                                   SUMMARY




       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 (VC)   for the Baytech Corporation‘s NGV LINK.    The NGV

LINK is a computer chip designed for installation on 1992 and older model—year

General Motors vehicles operating on compressed natural gas and utilizing an

Air Resources Board certified conversion system.

       Based on the results from emisaion‘tests performed at the U. S. EPA

National Vehicle and Fuel Emission laboratory 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.

       The staff recommends that Baytech Corporation be granted an exemption as

requested and that Executive Order D—272 be issued.

                   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.
