                                  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.

  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 cond´Čücted 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:

             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.
