                       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.

                            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.

    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

          The results of the ARB tests are shown below:

I¥.   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..
