State of California AIR RESOURCES BOARD March 11, 1975 Staff Report Evaluation of Mardek Corporation "Mobelec Electronic Ignition System" for Compliance with the Requirements of Section 27156 of the Motor Vehicle Code — Introduction Mardek Corporation, P.0. Box 2860, Newport Beach, California 92663 has submitted an application requesting an exemption from the prohibitions of Section 27156 of the Vehicle Code for the "Mobelec Electronic Ignition Sytem" (Reference — Exhibit A). . Vehicle Code Section 27156 prohibits'thé installation of any device or mechanism which adversely affects the pperation or performance of the emission control system. This sefition of the vehicle code also authorizes the Air Resources Board to exempt any device from this prohibition if a finding is made showing the device does not reduce the effectiveness of the emission control sysfem.‘ The applicant originally requested the exemptfon be granted on all 1974 and older model— year vehicfes originally equipped with convertional breakerpoint system. However, the app]fcant's letter of March 10, 1975 limited the vehicle app1ication to General Motors 8 cy]inder"and foreign vehicles originally equipped with a conventional breakerpoing ignition system and concentric pivot—point distributors. (Reference — Exhibit A) Tf. System Déscription The "Mobelec Electronic Ignition System" consists of the magnetic

pick—up unit, switching amplifier, a cam adapter for 4—cylinder application, a mounting plate for the magnetic pick—up unit and a special electric circuit for those Dana NOx device with an electronic speed sensor. The magnetic pick—up unit is mounted approximately the same location as breakerpoints (Reference — Exhibit B). Air gap between the cém Tobe and the pick—up unit is determined by a plastic ‘fee]er'gauge.‘ When the distributor shafts fotates, the high points of the cam lobe moving past the magnetic pi;k-up will generate an . electronic signal. Thifiysigna] actuates thé switch within the amplifier contro1Ting the current flow to the primary side of the cofl. The amplifier is basically a capacitive discharge system with typical electrical characteristics. (Reference — Exhibit C). The purpose of the "Mobelec Electronic Ignition System" is to reduce the maintenance associated with a breakerpoint system. It is claimed by the applicant that the installation of this device would simplify tune—up and provide better control of ignition timing. II1. System Evaluation . The applicant submitted Hot CVS—1972 emission data performed by Olson Laboratories, Inc. of 421 East Cerritos Avenue, Anaheim, California —92805. The test vehicles are described below: Make and Model—Year Engine (CID) Transmission Carburetor Emission Control System 1967 Buick Le Sabre > 340 , Automatic 4—Barrel AI—EM—Carter NOx devic 1967 Volkswagen 97 Manual v 1—Barrel STP NOx devi;e

The Volkswagen data indicate the device does not.haVe any adverse-effect_bn the emission control system. The ‘Air Resources Board Laboratory conducted tests to compare the advance characteristics:and the electrical outputs with and without the device on a vehicle. A comparison of the advance characteristics of —a Chrysler and Ford distributor using a distributor machine was performed. <In addition tests were performed to determine the compatibility of the "Mobelec" device with the Carter and Dana speed sensors. The vehicle used in the ARB tests is described below: * Make and Model—Year Engine (CID) Transmission Carburetor Emission Control — System 1974 American Motors 360 Automatic ?—Barrel AL—EM—EGR Ambassador Station Wagon

Installation of the "Mobelec Electronic Ignition System" indicated a significant change in spark timing on the Chrysler and Ford apb]ications above 10" Hg. vacuum. A spark retard of 8 degrees and 3 degrees was observed on the Chrysler and Ford distributors, respectively. An © additional 3 degree retard was observed on the Ford distributor when the engine speed is greater than 1500 rpm. This spark retard is caused by the off—center pivot movement of these distributors. Movement of this pivot cahses the spark to advance on breakerpoints system but . has no effect on the timing of breakerless systems. The étaff has established limits allowing no more than 4 degree of sustéined'retard above 55 mph. Therefore, the installation of this device on Chrysler and Ford vehicles is unacceptable. Excessive timing retard at high speed operation will reduce vaive lTife: This deterioration allows the valves to lose their sealing capacity which will increase hydrocarbon emission. The Dana speed sensor in addition, is not compatible with the "Mobelec" device therefore a special adopter— circuit is used for the Dana applications. No incomp#tibiTity exists between the Carter and "Mobelec" device. ‘The tests show the speeds which the speed sensor solenoid actuate are approximate]y identical With'and without the "Mobelec" device. IV. Conclusion and Recommendation The staff believes the installation of the "Mobelec Electronic Ignition System" will not lead to increases in exhaust emission on motor vehicle . applications. Therefore, the staff recommends that "Mardek‘Corporation be granted an exemption from the prohibitions of Section 27156 for 1974 and older model—year vehicles equipped with concentric pivot distributors {i.e. Gefiera] Motor 8 cylinder) and conventional breakerpoint ignition system.

Re:— Item II. Request for Board Finding. 1 Detailed Description: The Mobelec Electronic Ignition System features an electronic triggerhead sensing device. This unit is located within the distributor housing and next to, but not touching the O.E.M. distributor cam. As the distributor cam turns, the cam lobes revolve past the sensing triggerhead to break a magnetic field, that in turn is the signal required for discharging spark to the plugs as supplied by the Mobelec power module and O.E.M. coil. ' 2; Purpose of the device: _ * 2 The Mobelec Electronic Ignition is desiqgned to repléce conventional breaker points and condenser. This eliminates the need for reqgular replacement, simplifies tune—ups, and cuts maintenance costs. 3. Detailed Instructions for Installation: See attached. 4.

