EVALUATION OF BAYTECH CORPORATION‘S NCV LINK 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 Baytech Corporation of P. 0. Box 1148, Los Altos, California 94023 has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code for the Baytech Corporation‘s NGV LINK. ‘The NGV LINK is designed for installation on 1992 and older model—year General Motors wehicles operating on compressed natural gas (CNG) and utilizing an Air Resources Board—certified conversion system. Baytech Corporation has submitted data from testing a 1992 GMC Sierra pick—up truck equipped with a 5.7 liter engine at U. S. EPA National Vehicle Fuel Emission Laboratory, Ann Arbor, Michigan. II. CoNCLUSTONS Based on test results conducted against the emission standards on a 1992 GMC Sierra pick—up truck, the staff concludes that Baytech Corporation‘s NGV LINK, will not adversely affect exhaust emissions from vehicles for which an exemption is requested. III. RECOMMENDATION The staff recommends that Baytech Corporation be granted an exemption for their NGV LINK, for 1992 and older model—year General Motors vehicles operating on CNG and utilizing an Air Resources Board certified conversion system. The staff also recommends that Executive Order D—272 be issued.

IV. DEVICE DESCRIPTION The Baytech Corporation‘s NGV LINK, is designed for installation on 1992 and older model—year General Motors vehicles operating on CNG and utilizing an Air Resources Board certified conversion system. The NGV LINK is a computer chip which optimizes the emissions, performance and fuel economy of General Motors vehicle converted to operate on CNG. The NGV LINK modifies various engine parameters to adjust for the use of CNG fuel. The NGV LINK also alleviates the trouble code problems associated with converting General Motors vehicles equipped with on—board diagnostic (OBD) systems to operate on CNG. This is accomplished by utilizing the original equipment manufacturer (OEM) algorithms abd adjusting the parameters to compensate for the CNG fuel composition. These modifications to the OEM electronic control unit are considered proprietary. The system 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 on gasoline also remain the same. v. EVALUATION AND DISCUSSION A 1992 GMC Sierra Pick—up truck equipped with a 5.7 liter engine was used for the evaluation of the NGV LINK. The dynamometer inertia weight and loading was 5500 lbs and 15.4 HP respectively. Emission tests conducted at U. S. EPA National Vehicle and Fuel Emissions Laboratory for Baytech Corporation consisted of one Cold—Start CVS~75

emission test in the modified (NGV LINK installed) configuration for the wehicle. The ARB did not perform tests to confirm the test results submitted by the applicant. A summary of the test results is shown below: Exhaust Emissions Test Results At U. S. EPA National Vehicle and Fuel Emissions Laboratory Test Exhaust Emissions (gm/mi) Mode NMEC co Nox GMC Sierra 0.01 2.0 0.1 GMC Sierra (w/DF) 0.01 2.1 0.1 Standard 0.5 9.0 1.0 Results from the emission test conducted at U. S. EPA National Vehicle and Fuel Emission Laboratory show the vehicle emissions with the Baytech Corporation‘s NGV LINK installed are within the emission standards. Therefore, based on the test results, the staff concludes that the installation of the Baytech Corporation‘s NGV LINK will not have an adverse effect on exhaust emissions of 1992 and older model—year General Motors vehicles operating on coméressed natural gas and utilizing an Air Resources Board certified conversion systems. Baytech Corporation submitted all the required information and fulfilled the requirements for exemption.
