              Evaluation of Tri—Star Corporation
         "SST—W Capacitive Discharge Ignition" System
            For Exemption from the Prohibitions of
            Section 27156 of the Motor Vehicle Code


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

tion from the prohihitions of Section 27156 of the Motor Vehicle Code

for the "SST—W Capacitive Discharge Ignition" system to be marketed by

Warshawsky & Co., Inc. and J.C. Whitney Co.    Section 27156 prohibits the

installation of any device which reduces the effectiveness of motor vehicle

poltution control systems.    The applicant intends to sell the device as

an "after—market" part to augment the existing standard ignition system

for 1974 and older model year vehicles equipped with a 12—volt negative

ground battery, except the following:

A.   1973—74 Mercedes Benz, Mazda, Audi and Porsche vehicles.

B.   All Genreral Motors vehicles equipped with an ignition coil

     integrated into the distributor.

C.   All 1966—70 model—year vehicles equipped with a Dana, Carter,

     or AQP NOx retrofit device using an electronic speed sensor.


The Air Resources Board has adopted criteria for the evaluation of

"aftor—market" devices for compliance with Section 27156.       The basis

for evaluation is defined in the "Air Resources Soard Criteria for

Dotermining Compliance with Section 27156 of the Motor Vehicle Code",

dated February 17, 1971.


[1.   System Description

      The "SST—W Capacitive Discharge Ignition" is a solid—state printed—

      circuit ignition system which consists of a d—c to d—c converter, a

      rectifier bridge, a storage capacitor, a coil, resistors, diodes, and

      a silicon control rectifier.   The module is attached to the frame of the

      vehicle and used in combination with the standard Kettering ignition system

      component or with breakerless ignition systems.


      An earlier model of the Tiger series manufactured by Tri—Star, the "Tiger

      SST‘", was previously tested by the ARB staff; see staff report entitied

      "Evaluation of the Tri—Star Corporation "Tiger SST", dated June 12, 1974.

      The "SST—W" device is technically the same as the previously evaluated

      "Tiger SST" device.   The "SST—W" model, however, is not equipped with

      a function switch allowing restoration of the standard ignition.   Aside

      from the function switch there is no significant circuit difference between

      the "Tiger SST" and the "SST—W" devices as shown in the following comparison

      of schematics in Figure I.

III. Staff Evaluation

      The ARB staff report entitled "Evaluation of the Tri—Star Corporation

      "Tiger SST", dated June 12, 1974 shows that the installation of the

      "Tiger SST" electronic capacitive discharge ignition system will not

      adversely affect the existing emission control devices in a motor vehicle.

      Since the "SST—W" and the "Tiger SST" devices are identical except for the

      function switch deleted from the "SST—W" model, the ARB staff believes that

      the "SST—W" should have no adverse effects on exhaust emissions.


IV.   Conclusions and Recommendations

      It is the staff opinion that Tri—Star Corp. "SST—W" Capacitive

      Discharge Iqgnition" system will not adversely affect motor vehicle

      exhaust emissions.   Therefore, the "SST—W" Capacitive Discharge

      Ignitions" system should be exempt from the prohibitions of Section

      27156 of the Motor Vehicle Code for 1974 and older model—year vehicles

      equipped with a 12—volt negative ground battery except the following:

      A.   1973—74 Mercedes Benz, Mazda, Audi, and Porsche.

      B.   «All vehicles equipped with an ignition coil integrated into the

           distributor of with an electronic ignition system whether it is

           a breakerless, capacitive discharge, or transistorized type.

      C.   All 1966—70 model—year vehicles equipped withva Dana, Carter,

           or AQP NOx retrofit device using an electronic speed sensor.


                                                                   "Exhibit A"

             Dear Mr. Hass:

                         This is a request to extend coverage of our exemption
             granted by Executive Order D—20—2 to include units built by us but
             marketed by Warshawsky & Company.

                       The units marketed by Warshawsky are identical in all
             details to our TIGER SST except that:

                       1.     The name TIGER SST is not displayed on those pnits.

                       2.     The electrical switch, which allows selection
                              of either STANDARD ignition or C.D. ignition,
                              is deleted along with associated nomenclature.

                       The units as built have only connection sequence
             printed on them identical to our SST.     Additional identification
             can be added if necessary.

                       Thank you for your early consideration of this
             matter.

            Vehicle Compliance

            9528 Telstar Avenue
            El Monte, California 91731


            Dear Mr. Drachand:

            In reference to previous correspondence and telecom with Mr. Luczymski
            on August 4, 1975, we are enclosing requested data concerning the ex~
            emption of our SST units sold by Warshawsky and Whitney.

            1.       Units will be identified with nomenclature "SST—W Capacitive Discharge
            Ignition".  Nomenclature will be printed on the unit end plate.  No model.
            or part number is used since only the one model is marketed with this des—
            ignation.

            2.   With regard to "design changes" there are nome from our SST. Dele—
            tion of the switch which allows selection of original configuration
            ignition is not considered a design change but an option change.
            Deletion of the switch has no effect on performance of the capacitive
            discharge ignition unit. Note that identical components are used and
            connected in the SST—W as used and commected in our SST except:

                          1.   The switch is deleted along with its mounting rivets.
                          2.   Wires routed through switch in the SST are connected
                             directly to circuit board on the SST—W part.
                          3.  The end plate on the SST—W has 3 less holes punched
                            due to deletion of switch and switch rivets.
                          4. Nomenclautre printed on unit is different.

            Enclosed is schematic of the SST—W unit along with schematic of the SST
            unit in current production.

            Your early consideration in extending the D—20—2 exemption is appreciated.
            Please call collect if any additional information is required.
