            Evaluation of M. W. Raybin "Raybin Magnetic
             Discharge" Transistorized Ignition System
            for Exemption to the Prohibitions of Section
                   27156 of the Motor Vehicle Code




       Introduction

      M. W. Raybin, Lawndale, California, has applied for exemption to

       the prohibitions of Section 27156 of the Motor Vehicle Code for

       the "Raybin Magnetic Discharge" transistorized ignition system.

      Section 27156 prohibits the installation of any device which reduces

       the effectiveness of motor vehicle emission control systems.   The

      ‘applicant intends to sell the device as an "after—market" part to

       replace the standard ignition system.


      The Air Resources Board has adopted criteria for the evaluation of

       "after—market" devices for compliance with Section 27156.   The basis

       for evaluation is defined in the "Air Resources Board Criteria for

       Determining Compliance with Section 27156 of the Motor Vehicle Code".


II.    System Description

       For a general description of transistorized ignition systems, see
      staff report "Evaluation of Capacitive Discharge and Transistorized

       Ignition Systems for Compliance with the Requirements of Section

      27156 of the Motor Vehicle Code", dated February 14, 1973.


"Raybin Magnetic Discharge"                     >      March 16, 1973



       The "Raybin Magnetic Discharge" device consists of a transistor,

       ballast resistor and an auto—transformer to impact an electrical

       pulse (200 volts) across the primary of the ignition coil.    The

       system has a spark energy capability of 60 millijoules.


111.   Emission Testing

       %ecause of the number of applications received from manufacturers

       of transistorized ignition systems, it was decided to test one

       éransistorized device with ignition design characteristics repre—

       séntative of this group.    A Solid State Products, Inc. "SSP Stagé

       I%" system was selected for testing.    The results of these tests

       age shown in the staff report "Evaluation of Capacitive Discharge

       and Transistorized Ignition Systems for Compliance with the

       Requirements of Section 27156 of the Motor Vehicle Code".     These

       tests verify that a transistorized ignition‘system does not adversely

       effect the exhaust emissions of a "tuned" engine.


IV.    Conclusions and Recommendations‘

       It is the staff‘s opinion that the M. W. Raybin “Raybin Magnetic

       Discharge" transistorized ignition system will not adversely effect

       motor vehicle exhaust emissions when evaluated with respect to the

       exhaust emissions obtained with a conventfiona] ignition system of a

       "tuned" engine.    This device may also have a beneficial effect in the

       control of exhaust emissions in that it maintains the "tuned" con—

       dition of the engine for a longer period of time.   Therefore, "Raybin


"Raybin Magnetic Discharge"                          March 16, 1973



     Magnetic Discharge" transistorized ignition system should be

     exempt from the prohibitions of Section 27156 of the Motor

      Vehicle Code.

            Evaluation of Capacitive Discharge and
             Transistorized Ignition Systems for
             Compliance with the Requirements of
           Section 27156 of the Motor Vehicle Code




 Introduction

 Section 27156 of the California Motor Vehicle Code prohibits the

 installation of a device, apparatus or mechanism which, when used

 with a required motor vehicle emission control system, alters or

 modifies the emission control system in such a manner that it

 reduces the effectiveness of the emission control system.


 In order to determine whether a device constitutes a violation of

~ Section 27156, the device manufacturer shall submit an application

 requesting that the Air Resources Board make an evaluation of the

 device‘s effect on emissions.    By established policy, the evaluation

 is limited to the emission effects and does not include evaluations

 of vehicle driveability and performance and device durability.


 Several applications have been received from manufacturers of

 capacitive discharge and transistorized ignition systems requesting

an evaluation of their devices.

II.    System Description

      A.   Standard Inductive System

           The conventional ignition system is of the magnetic inductance

           type.        The basic components of the system are a battery,

           ignition coil, breaker points, condenser, rotor and spark plugs.

           The schematic of a typical system is shown below:

                    ~           Resistor

                   | Capacitor _lfi           [Points
             ,;”




           The system has two circuits, primary and secondary.                        When con—

           tinuity is established by closing of the switch and breaker

           points, current will flow in the primary circuit building up a

           magnetic field around the coil.                    When the breaker points are

           opened, the maéneti; field slowly collapses and induces a current

           flowing in the same direction in the primary circuit.                       The
           current charges a capacitor until the capacitor builds a poten—

           tial opposing flow and discharges                   back through the primary

           circuit.       This causes a sudden collapse of the remaining magnetic

           field and induces a high voltage in the secondary coil winding.

           The secondary coil voltage is also cut by the collapsing magnetic

           field.

Section 27156 of the Moter Vehicle Code           —       February 14, 1973




          The secondary circuit consists of the high tension coil, wires,

          and a mechanical device for the proper timing of the voltage

          to the spark plugs.


