                        EXECUTIVE ORDER D—5
            Relating to Exemptions under Section 27156
                        of the Vehicle Code


                        DELTA PRODUCTS, INC.
               "MARK TEN, MARK TEN B AND MARK TEN C"


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 "Mark Ten, Mark
Ten B8 and Mark Ten C" capacitive discharge ignition system as a replace—
ment part manufactured by Delta 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 1966—1973 model—year vehicles.   The device consists of
a d—c to d—c converter, capacitor, and electronic switch (silicon con—
trolled rectifier).
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.

THIS. EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION,
APPROYAL, 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 "MARK TEN, MARK TEN B AND MARK TEN C" 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 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."

      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 uniess that device has been
      accredited by the board. No person shall sell, offer for sale, adver——
      tise, or represent any motor vehicle pollution control device as an

                              Staff Report

                     Evaluation of Delta Products, Inc.,
                        "Mark Ten, Mark Ten B and Mark
                     Ten C" Capacitive Discharge Ignition
               Systems for Exemption to the Prohibitions
               of Section 27156 of the Motor Vehicle Code




      Introduction

      Delta Products, Inc., Grand Junction, Colorado, has applied for

      exemption to the prohibitions of Section 27156 of the Motor

      Vehicle Code for the "Mark Ten, Mark Ten B and Mark Ten C"

      capacitive discharge ignition systems.     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 "after—market" part to replace the standard

      ignition system.


      The Air Resources Board has adopted criteria for the evaluation of

      "after—market" devices for compliance with Section 27156.     The basis

      for evaluation is defined in the "Air Resources Board Criteria for

      Determining Compliance with Section 27156 of the Vehicle Code®".


II.   System Description

      For a general description of capacitive discharge ignition systems,

      see staff report "Evaluation of Capacitive Discharge and Transistorized


"Mark Ten, Mark Ten B and Mark Ten C"                       March 16, 1973



        Ignition Systems for Compliance with the Requirements of Section

        27156 of the Motor Vehicle Code", dated February 14, 1973.


        Specificalfy, the "Mark Ten" devices consists of circuits for a

        d—c to d—c converter, storage capacitor and a silicon controlled

        rectifiér which serves as an electronic switch, and a trigger

        conditioner.     The devices produce a peak impulse of 1000 watts

        and a 400 volt rise in the primary coil in approximately 2 micro—

        seconds.     The "Mark Ten B" circuitry includes a feature to vary

        the spark duration from a stated 600 micro—seconds during starting

        and idle to 200 micro—seconds at high engine RPM‘s.

I11.    Emission Testing

       i The applicant has submitted hot CVS, hot 7—mode and 60 MPH steady—

        state test data conducted by Olson Laboratories (Table 1}.      The
        hot CVS test data is summarized below:

       The "Mark Ten B" device was tested by the Air Resources Board Lab—

       oratory.     The device was installed in a 1968 318 CID Plymouth and

       the engine put into a "tuned" condition.        See "Evaluation of Capacitive

       Discharge and Transistorized Igfiition Systems for Compliance with the

       Requirements of Section 27156 of the Motor Vehicle Code" for test

      \details.     The results of the "Mark Ten B" tests are listed below:

IV.    Conclusions and Recommendations

       It is the staff‘s opinion that Delta Products, Inc., "Mark Ten,
       Mark Ten B and Mark Ten C" capacitive discharge ignition system

      will not adversely effect motor vehicle exhafist 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


"Mark Ten, Mark Ten B and Mark Ten C"                March 16, 1973



      in that it maintains the "tuned" condition of the engine for a longer

      period of time.   Therefore, the "Mark Ten, Mark Ten B and Mark Ten C"

     capacitive discharge ignition systems should be exempt from the pro—

      hibitions of Section 27156 of the Motor Vehicle Code.
