State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—7 Relating to Exemptions under Section 27156 of the Vehicle Code AERO DESIGN PRODUCTS CORPORATION "PERMA—TUNE" 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 RESOLVED: That the installation of a "Perma—Tune" capacitive discharge ignition system as a replacement part manufactured by Aero Design Products Corporation has been found to not reduce the effectiveness of required emission control devices in vehicles and there— fore is exempt from the prohibitions of Section 27156 of the Vehicle Code for 1966—1973 model—year vehicles. The device consists of a d—c to d—c converter, storage capacitor and a thyristor electronic switch. This Executive Order is valid provided that installation instructions for this device will not recommend tuning the vehicle to specifications different than those listed by the vehicle manufacturer. THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION, APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF ANY CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF THE "PERMA—TUNE" DEVICE. No claim of any kind, such as "Approved by Air Resources Board" may be made with respect to the action taken herein in any advertising or other oral or written communication. Section 17500 of the Business and Professions Code makes unlawful, untrue or misleading advertising and Section 17534 makes violation punishable as a misdemeanor. Section 39130 and 39184 of the Health and Safety Code provide as follows: "39130. No person shall install, sell, offer for sale, or advertise, or, except in an application to the board for certification of a device, represent, any device as a motor vehicle poliution control device unless that device has been certified by the board. No person shall sell, offer for sale, advertise, or represent any motor vehicle pollution control device as a certified device which, in fact, is not a certified device. Any violation of this section is a misdemeanor."

EXECUTIVE ORDER D~7 "Perma—Tune" "39184. No person shall install, sell, offer for sale, or advertise, or, except in an application to the board for accreditation of a device, represent, any device as a motor vehicle pollution control device for use on any used motor vehicle unless that device has been accredited by the board. No person shall sell, offer for sale, adver— tise, or represent any motor vehicle pollution control device as an accredited device. Any violation of this section is a misdemeanor." Any apparent violation of the policy or laws will be submitted to the © Attorngy General of California for such action as he deems advisable. { 1 1 Executed at Sacramento, California, this 30 day of March, 1973. JOHN A. MAGA Executive Officer

State of California AIR RESOURCES BOARD March 16, 1973 Staff Report Evaluation of Aero Design Products Corporation "Perma—Tune" Capacitive Discharge Ignition System for Exemption to the Prohibitions of Section 27156 of the Motor Vehicle Code | I. fntroduction A?ro Design Products Corporation, Newport Beach, California, has afiplied for exemption to the prohibitions of Section 27156 of the Mqtor Vehicle Code for the "Perma—Tune" capacitive discharge iénition system. Section 27156 prohibits the installation of any device which reduces the effectiveness of motor vehicle emission control systems. The applicant intends to sell the device as an "after—market" part to replace the standard ignition system. The Air Resources Board has adopted criteria for the evaluation of "after—market" devices for compliance with Section 27156. The basis for evaluation is defined in the "Air Resources Board Criteria‘ for Determining Compliance with Section 27156 of the Motor Vehicle Code", dated February 14, 1973. II. System Description For a general description of capacitive discharge ignition systems, see staff report "Evaluation of Capacitive Discharge and Transistorized

"Perma—Tune" ’ March 16, 1973 Ignition Systems for Compliance with the Requirements of Section 27156 of the Motor Vehicle Code", dated February 14, 1973. The "Perma—Tune" device consists of a multivibrator d—c to d—c converter circuit, a storage capacitor and thyrister (silicon controlled rectifier) electronic switch circuit, and a trigger éonditioner circuit. The device is capable of producing a a secondary coil voltage rise of 50,000 volts per microsecond. \ Tbe arc discharge current is 0.8 to 1.0 ampere and a spark ~energy capacity of 60 millijoules. i III. Emission Testing Because of the number of applications received from manufacturers of capacitivé discharge ignition systems, it was decided to test one c—d device with ignition design characteristics that are considered to be representative of this group. A Delta Products, Inc., "Mark Ten B" system was selected for testing. The results of these tests are shown in the staff report "Evaluation of Capacitive Discharge and Transistorized Ignition Systems for Compliance with the Requirements of Section 27156 of the Motor Vehicle Code®". These tests verify that a capacitive discharge ignition system does not adversely effect the exhaust emfssions of a "tuned" engine. IV. Conclusions and Recommendations It is the staff‘s opinion that Aero Design Products Corporation "Perma— Tune" ignition system will not adversely effect motor vehicle exhaust

"Perma—Tune" March 16, 1973 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 beneficial effect in the control of exhaust emissions in that it maintains the "tuned" condition of the engine for a longer peribd of time. Therefore, the "Perma—Tune" cap— acitive discharge ignition system should be exempt from the prohibitions of Section 27156 of the Motor Vehicle Code.
