                                            of the Vehicle Code

                                   DETROIT DIESEL CORPORATION
                                    DDEC ENGINE UPGRADE KIT


Pursuant to the authority vested in the Air Resources Board (ARB) by Section 27156 of the Vehicle
Code; and


Pursuant to the authority vested in the undersigned by Sections 39515 and 39516 of the Health and
Safety Code and Executive Order G—45—9;

IT IS ORDERED AND RESOLVED: That installation of the DDEC Engine Upgrade Kit,
manufactured by Detroit Diesel Corporation of 13400 Outer Drive, West, Detroit, Michigan
48239—4001, has been found not to reduce the effectiveness of the applicable vehicle pollution control
system, and therefore, the DDEC Engine Upgrade Kit is exempt from the prohibitions of Section
27156 of the Vehicle Code for installation on diesel—powered 1985—1990 model—year Detroit Diesel
Corporation (DDC) 6V92TA DDEC urban bus engines with power ratings of 253 and 277 horsepower.

The DDEC Engine Upgrade Kit rebuilds diesel—powered 1985—1990 model—year 6V92TA DDEC urban
bus engines to meet California‘s 1991 model—year heavy—duty diesel urban bus engine emission
standards of 0.10 grams per brake—horsepower—hour (g/bhp—hr) particulate matter (PM) and
5.0 g/bhp—hr oxides of nitrogen (NOx).

The required DDEC Engine Upgrade Kit parts are listed in the parts lists which are attached hereto and
incorporated herein.                                                                                 ‘

The DDEC Engine Upgrade Kit consists of three kits: 1) engine rebuild kit — newly manufactured
parts, 2) engine rebuild kit — reliabilt parts, and 3) converter/muffier kit. The newly manufactured
parts kit consists of a gasket kit, air inlet hose, blower drive gear (2.05 to 1), blower by—pass valve
assembly, cylinder kits (piston assemblies and cylinder liners), new electronic—unit fuel injectors, and
DDEC II to DDEC IfI conversion kits. The reliabilt parts kit consists of remanufactured camshafts,
blower assembly, turbocharger, and head assemblies. The converter/muffler kit consists of a direct—
replacement oxidation catalyst supplied by Nelson, Engine Control Systems, or Engelhard. One of
each type kit is required for the rebuild of an engine.

The DDEC Engine Upgrade Kit incorporates the revised certification word codes as required by the
United States Environmental Protection Agency as resolution of the NOx defeat device issue.


DETROIT DIESEL CORPORATION                                      EXECUTIVE ORDER D—202—1
DDEC ENGINE UPGRADE KIT                                         (Page 2 of 3)


This exemption is based on emission tests conducted by DDC on a federal 1993 model—year 6VIZTA
DDEC engine. DDC submitted the following federal transient heavy—duty diesel engine test results for
a 552 cubic—inch 6VIZTA DDEC engine with a 277 horsepower rating:

                Converter/                HC        CO        NO        PM
                Muffler                 (grams per brake horsepower—hour)

                A*                        0.3      1.0       4.8       0.08
                B*                        0.1      0.2       4.7       0.08
                C*                        0.2      0.5       4.9       0.10
                Emission Standard         1.3      15.5      5.0       0.10

                * The upgrade kit is available with converter/muffler kits from
                   three suppliers: Nelson, Engine Control Systems, and Engelhard.



The test data show that the DDEC Engine Upgrade Kit did not adversely affect the exhaust emissions
of the DDEC 6V92ZTA engine. The same emissions impact is expected when the DDEC Engine
Upgrade Kit is installed on the engines for which the exemption is requested.

This Executive Order is valid provided that installation instructions for the DDEC Engine Upgrade Kit
not recommend tuning the vehicle to specifications different from those submitted by the vehicle
manufacturer.

Changes made to the design or operating conditions of the DDEC Engine Upgrade Kit, as exempt by
the ARB, which adversely affect the performance of a vehicle‘s pollution control system shall
invalidate this Executive Order.

Marketing of the DDEC Engine Upgrade Kit using an identification other than that shown in this
Executive Order or for an applicationother than those listed in the attachments shall be prohibited
unless prior approval is obtained from the ARB.

In addition to the foregoing, the ARB reserves the right in the future to review this Executive Order
and the exemption provided herein to assure that the exempted DDEC Engine Upgrade Kit continues to
meet the standards and procedures of Title 13, California Code of Regulations, Section 2222 et seq.

This Executive Order does not constitute any opinion as to the effect the use of the DDEC Engine
Upgrade Kit may have on any warranty either expressed or implied by the vehicle manufacturer.

THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION,
APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD
OF CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY
ALLEGED BENEFITS OF DETROIT DIESEL CORPORATION‘S DDEC ENGINE UPGRADE
KIT.                   '

                                              SUMMARY


          Detroit Diesel Corporation (DDC) of 13400 QOuter Drive, West, Detroit, Michigan 48239—

4001 has applied for an exemption from the prohibitions of Section 27156 of the California Vehicle

Code for their DDEC Engine Upgrade Kit. DDC‘s upgrade kit is designed to rebuild diesel—powered

1985—1990 model—year 6VI2TA DDEC urban bus engines. With the upgrade kit, the engines meet

California‘s 1991 model—year heavy—duty diesel urban bus engine emission standards of 0.10 grams per

brake—horsepower—hour (g/bhp—hr) particulate matter (PM) and 5.0 g/bhp—hr oxides of nitrogen (NOx).

