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 IV conversion kits. The reliabilt parts kit consists of remanufactured camshafts, blower assembly, turbocharger, and head assemblies. The converter/muffler kit consists of an Engine Control Systems direct-replacement oxidation catalyst and an exhaust temperature sensor. One of each type kit is required for the rebuild of an engine. For all of the applicable engines, DDC's revised certification word codes listed in Attachment A of the Executive Order must be used.

                              Relating to Exemptions Under Section 27156
                                           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 Detroit Diesel Corporation‘s (DDC‘s) 1985—1987
DDEC I, 1988—1990 DDEC II, and 1993 DDEC II 6VI2TA two—stroke urban bus diesel engines with
power ratings of 253 and 277 horsepower.

The DDEC Engine Upgrade Kit rebuilds all applicable 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 IV conversion kits. The reliabilt parts kit consists of remanufactured camshafts, blower
assembly, turbocharger, and head assemblies. The converter/muffler kit consists of an Engine
Control Systems direct—replacement oxidation catalyst and an exhaust temperature sensor. One of
each type kit is required for the rebuild of an engine.

For all of the applicable engines, DDC‘s revised certification word codes listed in Attachment A must
be used.


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


This exemption is based on emission tests conducted by DDC on a 6V9ZTA DDEC engine. DDC
conducted a series of hot—cycle emission tests using various horsepower, torque, test fuel, and engine
rotation combinations. The following are the highest hot—cycle federal transient heavy—duty diesel
engine test results for a 6VI2TA DDEC engine with a 277 horsepower rating:

                                          HC       CO .     NO       PM
                                        (grams per brake horsepower—hour)

               Hot—Cycle Emissions       0.10      0.23      4.59      0.09
               Emission Standard          1.3      15.5      5.0       0.10



The test data show that the 6VI2TA engine with the DDEC Engine Upgrade Kit meets the applicable
emission stardards. The same emissions impact is expected when the DDEC Engine Upgrade Kit is
installed on all 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 application other 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 reviewthis 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 eitherexpressed 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.
