EVALUATION OF AMERICAN GAS EQUIPMENT, INC.‘S NATURAL GAS ENGINE FUEL REGULATOR 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 American Gas Equipment, Inc. of 1111 Green Island Road, American Canyon, California 94589 has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code for the TESCOM high pressure natural gas engine fuel regulator, P/N 20—1032—2915. The TESCOM high pressure natural gas engine fuel regulator, P/N 20—1032—2915, is designed for installation on 1993 and older model—year passenger cars, light—duty trucks, medium—duty vehicles and heavy—duty engines oberating on compressed natural gas and utilizing an Impco conversion system. American Gas Equipment, Inc. has submitted a sample and specifications of the device for evaluation. II. CONCLUSTON Based on an engineering evaluation of the TESCOM high pressure natural gas engine fuel.regu1ator, P/N 20—1032—2915, the staff concludes that the TESCOM high pressure natural gas engine fuel regulator, P/N 20—1032—2915, will not adversely affect exhaust emissions from véhic]es for which an exemption is requested. III. RECOMMENDATION The staff recommends that American Gas Equipment, Inc. be granted an exemption for the TESCOM high pressure natural gas engine fuel regulator, P/N 20—1032—2915, for 1993 and older model—year passenger cars, light—duty trucks, medium—duty vehicles and heavy—duty engines operating on compressed natural gas and utilizing an Impco conversion system. The staff also recommends that Executive Order D—315 be issued.

IV. DEVICE DESCRIPTION The TESCOM high pressure natural gas engine fuel regulator, P/N 20—1032— 2915, is designed for installation on 1993 and older model—year passenger cars, light—duty trucks, medium—duty vehicles and heavy—duty engines operating on compressed natural gas (CNG) and utilizing an Impco conversion system. As with the Impco high pressure regulator, the function of the TESCOM high pressure natural gas engine fue? regulator is to reduce the CNG tank pressure to 100 psi. The 100 psi outlet pressure is required by the Impco brand second stage regulator. The functional difference between the two regulators is the TESCOM‘s ability to operate with a maximum tank pressure of 3600 psi compared to 3000 psi of the Impco system. . The regulator operates in conjunction with the OEM computer controlled electronic port fuel injection or carburetor, and emission control systems already certified with the stock engine. The tune—up specifications also remain the same. V. EVALUATION AND DISCUSSTON An engineering evaluation was conducted to evaluate the impact of the TESCOM high pressure natural gas engine fuel regulator on emissions. The TESCOM high pressure natural gas engine fuel regulator functions the same as the Impco regulator it replaces. It reduces the pressure from 3600 psi to 100 psi. American Gas Equipment claims the only difference between the two regulators fs the Tescom‘s ability to withstand an increased maximum tank pressure.

Therefore, since the device functions the same as the Impco‘s high bressure regd]ator, the staff concludes that the installation of the TESCOM high pressure natural gas engine fuel regulator, P/N 20—1032—2915, will not have an adverse effect on exhaust emissions of 1993 and older model—year passenger cars, lTight—duty trucks, medium—duty vehicles and heavy—duty engines operating on compressed natural gas and utilizing an Impco conversion system. American Gas Equipment, Inc. submitted all the required information and fulfilled the requirements for exemption.
