                  Evaluation of Mallory Electric Company
                  "Mallory Unilite Model 502" Breakerless
                     Conversion Unit for Exemption from
                  the Provisions of Section 27156 of the
                               Vehicle Code


      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, "Mallory

      Unilite Mode? 502".    The applicant intends to market the device for

      installation on 1972 through 1976 model year Ford 8 cylinder

      vehicies equipped with a pivotal concentric breaker plate distributor.

      (Exhibit A).


      The applicant has been previously granted an exemption by Executive

      Order D—70, dated September 19, 1976 for the same device identified

      as "Mallory Unilite Mode] 501" for Delco 8 cylinder applications.

      The Model 501 is é]ectrically identically to the Model 502.


II.   System Description

      The device is a unit to replace the contact points within the

      distributor.    The opto/electronic module consists of a light

      emitting diode, an infrared detector, and a transistor switching

      circuit.   The module has been reduced in size through the use of

      thick film hybrid solid state circuitry.

Unilite Model 502" Breakerless Conversion Unit
for Exemption from the Provisions of Section
27156 of the Vehicle Code                                 October 8, 1976



     The module is mounted onto the distributor breaker plate using

     the screws supplied.    The shutter wheel has cut windows to allow

     lTight passage to activate the detector at the appropriate intervais.

     The wheel is mounted onto the distributor drive plate.     Exhibit B

     shows the electrical schematic of the device and Exhibit C is a

     copy of the installation instructions.


111. System Evaluation

     A.   Laboratory Tests

          The applicant did not submit any emission data indicating the

          device will not have any adverse effect on the emission

          control system.    In lieu of emission tests the applicant

          submitted an ignition bench test on a 1974 Ford 8 cylinder

          distributor by comparing the output characteristics of the

          ignition system with and without the device.     The test was

          accompliished 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 1973 Ford 8 cylinder distri—

          butor.   Table I and II are the summaries of the applicant‘s

          test data and the ARB Laboratory test results.


Evaluation of Mallory Electric Company "Mallory
Unilite Model 502" Breakerless Conversion Unit
for Exemption from the Provisions of Section
27156 of the Vehicle Code                                      October 8, 1976

    B.    Analysis of Test Results

         1.   Applicant‘s Test Data

              The back—to—back ignition systeim test data submitted

              by the applicant did not show any significant change

               in the centrifugal and vacuum advance of the distributor

              tested.   In addition, no degradation was noted of other

              critical ignition system parameters such as spark dura—

               tion, rise time, available secondary voltage, and energy.


              ARB Test Data

              The ARB confirmatory test showed that the device intro—

              duced a maximum of 6° engine ignition retard.      This 6°

               retard consisted of one degree delay in centrifugal

               advance and 5 degrees delay in vacuum advance.     A special

               test conducted with the governor of the distributor

               locked, however, showed no intrinsic advance or delay in

               the "Unilite" electronic module indicating fhat the

               centrifugal delay noted above could have been due to the

               test variability.     Likewise the vacuum advance data

               points have one degree test variability due to a + 0.5°

               accuracy in the distributor advance test bench readings.

               It is the staff‘s judgement that the 2° retard in excess

               of the ARB maximum 4° retard criteria can be attributed

               to the test variability.

Unilite Model 502" Breakertess Conversion Unit
for Exemption from the Provisions of Section
27156 of the Vehicle Code                                  October 8, 1976



                Table II also shows that the other critical ignition

                parameters were not adversely affected by the installa—

                tion of the "Vnilite" device.


          Manufacturers Clains

          The applicant claims the installation of the device on the

          motor vehicles will reduce tune ups, maintenance and adjust—

          ments .


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

          device on a vehicle could result in the following:

          1.    This breakerless system offers potential for reduced

                maintenance.
          2.        The electrical characteristics of this system do not

                indicate any significant benefits on the performance,

                fuel economy and emissions reduction greater than that

                would be expected from a properly tuned engine.


          Modification of the Intallation Instructions

          Item.No. 6 of the manufacturer‘s installation instructions

          recommends advancing the ignition timing so engine slightly

          pings under heavy load to obtain maximum engine performance

          and fuel economy.      Advancing the ignition timing over the

          manufacturer‘s specifications is not allowed per ARB ignition


Evaluation of Mallory Electric Company "Mallory
Unilite Model 502" Breakerless Conversion Unit
for Exemption from the Provisions of Section
27156 of the Vehicle Code                                  October 8, 1976



           system modifications criteria since this will increase the

           production of NOx.     The applicant was requested and agreed to

           delete the above recommendation from the installation instruc—

           tions.


IV.   Conclusion and Recommendation

      The above evaluation of the "Mallory Unilite Model 502" 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 Electric Company be

      granted an exemption from the prohibitions of Section 27156 of the

      California Vehicle Code for its "Mallory Unilite Model 502" LED

      breakerless ignition system for installation on 1972. through 1976

      model year Ford 8 cylinder vehicles equipped with a pivotal con—

      centric breaker plate 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 an application for an ARB resolution of compliance with

Section 27156 of the Califorria Vehicle Code for the Mallory Unilite

electronic conversion for the 72 and later concentric 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.

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

been previously submitted.

Description Of Device

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

corporates numerous design changes making it totally different than the

previous SS—1 conversion unit.

The new unit has been reduced in size through the use of thick flim hy—

brid solid state circuitry allowing the entire package to be mounted inside

the distributor offering simplified installation.

     Mr. G. C. Hass                       —2—                       $ September 1976


     Purpose of the Device

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

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

     the effects of point contact wear, timing changes,    & reduced energy out—

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

     tuneup maintainance & adjustments.

     Installation Instructions

     Detailed instruction sheets as well as two 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 Concentric Vacuum Plate Ford Distributor.     The tests were performed with

     strict adherence to the ARB guidelines for testing & evaluation of Ignition

     system modifications.   A copy is attached.

     The data on the Ford unit was taken using the D3AF12127AB Concentric vacuum

     advance plate.

     Application of the Device

     The Unilite #502 is manufactured for use with the 8 cylinder Ford dis—

     tributor from 1972 and later with conventional breaker point ignition.        If

     you have any questions regarding the enclosed information, please do not

     hesitate to call.

                                          Sincerely,       /

    Attn:     Fexrnand Tan


    Dear Mr. Tan:

         Regarding our recent teZlephone conversation concerning the letter
.   from Mr. Drachand, please modify the Mallony application to cover the
    1972 through 1976 model year Ford eight cylinder distributors equipped
    with a pivotal concentric breaker plate.

            The circuit diagram of the model 502 is identical to the 501 unit
    you have previousty evaluated. However, I have asked that one be formarded
    to you with the two sample devices.
            Please contact me if you have any further questions.
