                      Evaluation of Mallory Electric Company
               "Mallory Unilite Model 501" Breakerless Conversion Unit
                        for Exemption from the Provisions of
                          Section 27156 of the Vehicle Code


    I.      Introduction

           Mallory Electric Company, Division of W. R. Grace & Co., 1801 Oregon

           Street, Carson City, Nevada, 89701, has applied for an exemption for

           its breakerless ignition conversion device.     The applicant had

           originally applied for an exemption for 1957 through 1974 model year

           vehiclies equipped with a Delco or Ford 8 cylinder distributor ~{Exhaust A).

.          The application was later revised (Exhibit B) to inlcude only Delco 8

           cylinder distributors.     This device will be marketed as. "Mallory

           Unilite Model 501."


    II.    System Description

           The device is.a unit to rep1ébe the contact points within the dis—

          \tributor.   It consists primarily of an opto/electronic module and

           a Shutter wheel.     The electronic module—consists of a lTight emitting

           diode, an infrared detector, and a transistor_switching-6ircuit.        The

           module has been reduced in size through the use of thick film hybrid

           solid state circuitry.     The module is mounted onto the distributor

           breaker plate using the screws supplied.     The shutter wheelhas cut

           windows to allow light passage to activate the defector at the

           appropriate intervals.     The wheel is mounted onto the distributor

           rotor drive plate.     Exhibit C shows the electrical schematic of the

           device.


                ..



      .   III. System Evaluation

                The applicant did not submit any emission data indicating the dévice

                will not have any adverse effect on the emission control system.      In

                lieu of emission tests the applicant submitted an ignition system

                bench test og a 1968 Delco 8 cylinder distributor by comparing the

                output characteristics of the ignition system with and without the

                device.   The test was accomplished on an ignition system simulator

                in accordance with "ARB Guidelines for Testing and Criteria for

                Emission Compliance of Ignition System Modifications".     The ARB per—

                formed a confirmatory test on a 1974 Delco 8 cylinder distributor.         Table

                I and 11 are the summaries of applicant‘s test data and ARB Laboratory

                test results.


                The applicant‘s test data showed about a 20% reduction in available

      .         secondary voltage with the device instalied at the condition simulating

                fouled spark plug.   However the ARB Laboratory confirmatory test on the

                1974 Delco distributor did not show any significant degradation of the

                secondary voltage from OEM.


                Both the applicants test data and ARB Laboratory test results indicated

                no significant degradation of other critical ignition system parameters

                such as spark advance, spark energy, and spark dfiration.


          IV.   Manufacturer‘s Claims

                The applicant claims the installation of the device on the motor

                vehicles will reduce tune ups, maintenance and adjustments.
in
ina
ul


It is the staff‘s judgement that the installation of the devicé on

a vehicle could result in the following:

1.   This breakerless system offers potential for reduced maintenance.

2.   The electrical characteristics of this systém do not indicate

     any significant bemefits on performance, fuel economy and emissions

     reduction greater than would be expected from a properly tuned

     engine.


Conclusion and Recommendation

The above evaluation of the "Mallory Unilite Model 501" unit by the

ARB staff showed that the installation of the device will not adversely

affect the ignition characteristics of the OEM ignition system.


The staff therefore recommends that Mallory Electéic Company be granted

an exemption from the prohibitions of Section. 27156 of the California

Vehicle Code for its "Mallory Unilite Model 501" for installation on

1957 through 1974 model year vehicles equipped with a Delco 8 —cylinder

distributor except as follows:

1.   Those vehicles originally equipped with breakerless ignition

     systems .

2.   Those 1966 through 1970 vehicles equipped with "NOx retrofit

     devices" with a 4° retard in basic ignition timing (i.e.,

     Carter, Echlin, STP Air Computer, Pure Power — Electro—NOx).

    Subject:    Application for an ARB Resolution of Compliance with Section
                27156 of the California Vehicle Code.

    Dear Mr. Hass:

    This letter is afi application for an ARB resolution of compliance with

    Section 27156 of the California Vehicle Code for the Mallory Unilite

    electronic conversion for the Delco & Ford Distributors.

    I am applying for the exemption in behalf of the Mallory Electric Company,

    a wholly owned subsiderary of the W. R. Grace Company of New York.         It

    is the function of our test center in Garden Grove to offer our test labs

    & services to the Automotive Specialties Divisions of W. R. Grace as well

    as represent them with all state & federal agencies.

    A copy of a letter authorizing me to act in behalf of Mallory Electric is

    attached.

    Description of Device

    The device is a unique breakerless conversion ignition device that in—

    corporates numerous design changes making it totally different than thé

    previous SS—1 conversion unit.

         The new urit has been reduced in size through the use of thick flim

         hybrid solid state circuitry allowing the entire package to be mounted

         inside the distributor offering simplified installation.

         Purpose of the Device

         The purpose of the device is to replace the conventional Ereaker points

         with a non—contacfing infrared triggered unit.      The conversion eleminates

         the effects of point contact wear, timing z‘:hanges, & reduced energy out—

         put of the conventional point contact system.      It thereby offers reduced

         tfineup maintainance & adjustments.

.        Installation Instructions

         DBetailed instruction sheets as well as 2 sample units will be immediately

         forwarded under separate cover for your evaluation.

         Test Data.

         Bench test data has been supplied as per The ARB quidelines of 3—1—76

         for the Delco & the Ford Distributor.      The tests were performed wa.th strict

         adherence to the ARB guidelines for testing & evaluation of Iqnition sys—

         tem modifications.    A copy is attached                         ‘

         The Data on the Ford unit was takefi using the earlier 1969 eccéntric

         vacuum advance plate.

         Data is being compiled for the latter pivotal concentric unit & will be

         forwarded when completed.

.        Application of the Device

—        The Unilite #501 is manufactured to work with the 8 cylifider delco dis—

         tributors from 1957 to 1974 with the conventional breaker point ignition.
