State of California AIR RESOURCES BOARD September 2, 1975 Staff Report 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.

Hass, Chief Division of Vehicle Emissions Control Air Resources Board 9528 Telstar Avenue El Monte, California 91731 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. ;%ncerely yours, ar / // /J/ y // Edward M. Junak // \ Chief Engineer ° EMJ/fs

Drachand, Chief Vehicle Compliance Air Resources Board Laboratory 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. ~L% l{y{?fifl/ /4 Edward Junak Vice Presi@gnt Engineering EJ/ei. Enc.
