(Page 1 of 3) State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—202—i 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 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.

State of California AIR RESOURCES BOARD EVALUATION OF DETROIT DIESEL CORPORATION®S DDEC ENGINE UPGRADE KIT FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13 OF THE CALIFORNIA CODE OF REGULATIONS 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.
