SUMMARY Engelhard Corporation (Engelhard) of 101 Wood Avenue, Iselin, New Jersey 08830—0770 has applied for an exemption from the prohibitions of Section 27156 of the California Vehicle Code for their CMX Catalytic Converter Muffler and CCX Catalytic Converter (CMX/CCX). The CMX/CCX converter is designed for installation on 1990 and older model—year heavy— duty two—stroke diesel—powered engines and has been certified by the United States Environmental Protection Agency to meet their requirements for the Urban Bus Retrofit and Rebuild Program. Emissions data obtained from heavy—duty transient Federal Test Procedure show that the CMX/CCX converter meets the requirements of Section 27156 of the California Vehicle Code and Section 2222, Title 13 of the California Code of Regulations and will not adversely affect the emissions from those engines for which the exemption is requested. The staff recommends that Engelhard be granted an exemption as requested and that Executive Order No. D—384 be issued.

State of California AIR RESOURCES BOARD EVALUATION OF ENGELHARD CORPORATION‘S CMX CATALYTIC CONVERTER MUFFLER AND CCX CATALYTIC CONVERTER FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13 OF THE CALIFORNIA CODE OF REGULATIONS . I. INTRODUCTION Engelhard Corporation (Engelhard) of 101 Wood Avenue, Iselin, New Jersey 08830—0770 has applied for an exemption from the prohibitions of Section 27156 of the California Vehicle Code for their CMX Catalytic Converter Mufflier and CCX Catalytic Converter (CMX/CCX) for installation on 1990 and older model—year heavy—duty two—stroke diesel—powered engines. Engethard has submitted the results from heavy—duty transient Federal Test Procedure conducted on a 1985 model—year Detroit Diesel Corporation (DDC) 6V—92TA Mechanical Unit Injection (MUI) engine. I1. CONCLUS ION Engelhard has submitted all the required information, and based on the submitted emissions test data, the staff concludes that CMX/CCX converter does not adversely affect the exhaust emissions from those engines for which the exemption is requested. III. RECOMMENDATION . The staff recommends that Engelhard be granted an exemption as requested, permitting advertisement, sale and installation of their CMX/CCX converter on 1990 and older model—year heavy—duty two—stroke diesel—powered = engines, and that Executive Order No. D—384 be issued.

IV. DEVICE DESCRIPTION AND OPERATION The CMX converter is an integrated catalytic converter muffler designed to replace the originél equipment manufacturer muffler. It provides particulate matter emission reduction as well as exhaust noise attenuation. The CCX converter is a converter—only add—on device. Centerbodies of both the CMX and CCX converters are identical.in their physical and chemical characteristics. The CMX/CCX converter consists of ceramic monolithic substrates coated with platinum catalyst. All CMX/CCX converter shells are made of 459 stainless steel with the exception of the aluminized steel shell used for the Flxible bus configuration. The CMX/CCX converter shells measure from 9 to 12 inches in diameter and from 18 to 43 inches in length. Engelhard provides different installation kits with the CMX/CCX converters to fit the various two—stroke engines. . DEVICE EVALUATION AND DISCUSSION Engelhard has submitted results of emissions testing conducted at Southwest Research Institute located in San Antonio, Texas. The test engine was a federally—certified 1985 model—year DDC 6V—92TA MUI engine. The V—6, two-stroke'diesel-powered engine had a 552 cubic inches displacement and has accumulated approximately 300,000 miles of service. Emissions were measured over the heavy—duty transient Federal Test Procedure as set‘forth in Title 40 Part 86, Subpart N of the Code of Federal Regulations. One baseline transient emission test was condficted on the engine without the CMX/CCX converter. A modified transient emission test was conducted with the CMX/CCX converter installed. The emission test results from the transient tests are shown below:

Heavy—Duty Transient Federal Test Procedure Exhaust Emissions (g/bhp—hr)* HC co NOx PM Baseline: . Cold—Transtent 1.929 3.111 9.629 ‘ 1.673 Hot—Transient 1.079 2.449 9.540 0 .757 Composite** 1.200 2.544 9.553 0 .888 Modified: Cold—Transient 1.345 2.232 9.804 1.221 Hot—Transient 0.544 1.199 9.688 0.412 Composite** 0.658 1.347 9.705 0 .528 Difference Between Baseline and Modified: —0.542 ~1.197 +0 .152 —0 .360 % Difference: ~45.2% ~4]7 .1% +1.6% ~40.5% * grams per brake—horsepower—hour k* ?ne-§eventh of cold—transient level and six—seventh of hot—transient eve The differences between the modified and baseline test results submitted by Engelhard were within the allowed limits of 10 percent hydrocarbon (HC), 15 percent carbon monoxide (CO), 10 percent oxides of nitrogen (NOx), and 15 percent particulate matter (PM) as specified in the "Procedures for Exemption of Add—On and Modified Parts." Since the test engine used was federally—certified, the staff conducted an engineering evaluation of the CMX/CCX converter to determine its emissions impact on California—certified engines. The catalyst formulation submitted by Engethard indicates that NOx emissions will not be affected by the catalytic reaction. The emission test results on the federally—certified engine show that HC, CO, and PM emission tevels decrease with the use of the CMX/CCX converter while the NOx emission level is unaffected (the slight increase in NOx emission level is attributed to test—to—test variability). The staff believes that similar effect on

emissions will be exhibited if the CMX/CCX converter is used on California— certified engines. Therefore, the staff concludes that the CMX/CCX converter will not have any adverse effect on exhaust emissions of the engines for which an exemption is requested. Engelhard has submitted all the required information and has fulfilled the requirements for an exemption.
