State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—18 L Relating to Exemptions under Section 27156 of the Vehicle Code GENERAL PRODUCTS DIVISION/ GULF & WESTERN INDUSTRIES, INC. "YOLTRONIX" 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 RESOLYED: That the installation of "Voltronix" ignition system manufactured by General Products Division/Gulf & Western Industries, Inc. has been found to not reduce the effectiveness of required motor vehicle pollution 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 an amplifying transistor and a power transistor. 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. Chqnges 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. Marketing of this device using an identification other than that shown in this Executive Order or marketing of this device for an application other than these listed in this Executive Order shall have prior approval of the Air Resources Board.

EXECUTIVE ORDER D—18 | "VOLTRONIX" 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 "VOLTRONIX" 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." "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 poliution 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 2A day of August, 1973. JOHN A. MAGA Executive Officer

State of california AIR RESOURCES BOARD e August 16, 1973 Staff Report Evaluation of General Products Division/ Guif & Western Industries, Inc. "Yolitronix" Transistorized Ignition ; ; . Systems for Exemption to the Prohibitions of Section 27156 of the Motor Vehicle Code Introduction General Products Division, Sulf & Western Industries, Inc., Umon Springs, New York, has applied for exemption to the prohibftfons of Section 27156 of the Motor Vehiclie Code for the "Yoltronfx" transistorized—assisted contact ignition system. Sectian 27156 pro— hibits the installation of any device which reduces the effectiveness of motor vehicle emission control systems. The applicant frtends to sell the device as an "»add—on" part to the standard ignitton system. II. System Description For a general description of transistorized ignition systems, see staff repeft "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 "Yoltronix" device consists of circuits for an amplifying tran— sistor and a power transistor. The operation of the device relieves the contact points of making and breaking the full coflt current. 1.

"Yeltronix" ' August 16, 1973 The manufacturer claims that the device will maintain the proper dwell setting and timing for 50,000 miles. IHI. Em#fsston Testing The "Voltronix" device was tested by the Air Resources Board Laboratory. 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 adjfusted to the vehicle manufacturer‘s specifications. Easeltne 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 HC cCO NOx Grams/Test BaseTine {Aug. of 3 tests) 4.07 23.21 5.5 1,331 Revice 3.86 17.12 5.5 * * No fuel measurements made.

Concfusfons and Recommendations It fs the staff‘s opinion that the General Products Division/Guif & Western Industries, Inc., "Voltronix transistorized ignition system will not adversely effect motor vehicle exhaust emissions when eveluated with respect to the exhaust emissions obtained with a con— ventfonal ignition system of a "tuned" engine. This device may also have a beneficial effect in the control of exhaust emissions [ if it matntains the "tdned" condition of the engine for a longer period af time. Therefore, the "Voltronix" transistorized ignition system shauldrbe exempt from the prohibitions of Section 27156 of the Motor Y¥ehicle Code. -