         Based on the test data submitted by DDC, staff concludes that the DDEC Engine Upgrade Kit

will not adversely affect the exhaust emissions of the engines for which the exemption is requested.

Therefore, staff recommends that DDC be granted an exemption for their upgrade kit as requested and

that Executive Order No. D—202—1 be issued.

L.        INTRODUCTION

          Detroit Diesel Corporation (DDC) of 13400 Outer Drive, West, Detroit, Michigan 48239—

4001 has applied for an exemption from the prohibitions of Section 27156 of the California Vehicle

Code for their DDEC Engine Upgrade Kit. The upgrade kit is designed for use on diesel—powered

1985—1990 model—year 6VOZTA DDEC urban bus engines. DDC has submitted all the required

information including engine upgrade parts list and emission test data.



IL.       CONCLUSION

          Based on the test data submitted by DDC, staff concludes that the engines rebuilt with the

upgrade kit meet California‘s 1991 model—year heavy—duty diesel urban bus engine emission standards

and will not adversely affect the emissions of the applicable engines.



HL.      RECOMMENDATION

         Staff recommends that DDC be granted an exemption as requested, permitting advertisement,

sale and installation of their upgrade kit on diesel—powered 1985—1990 model—year 6VIZTA DDEC

urban bus engines.




IV.      DEVICE      DESCRIPTION AND             ATION

         DDC has designed their kit to allow upgrade of diesel—powered 1985—1990 model—year

6VI2ZTA DDEC urban bus engines to meet the 1991 model—year heavy—duty diesel urban bus engine

                                                    1


 emission standards. The upgrade kit consists of three kits: 1) engine rebuild kit — newly manufactured

 parts, 2) engine rebuild kit — reliabilt parts, and 3) converter/muffler kit. The newly manufactured

 parts kit consists of a gasket kit, air inlet hose, blower drive gear (2.05 to 1), blower by—pass valve

 assembly, cylinder kits (piston assemblies and cylinder liners), new electronic—unit fuel injectors, and


 DDEC II to DDEC III conversion kits. The reliabilt parts kit consists of remanufactured camshafts,

 blower assembly, turbocharger, and head assemblies. The converter/muffier kit consists of a direct—

 replacement oxidation catalyst supplied by Nelson, Engine Control Systems, or Engelhard. One of

. each type kit is required for the rebuild of an engine. The upgrade kit incorporates the revised

 certification word codes as required by the United States Environmental Protection Agency (U.S.

 EPA) as resolution of the NOx defeat device issue.




 v.        DEVICE EVALUATION AND DISCUSSION

           To demonstrate that their upgrade kit does not adversely affectthe engines‘ exhaust

 emissions, DDC tested a federal 1993 model—year 6V92TA DDEC engine.             DDC submitted the

 following federal transient heavy—duty diesel engine test results for a 552 cubic—inch 6VI2TA DDEC

 engine with a 277 horsepower rating:

                 Converter/                HC         cCO       NO        PM
                 Muffler                 (grams per brake horsepower—hour)

                 A*                        0.3        1.0       4.8       0.08
                 B*                        0.1        0.2       4.7       0.08
                 C*                        0.2        0.5       4.9       0.10
                 Emission Standard         1.3        15.5      5.0       0.10

                 * The upgrade kit is available with converter/muffler kits from
                   three suppliers: Nelson, Engine Control Systems, and Engelhard.


        The test data show that the exhaust emissions of the modified engine were below the California

emission standards for 1991 model—year urban bus engines. Staff concludes that the upgrade kit does

not adversely affect the exhaust emissions of the DDEC 6V9ZTA engine, and the same emissions

impact is expected when the upgrade kit is installed on California—certified 1985—1990 model—year

6GV9I2TA DDEC engines.

        DDC also submitted emission data with the revised calibrations which were incorporated in the

upgrade kit as required by the U.S. EPA as resolution of the NOx defeat device issue. (The emission

data are contained in DDC‘s exemption application file.) The revised calibrations are only applicable

to the steady—state or off—cycle engine operation. The test data show that with the revised calibrations,

during FTP engine operation, the emission levels are below the applicable 1991 model—year emission

standards (0.10 g/bhp—hr PM and 5.0 g/bhp—hr NOx). Under forced, steady—state engine operation, the

PM emission levels are below 0.10 g/bhp—hr, and the NOx emission levels are below the 1990 model—

year emission standard of 6.0 g/bhp—hr.

        Based on the above, staff concludes that the exhaust emissions of the engines for which the

exemption is requested will not be adversely affected by the DDEC Engine Upgrade Kit and

recommends that DDC be granted an exemption for their upgrade kit as requested.
