State of California AIR RESOQURCES BOARD EXECUTIVE ORDER D—17 Relating to Exemptions under Section 27156 of the Vehicle Code CRAGAR INDUSTRIES, INC. "POWER PACK" Pursuant to the authority vested in the Air Resources Board by Section 27156 of the Yehicle Code; and Pursuant to the authority vested in the undersigned by Section 39023 of the Hea¥th and Safety Code; IT IS ORDERED AND RESOLVED: That the installation of "Power Pack" ignition system manufactured by Cragar Industries, Inc. 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 1966—1973 model—year vehicles. The device consists of a d—c to d—c converter, capacitor, and electronic switch {silicom controlled rectifier). This Executive Order is valid provided that installation instructions fqr this device will not recommend tuning the vehicle to specifications differemt than those 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 vehicle‘s pollution control devices shall invalidate this Executive Order. Marke@img of this device using an identification other than that shown in this Executive Order or marketing of this device for an application other than theose lHisted in this Executive Order shall have prior approval of the Air Resources Board.

EXECUTIVE ORDER D—17 . "POWER PACK" 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 "POWER PACK®" 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 writter communication. Section 17500 of the Business and Professions Code makes unlawfql, 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 pollution 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 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, advertise, or represent any motor vehicle pollution control device as an accredited device. Any violation of this section is a mis— demeanor." Any apparent violation of the policy or laws will be submitted to the Attorney General of California for such action as he deems advisable. Executed at Sacramento, California, this 41 day of August, 1973. JOHN A. MAGA Executive Officer

State of California AIR RESOURCES BOARD August 16, 1973 Staff Report Evaluation of Cragar Industries, Inc. "Power Pack" Capacitive Discharge Ignition Systems for Exemption to the Prohibitions of Section 27156 of the Motor Vehicle Code Introductfon Cragar Industries, Inc., Compton, California, has applied for exemption . to the prohibitions of Section 27156 of the Motor Vehicle Code for the "Power Pack" capacitive dischérge ignition system. Section 27156 profibits the installation of any device which reduces the effectiveness of motor vehicle emission control systems. The applicant intends to sell the device as an "add—on" part to the standard ignition system. 11. System Description For a general description of capacitive discharge ignition systems, see staff Feport "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 "Power Pack" device consists of circuits for a d—c to d—c converter, a storage capacitor and a silicon controlled rectifier which serves as an electrontc switch, and a trigger conditioner. The manufacturer

"Power Pack" August 16, 1973 states that the device produces up to 35,000 volts for secondary circuit output with a voltage rise time of 2 microsecond. III. Emission Testing The "Power Pack" device was tested by the Air Resources Board Labora— tory. The device was installed on a 1969 302 CID Ford. The vehicle engine and exhaust systems were checked to insure proper operation. For all tests, with and without the device, the engine settings were adjusted to the vehicle manufacturer‘s specifications. Baseline and device hot start CVS and 60 MPH cruise tests were per— formed. Fuel consumption was measured during the CVS test. Engine RPM and total spark advance were recorded during the 60 MPH cruise test. Open circuit spark voltages were noted at idle and at 3,000 RPM. The results of the ARB tests are shown below: Hot CVS Fuel Grams/Mile Consumption _HG CO NOx Grams/Test Baseline (Avg. of 3 tests} 4.07 23.21 5.5 1,331 Device 4.14 17.6 5.8 1,376

"Power Pack" August 16, 1973 — 60 MPH Cruise Engine Total Spark HC(ppm) CO(%) NOx(ppm) RPM Advance Baseline (Avg. of 3 tests) 197 0.37 2,666 2,400 32° BTDC Device 178 0.32 2,649 2,400 32° BTDC Open Circult Spark Voltage Idie (550 RPM) 3,000 RPM Baseline 26,000 . 16,006 Device 26,000 27,000 IV. Conclusions and Recommendations It is the staff‘s opiniofi'that the Cragar Industries, Inc., "Power Pack" capacitive discharge ignition system will not adversely effect 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 beneficial effect in the control of exhaust emissions if it maintains the "tuned" con— dition of the engine for a longer period of time. Therefore, the "Power Pack" capacitive discharge ignition system should be exempt from the prohibitions of Section 27156 of the Motor Vehicle Code.
