State of California AIR RESOURCES BOARD EXECUTIVE ORDER D—19 Relating to Exemptions under Section 27156 of the Vehicle Code C. A. JACOBS "C. A. JACOBS" 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 "C. A. Jacobs" ignition system manufactured by C. A. Jacobs 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 a d—c to d—c converter, capacitor, and electronic switch (siticon con— trolled rectifier). This Executive Order is valid providea that installation instructions for this device will not recommend tuning the vehicle to specifications different 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. j 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 those listed in this Executive Order shall have prior approval of the Air Resources Board.

EXECUTIVE ORDER D—19 "C.A. JACOBS® 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 "C.A. JACOBS" DEVICE. No claim of any kind, such as "Approved by Air Resources Bgard“ 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 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.

Q > State of california AIR RESOURCES BOARD ~August 16, 1973 Staff Report Evaluation of the C. A. Jacobs | "C. A. Jacobs" Capacitive Discharge Ignition Systems for Exemption to the Prohibitions of Section 27156 of the Motor Vehicle Code I. Introduction C. A. Jacobs, Los Angeles, California, has applied for exemption to the prohibitions of Section 27156 of the Motor Vehicle Code for the "C. A. Jacobs" capacitive discharge ignition 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 " add—on" part to the standard ignition system. 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 "C. A. Jacobs" device consists of circuits for a d—c to d—c converter, storage capacitor and a silicon controlled rectifier which serves F :‘ _ as an electronic switch, and a trigger conditioner.

& w "C. K. Jacobs" August 16, 1973 III.. : Enission Testing The "C. A. Jacobs" 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 «ltests, 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— fiormed. Fuel consumption was measured during the CVS test. Engine RAMand total spark advance were recorded during the 60 MPH cruise M test. Open circuit spark voltages were noted at idle and at 3,000 | REML.. The results of the ARB tests are shown below: Hot CVS Fuel Grams/Mile Consumption HC Co NOx Grams/Test Baseline ((Avg. of 3 tests) .4.07 23.21 5.5 1,331 Gevice 4.12 21.49 5.7 1,303 60 _MPH Cruise _ Engine Total Spark HC(ppm] CO(%) NOx(ppm) RPM Advance Baseline E (Avg. of 3 tests) 197 .37 2,666 2,400 32° BTDC Devtce 183 ©‘0.38 2,699 2,400 32° BTDC

Conmefustons and Recommendations It fis the staff‘s opinion that the C. A. Jacobs, "C. A. Jacobs" cepacttive discharge ignition system will not adversely effec;t matormr vehicle exhaust emissions when evaluated with respect to the exthaust emissions obtained with a conventional ignition system of a "tuned" engine. This device may also have a beneficial effect im the control of exhaust emissions if it maintains the "tured" condition of the engine for a longer period of time. There— fare, the "C. A. Jacobs" capacitive discharge ignition system should be exempt from the prohibitions of Section 27156 of the Motor Vehicle Cade..
