vehicle Code Section 27156 and Title 13, California Code of Regulations, Section 2222(h). III. RECOMMENDATION The staff recommends that the exemption be granted as requested and that Executive Order No. D~188 permitting the advertisement, sale and installation of the new aftermarket catalytic converter be issued. IV. VICE DESCRIPTION The TRI—D catalytic converter consists of honeycomb type substrates coated with palladium and rhodium enclosed in an outer shell or container of stainless steel. The TRI—D Automotive Inc. catalytic converter uses materials and construction similar to the original equipment manufacturers.

The catalytic converter is sold with installation instructions and kits as shown in the application catalog. It is also sold with a two year or 25,000 mile warranty on the substrates and five years or 50,000 miles on the container or shell. ¥. DEVICE EVALUATION TRI—D Automotive Inc. provided test data on the catalytic converter. The tests on the TD—6000 converter were conducted by DMACS Engineering Laboratories, Inc., Telford, Pennsylvania. For the three—way application, two catalytic converters were respectively aged on two 1987 Chevrolet Camaro IROC—Z, both having engine displacement of 5.7 liters. The FTP tests of the converters were conducted on a 1988 Oldsmobile Delta 88 with 3.8 liter engine and 3750 test weight. The test results are shown below: Converter Test Typ. HC cCO NOx Simulator FTP 1.435 8.822 2.459 TDMOL FTP 0.189 1.293 0.755 TDMO2 FTP 0.196 1.162 0.733 Efficiency HC co NOx TDMO1 86.83 85. 34 69.30 TDMO2 86.34 86.83 70.19 AVERAGE : 86.59 86.09 69.75

The three—way plus oxidation catalytic converter was aged and tested on a 1987 Chevrolet IROC—Z, with 5.7 liter engine and a test weight of 4000 lbs. The results are shown below: Converter Test Typ. NOx Simulator FTP 2.383 27 .234 2.520 TDMOL FTP 0 .648 4.180 0 .840 TDMO2 FTP 0 .628 2.381 1.024 Efficiency HC co NOx TDMO1 72.80 84.65 66.66 TDMO2 73.65 91.25 59.37 AVERAGE : 73.23 87.95 63.02 All of the above conversion efficiencies meet the requirements of the California regulations which are 70% for HC and CO on all converter types, 60% for NOx on three—way and 50% for NOx on three—way plus oxidation converter. The staff based the evaluation of the new aftermarket TD—6000 converter on the data from DMACS Engineering Laboratories Inc. tests.