In selecting a mounting location for the unit, several things must be considered: the module must be close enough so the wires reach to the distributor and coil. . The electrical wires méy be shortened or lengthened ; however, the thick triggerhead lead wire MUST NOT BE CUT OR CRUSHED. — Tfy to find a cool place at least ©12" away from the exhaust system. Often the ideal location is somewhere near the front of the en'givne compartment, where cool air enters, After you have decided on the best place for the electrénic-module, mark the location for the three mounting holes. Drill three holes 1/8" diameter (3mm}. Place the ground wire under one of the mounting screws, making sure a good, clean connection is made. The spacers provided may beused to mount the unit on uneven surfaces. A good, clean ground connection is essential for correct operation. The ground \ wire may be extended if necessary. _ TRIGGERHEAD INSTALLATION 1. _ Remove distributor cap and rotor, 2. Remove ignition points and condenser. 3. See List A (back page) for approprfate adapter plate. 4. The adapter plates are designed to fit in place of the conventional breaker points. Position the adapter plate where the points had been. Notice that the threaded holes are used to mount the triggerhead while the remaining holes secure the adapter plate.

_—_P Exhibit B (Cont‘d) ~Page 13 of 16 February 17, 1975. To: Air Resources Board From: Mardek Corporation. The Carter Speed Sensor circuit operates according to manufacturers specifications with the !Hobelec ignition system by simply reconnecting the green lead from the Carter unit to the yellow lead terminal on the H.T. coil from the Mobelec. By connecting in this way, the Carter pulse sensing circuit is actuated by the ignition pulses from the Mobelec system and will operate at the same pulse speed setting. \The system performance was verified in accordance with the makers standard specifications. . Testing Method: Carter Device ‘ Rutomobile 1967 8 cylinder 340 CID Engine. h Using Carters specifications and collaborated by Mitchells Consumer Protection Handbook for retrofit smog devices, the following tests were conducted with the aid of an Autoscan 4000 apparatus. The Carter device was tested with conventional ignition. At 2510 RPM a change in vacuum was observed. This was found to be per manufacturers speclflcatlon. The test was repeated with conSLStancy six times. - The conventional iqgnition was removed and the Mobelec iqnition was installed. The green lead from the Carter device was changed from the regative side of the coil to the yellow lead of the Mobelec Iqgnition. This was done to actuate the Carter ignition pulse through and from the Mobelec Ignition. At 2510 RPM a change in vacuum was observed. The test was repeated six tlmes. Results were consistant. M =~ Tests were conducted at Olson Laboratories in Anaheinm.

P 6 Exhibit B (Cont‘d) Page 14 of 16 February 17, 1975. To: Air Resources Board} From: Mérdek Corporation. The Dana Retrofit NOx Speed Sensor device is normally connected to the positive terminal on the coil. The Dana device derives its power source from the nominal 8 ~ 12 volts positive on the coil terminal and incorporates an additional pulse sensing circuit which is actuated by the 8 ~ 12 volt pulses on the terminal of the coil, caused by the operation of the contact breakers and resistance drop across the ballast resistor. When the pulse rate is approximately equal to 1300 RPM onan 8 cylinder engine, the solencid valve circuit is switched. The Mobelec iqnition system.allows the Dana system to work according to the manufacturers specifications when the enclosed adaptor is w1red as per instructions. Laboratory tests measuring vacuum changes at manufacturers recommended RPM speeds indicated that the Dana Speed Sensor device functions correctly. No variations in the Dana Speed Sensor were found between conventional iqgnition with Dana retrofit, versus Mobelec ignition with adaptor and the Dana on a 1967 Buick 8 cylinder. Testing Method: Dana Device . . — Automobile 1967 8 cylinder 340 CID Engine. Using Dana‘s specifications and collaborated by specifications found in the Mitchell Consumer Protection handbook for retrofit smog devices, the following tests were conducted with the aid of an Autoscan 4000 apparatus. Conventional ignition equipped with the Dana NOx device was set to Dana‘s specification. —When the engine was brought to 1300 RPM vacuum change was observed on the vacuum gauge. The test was repeated six times. The conventional ignition was removed and the Mobelec ignition with adaptor and the Dana device was equxpped to the car and the test proceedure was repeated six times. The Dana devxce functloned exactly as it had with conventional lgn1tlon testing method. Tests were conducted at Olson Laboratories in Ansheinm.

Exhibit B (Cont‘d) Page 16 of 16 February 17, 1975. To: Air Resources Board From: Mardek Corporation. Mobelec Installation Instructions for Porsche/Audi vehicles originally equipped with a eapacitive discharge system When fitting a Mobelec breakerless iqnition system to an Audi or a Porsche . incorporating the Bosch electronic ignition system, i.e. BHKZ, the connector on the end of the Bosch iqgnition unit must be withdrawn, and taped to one side as it will not be required when the Mobelec system is installed., Aso the ‘leads connected to the terminals 1 and 15 on the H.T. coil are removed and taped securely to one side as they will not be required. . The I-iébelec system is then installed on the car in accordance with the standard fitting instructions.‘ ‘Care must be taken to insure that the red lead of the Mobelec is connected to a 12 volt ignition switch circuit which is operative during the cranking period. Also the idle solenoid valve fitted on the Audi carburetor must be left connected to the iqgnition switch, and on some models this means re— connecting this lead which was previously connected to the ignition coil terminal number 15, to an alternative supply, i.e. where the red lead of ‘the Mobelec system is connected.
