               Relating to Exemptions under Section 27156
                           of the Vehicle Code


                         GAS MIZER INCORPORATED
                             "CAS MIZER"


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 the "Gas Mizer"
device manufactured by Gas Mizer Incorporated, 8399 Topanga Canyon Blvd.,
Canoga Park, California 91304 has been found to not reduce the effective—
ness of required motor vehicle pollution control devices and, therefore,
is exempt from the prohibitions of Section 27156 of the Vehicle Code for
1974 and older model—year vehicles except the following:     >

    1.   All vehicles equipped with a breakerless or electronic ignition
         system.

    2.   All 1966—70 model—year vehicles equipped with a Dana or Carter
         Nox retroift device using an electronic speed sensor.

The "Gas,Mizer" is a single wire coil wound in alternating directions
with a non—magnetic core. The coil is encapsulated in a plastic mold.
The device also includes two snap—fit electronic suppression cables.

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.

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 performance of the vehicle‘s po]]ut1on 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 those listed in this Executive Order shali be prohibited unless
prior approval is obtained from the Air Resources Board.

                                     Staff Report

                       Evaluation of the Gas Mizer Inc.,
                            "Gas—Mizer" Non—Magnetic
                          Coil for Exemption from the
                       Prohibitions of Section 27156 of the
                                  Vehicle Code


      Introduction

      Gas Mizer, Incorporated, 8399 Topanga Canyon Blvd., Canoga Park,

      California 91304 has applied for exemption from the prohibitions

      of Section‘ 27156 of the Vehicle Code for its "Gas Mizer" device.

      This section prohib{ts the installation of any device which may

      reduce the effectiveness of the motor vehicle emission control

      systems.     The applicant is requesting the exemption be granted for

      all 1974 and older model—year vehicles except the following:


          1.     All vehicles equipped with a breakerless or electronic

                 ignition system.

          2.‘ All 1966—70 model—year vehicles equipped with a Dana

                 or Carter NOx retrofit device using an electronic

                 speed switch.


II.   System Description and Function

      The device is installed between the OEM ignition coil and distri—

      butor.     It consists of a non—magnetic core (3/4 in. dia. wooden

      dowel 8—1/2 inches long) with electrical connection provided at


    each end.      The dowel is wrapped at the coil end with 11 turns of 300

    volt FR—1 Rome cable (300 gauge) followed by 47 turns of 23 gauge

    Nyleze wire.     The helix angle of the wrap is then reversed and 105

    more turns are made with the Nyleze wire.      Another helix angle

    reversal is made to wrap the last 57 turns at the distributor end.

    A photograph of the device is shown in Figure 1.


    The applicant claims that the device will improve fuel economy.


III. Device Evaluation

    A.   Applicant‘s Tests

         Gas Mizer submitted data that is intended to show the effects of

         the device on fuel economy.     A 1973 Pinto was driven 267.4 miles

         without the device and 288.4 miles with the device over sundnyn

         surface and freeway routes.     Data showing 7—10 percent increase

         in fuel economy was presented.     Because of the limited mileage

         accumuiation of a test and random driving routes and driving

         conditions used, the data is inconclusive.


         ARB Tests

         Two "Gas Mizer" devices were tested on a 1974 Dodge, 360 CID, EGR

         and automatic transmission to determine their electrical character—

         istics.     The following are the results of the tests:


              Centrifugal Spark Advance — Crankshaft Degrees

                                                                          Gas Mizer Device

                    Device Electrical Resistance — Ohms

                         Device No. 1   —    2.0

                         Device No. 2   —    2.0


      The electrical characteristics of the device are similar to the OEM

      system.   The device may slightly influence the required and available

      voltage at the spark plug by the addition of the device‘s resistance

      to the OEM system.


      The following are the results of idle emission tests performed

      on the 1974 Dodge:

                                        HC_— PPM          CO—%

          Baseline No. 1                    ©138           1.0
          Device No. 1                       117.5         0.78

          Baseline No. 2                      64           6.19

          Device No. 2                        64           0.50


      No apparent effects were produced by the devices in the idle emission
      tests.


IV.   Conclusions and Recommendations

      It is the opinion of the Staff that the "Gas Mizer" device does

      not reduce the effectiveness of required emission control systems.


Therefore, it is recommended that Gas Mizer Corporation be granted

an exemption from the prohibitions of Vehicle Code Section 27156 for

the "Gas Mizer" device for 1974 and older model—year vehicles

except for the following:


    1 — All vehicles equipped with a breakerless or electronic

        ignition system.

    2. All 1966—70 model—year vehicles equipped with a Dana or

        Carter NOx device using an electronic speed switch.
