State of California AIR RESQURCES BOARD October 8, 1976 Staff Report 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.

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 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.

Evaluation of Mallory Electric Company "Mallory 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).

Hass, Chief Vehicle Emissions Control Program Air Resources Board 9528 Telstar Avenue E1 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 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.

©@ crace 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, / © 7A {f2a—————— Andy Krumm Director of Research & Development
