                         EXECUTIVE ORDER D—20—2
               Relating to Exemptions under Section 27156
                           of the Vehicle Code


                         TRI—STAR CORPORATION
                             "TIGER SST"

Pursuant to the authority vested in the Air Resources Board by Section
27156 of the Vehicle Code; and

Pursuant to the authority vested in the undersigned by Section 39023 of
the Health and Safety Code;

IT IS ORDERED AND RESOLYED: That the installation of "Tiger SST" electronic
ignition system manufactured by Trir—Star Corporation has been found to
not reduce the effectiveness of required motor vehicle poliution control
devices and, therefore, is exempt from the prohibitions of Section 27156
of the Vehicle Code for 1974 and older model—year vehicles equipped with
12—volt negative ground batteries except the following:

     1.   1973—74 Mercedes Beni, Mazda, Audi and Porsche vehicles.

     2.   All General Motors vehicles equipped with an fgnition coil
          integrated into the distributor.

     3.   All 1966—70 model—year vehicles equipped with a Dana or Carter
          NOx retrofit device using an electronic speed sensor.

The "Tiger SST" is a solid—state electronic device which consists of a d—c
to d—c converter, capacitors, diodes, resistors, and silicon controlled
rectifier electronic switch.                  v

This Executive Order is valid provided that installation instructions
for this device will not recommend tuning the vehicle to specifications
different than thgse listed by the vehicle manufacturer.

Changes made to the design or operating conditions of the device as
originally submitted to the Air Resources Board for evaluation that
adversely affect the performance of the vehicle‘s pollution control
devices shall invalidate this Executive Order.

Marketing of this device using an identification other than that shown
in this Executive Order or marketing of this device for an application
other than those listed in this Executive Order shall be prohibited unless
prior approval is obtained from the Air Resources Board.

                Evaluation of the Tri—Star Corporation
                            "Tiger Pulsar"


The Tri—Star Corporation, Grand Junction, Colorado, has applied for exemp—

tion from the prohibitions of Section 27156 of the Ca]ifornia Vehicle Code

for the "Tiger Pulsar" electronic capacitive discharge ignition system.

Except for the labeling, the device is the same as the "Tiger 500" which

was previously exempted.   The applicant supplied enough information to

substantiate that "Tiger 500" and "Tiger Pulsar" are electronically

identical.


The attached staff report describes the "Tiger 500" device; it also shows

that the "Tiger 500" has no adverse effect on the existing emission control
system and recommends the "Tiger 500" for exemption from the prohibitions
of Section 27156 of the California Vehicle Code:


Since the "Tiger 500" and the "Tiger Pulsar" electronic capacitive dis—

charge ignition systems are in fact identical except for the labeling,

it is the ARB staff opinion that the "Tiger Pulsar" device should be
exempted from the prohibitiens of Section 27156 of the California Vehicle

Code.

                 Systems for Exemption to the Prohibitions
                 of Section 27156 of the Motor Vehicle Code


1.    Introduction

      The Tri—Star Corporation, Grand Junction, Colorado, has applied for

      exemption to the prohibitions of Section 27156 of the Motor Vehicle

      Code for the "Tiger 500" capacitive discharge ignition system.

      Section 27156 prohibjts the installation of any device which reduces

      the effectiveness of motor vehicle emission control systems.     The

      applicant intends to sell the aevice as an "add—on" part to the

      standard ignition system of 1974 and older model—year vehicles.


I1.   System Description

      For a general description of capacitive discharge ignition systems,

      see staff report "Evaluation of Capacitive Discharge and Transis—

      torized Ignition Systems for Compliance with the Requirements of
      Section 27156 of the Motor Vehicle Code", dated February 14, 1973.


      The "Tiger 500" device consists of circuits for a d—c to d—c

      converter, storage capacitor and a silicon controlled rectifier which

      serves as an electronic switch, and a trigger conditioner.

111. Emission Testing

    The applicant submitted an electrical schematic and described the

    system operation in addition to supplying CVS test data on three

    vehicles.   Based on the manufacturer‘s data and claims regarding no

    significant ignition system deterioration, there were no adverse ef—

    fects expected.     The emission data supplied was acquired at an altitude

    of 5,000 feet ana consequently confirmatory sea level tests were

    conducted by the ARB laboratory.


    The "Tiger 500" device was tested by the ARB laboratory on the following

    vehicles:


        1973 Chevrolet, 350 CID,;, 2 Bb1. Carb., EGR/AIR, Auto. Trans.

        1973 Mercury, 302 CID, 2 Bb1. Carb., EGR, Auto. Trans.

        1973 Plymouth, 360 CID, 2 Bbi. Carb., EGR/AIR, Auto. Trans.


    The idle air fuel mixture and ignition systems of both vehicles were

    prechecked to insure proper engine operation.    For all tests, with

    and without the device, the engine settings were adjusted to the

    vehicle manufacturer‘s specifications.


    The results of the ARB tests are shown below:

IV.   Conclusions and Recommendations
      It is the staff‘s opinion that the Tri—Star Corporation "Tiger 500"

      capacitive discharge ignition system will not adversely affect motor

      vehicle exhaust emissions when evaluated with respect to the exhaust

      emissions obtained with a conventional ignition system of a "tuned"

     engine.   This device may also have a beneficialveffect in the control

     of exhaust emissions if it maintains the "tuned" condition of the

     engine for a longer period of time.   Therefore, the "Tiger 500" capaci—

     tive discharge ignition system should be exempt from the prohibitions

    of Section 27156 of the Motor Vehicle Code for the mode] years shown

    in Executive Order D—20.
