. ' State of California ‘ AIR RESOURCES BOARD September 8, 1976 Staff Report 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).

Hass, Chief Vehicle Emissions Control Program Air Resources Board 9528 Telstar Avenue El Monte, California 91731 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.

w__—__—__-_-_-----------------------.----.----..........ll.llllll.l.ll... ©® onace Mr. G. C. Hass —2— 12 July 1976 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.
