(Page 1 of 3) State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—393—1 Relating to Exemptions Under Section 27156 of the Vehicle Code JOHNSON MATTHEY, INC. CAM CONVERTER TECHNOLOGY 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 Cam Converter Technology (CCT) Upgrade Kit, manufactured by Johnson Matthey, Inc. of 460 East Swedesford Road, Wayne, Pennsylvania 19087—1880, has been found not to reduce the effectiveness of the applicable vehicle pollution control system, and therefore, the CCT Upgrade Kit is exempt from the prohibitions of \ |mt Section 27156 of the Vehicle Code for installation on 1985—1993 model—year Detroit Diesel Corporation (DDC) 6V92TA DDEC two—stroke urban bus diesel engines with power ratings of 253 2 and 277 horsepower. The CCT Upgrade Kit rebuilds all applicable engines to federal 1991—1993 model—year DDC specification. The CCT Upgrade Kit is exempt only when used in conjunction with other DDC engine rebuild parts. The required CCT Upgrade Kit parts and DDC rebuild parts are listed in the parts lists which are attached hereto and incorporated herein. The CCT Upgrade Kit includes patented engine camshafts, CCT cylinder kits, CEM II catalytic muffler, and 0.015 offset key to retard fuel injection timing. For 1985—1987 model—year engines, the CCT Upgrade Kit also includes DDEC I to DDEC II conversions parts, fuel injectors, turbocharger, blower assembly, blower bypass valve, 40—tooth blower drive gear, and an ECM upgrade. For 1988—1990 model—year engines, the CCT Upgrade Kit also includes fuel injectors and an ECM upgrade. This Executive Order may be modified to reflect any changes resulting from the NOx map issue currently being reviewed by U.S. EPA due to the ECM upgrade for 1985—1990 model—year engines. The future resolution will be appropriately incorporated in the exemption. This exemption is based on emission tests conducted by Johnson Matthey, Inc. on a 1992 model—year 6V92TA DDEC II engine rebuilt to a federal 1991 model—year urban bus engine configuration. Johnson Matthey, Inc. submitted the following federal transient heavy—duty diesel engine test results Lentwusesim, for a 552 cubic inch 6V92Z2TA DDEC engine with a 277 horsepower rating:

JOHNSON MATTHEY, INC. EXECUTIVE ORDER D—393—1 CCT UPGRADE KIT (Page 2 of 3) ¥ a@& HC CO NOx PM {grams per brake horsepower—hour) Baseline 0.46 1.18 4.88 0.188 With CCT Kit 0.2 0.6 4.98 0.091 Emission Standard 1.3 15.5 5.0 0. 1 The test data show that the CCT Upgrade Kit did not adversely affect the exhaust emissions of the DDEC 6V92TA engine. The same emissions impact is expected when the CCT Upgrade Kit is installed on the engines for which the exemption is requested. This Executive Order is valid provided that installation instructions for the CCT 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 CCT 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 CCT 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 review this Executive Order and the exemption provided herein to assure that the exempted add—on or modified part continues to meet the standards and procedures of Title 13, California Code of Regulations, Section 2222 et seq.
