State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—8—1 Relating to Exemptions under Section 27156 of the Vehicle Code AIR QUALITY PRODUCTS, INC. "PURE POWER" 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 "Pure Power" capa— citive discharge ignition system manufactured by Air Quality Products, Inc. has been found to not reduce the effectiveness of required emission ‘control devices in vehicles and therefore is exempt from the prohibitions of Section 27156 of the Vehicle Code for 1955—1974 model—year vehicles except those vehicles originally equipped with electronic ignition sys tems and those 1966—70 model—year vehicles equipped with incompatible NOx devices (Reference Executive Order G—19—2). The device consists of a d—c to d—c converter, capacitor, and electronic switch (silicon controlled rectifier). This Executive Order is valid provided that installation instructions for this device will not recommend tuning the vehicle to specifications dif— ferent than those listed by the vehicle manufacturer. Changes made to the design or operating conditions of the device as original— 1y submitted to the Air Resources Board for evaluation that adversely affect 3h§ vehicle‘s poliution control devices shall invalidate this Executive rder. 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 "PURE POWER" 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.

Executive Order D—8—1 | "PURE POWER" 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 installi, sell, offer for sale, or advertise, or, except in an application to the board for certi— fication of a device, represent, any device as a motor vehicle polliution 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." "39184. No person shall install, sell, offer for sale, or advertise, or, except in an application to the board for accre— ditation of a device, represent, any device as a motor vehicle poliution 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, advertise, or represent any motor vehicle polliution 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 Attorney General of California for such action as he deems advisable. 1 ‘Executive Order D—8, dated March 19, 1973 is superseded and of no further force and effect. .

State of California AIR RESOURCES BOARD February 1, 1974 Staff Report Evaluation of the Air Quality Products, Inc., "PURE POWER" Capacitive Discharge Ignition Systems for Exemption to the Prohibitions of Section 27156 of the Motor Vehicle Code Introdgct1on Air Quality Products, Inc., Orange, California, has applied for exemption to the prohibitions of Section 27156 of the Motor Vehicle Code for the "Pure Power" capacitive discharge ignition system. Section 27156 prohibits the installation of any device which reduces the effectiveness of motor vehicle emission control systems. The applicant 1ntends_to sell the device as an "add—on" part to the standard {gnition system of 1974 and older model—year vehicles. II. 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 "Pure Power" device consists of circuits for a d—c to d—c converter, storage capacitor and a silicon controlled rectifier which

Air Quality Products, Inc. _ February 1, 1974 serves as an electrontic switch, and a trigger conditioner. III. Emission Testing The "Pure Power" capacitive discharge ignition system is identical in design and operation as the capacitor discharge system used in the accredited Air Quality Products‘ "55—65 Pure Power" and "66—70 Pure Power" emission control devices. No adverse effects attributed to the capacitive discharge ignition system section of the control devices were detected during their accreditation evaluations. Additional tests were performed on the "Pure Power" device by the Air Resources Board Laboratory. The following vehicles were used in the evaluation: 1973 Pontiac, 350 CID, 2 Bbl. Carb. EGR/AIR, Auto. Trans. 1973 Mercury, 302 CID, 2 Bb1. Carb. EGR, Auto. Trans. The ijdle air fuel mixture and ignition systems of both vehicles were prechecked to insure proper engine operation. For all tests, with and without device, the engine settings were adjusted to the vehicle manufacturer‘s specifications. Baseline and device hot start CVS tests were performed. The following are the results of the ARB tests:

Ar Quality Products, Inc. / February 1, 1974 Hot CVS Grams/M1le HC _CQ NOx_ 1973 Pontiac Baseline | 2.23 18.22 2.60 Device 2. 38 18. 33 2.38 1973 Mercury Baseline 2. 42 14.25 ~2.57 Device 2.52 16. 02 2. 50 1973 Mercury* Baseline 2. 48 13.93 2. 48 Device 2.51 14.60 2.57 *Tests repeated to establish cause of excessively large increase in CO emissions measured during the device test. Basic reason for the increase is attributed to a shift in the engine‘s operating condition. Baseline and device spark timing advance was measured on both vehicles. The data showed no significant difference between the curves produced by the device and the baseline vehicle. ' During baseline and device emission tests on the 1973 Pontiac, open circulit spark voltages were measured at idle and 2,200 engine RPM.

Air Quality Products, Inc. February 1, 1974 Open Circult Spark Voltage Idle(600 RPM) 2,200 RPM Baseline 22,000 voilits 22,000 volts Device 32,000 28,000 IV. Conclusions and Recommendations It is the staff‘s opinton that the Air Quality Products, Inc. "Pure Power" capacitive discharge ignition system will not adversely affect the performance of the motor vehicle exhaust emission control system 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 by maintaining the"tuned" condition of the engine for a longer period of time. Therefore, the "Pure Power" capacitive discharge ignition system should be exempt from the prohibitions of Section 27156 of the Motor Vehicle Code for the modei—year vehiclies shown in Executive Order D—8—1.