          The external resistor in the primary circuit is to reduce the

          current at low speeds—while not—appreciably restricting the

          current flow at high speeds.      The resistor is bypassed during

          starting of the engine.


          Transistorized Inductive Ignition Systems with Breaker Points

          A typical transistorized system maintains the same basic com—

          ponents as the standard system except the condenser is replaced

          with a transistor and the coil is replaced by a coil of a

          special design.      A typical transistorized system is shown below:

         The transistor acts as a switch in the primary circuit, replacing

         the breaker points ofkthe standard system in this function.          The

         breaker points now serve as a switch for the triggering current

         to the transistor. With the points closed, the current flow from

         the emitter to ground (triggering) circuit through the points

          is considerably reduced, thereby improving the life of the

          points.    Opening of the points stops the flow of triggering

         current and cuts off the transistor current.


         The transistor also acts as a current amplifier.     The primary

         current flowing through the emitter—collector circuit in series

         with the low—tension coil and battery is greatly amplified

         over the triggering current.     The inductance of the coil and

         the ballast resistor limit the current flow through the coil.


         Zener diodes are used to protect the transistor by clipping or

         eliminating the primary voltage pulse below the minimum voltage

         rating for the emitter to collector.

         The coil used in the transistorized system has a higher ratio

&        of turns in the secondary/primary coils.    The increased number

         of turns in the secondary coil reduces the reverse voltage in

         the primary cfrcuit without reducing the high voltage output of

         the coil.    The high revérse voltage and current of the conven—

         tional system sometimes cause arcin§ across the breaker points

         of the conventional system.


         The advantages of the transistorized igniticn system are:

         1.   Increased point life due to reduction in current flow

                   through thé breaker points.     Other distributor maintenance

                    is required.

          2.        Increased output voltage available for higher engine speeds.

          3.        Increase in spark energy.


         Breakerless Transistorized Induction IgnitionSystems

          in the breakerless ignition system, the transistor base current

          is controlled by a triggering circuit and a breakerless pick—up

         used in place of the distributor points.           The trigger unit is

         activated by a magnetic pulse generator or photocell mounted ifi

         the distributor.           A typical circuit is shown below.       The

         remaining circuit is as previously described.

     D.     Capacitor Discharge Ignition Systems with Breaker Points

            A capacitor discharge‘system consists of three basic circuits.

            A power circuit which converts battery voltage to a higher

            voltage.    A tank capacitor which stores and discharges the high

            voltage current supplied by the power circuit.                 A switching

            circuit which accepts signals from the engine and discharges

            the ténk capacitor into the primary windings of the transformer.

           The advantages of a, capacitor discharge ignition system are:

           1.   Increase disfributor point Tife due to reduction in éurrent

                flow through the breaker points.       Other distributor

                maintenance remains the same.

           2.   Increase spark plug life due to faster output voltage

                rise time.

           3.   Increased output voltage at higher engins speeds.

           4.   Improved engine startability at low temperatures .

       E.   Breakeriess Capacitor Discharge Ignition System

            The breakerless C—D system contains the same basic elements

            as the contact—triggered system except the triggering circuit

            is controlled by a breakerless pick—up in place of the distrib-‘

            utor points.    As in the breakerless transistor system, the
            pick—up may be a magnetic pulse or optical trigger source.       in

            addit{on to the advantages previously described for C—D systems,

            breakerless systems have the following advantages:

            1.   Eliminates periodic maintenance of the distributor.


111.   Emission Testing

       To determine the effect of transistorized and capacitor discharge

       ignition systems on exhaust’emissjons, hot CVS tests were performed

       on devices considered to be typical of each type.     The systems

       selected were Delta Products, Inc., Mark Ten B Capacitor Discharge

       ignition System and a Solid State Products, Inc., model 200—IZN

       transistorized ignitiod'system.     Each system was used with the

       vehicle distributor breaker points,.

       The vehicle used in these tests was a 1968 Piymouth, 318 CID.       The

       vehicle‘s ignition system was put into a "tuned" condition and the

       tests were run with the timing, dwell, idle CO, and idle RPM set

       to thé vehicle manufacturer‘s specifications.     Raseline tests were

       then performed.     The devices were installed per the device manufac—

     The emission test data indicate that both devices produce slight

     reductions in hydrocarbons and very slight increases in oxides of

     nitrogen.       Carbon mohoxide emissions remained basical]y constant.

     All changes in emissions were considered insignificant and in the

     range of test repeatability.


     The coil voltage output was lower than what would be obtained with

     the vehicle in a fully "tuned" condition.              This was attributed to

     a degradation of the ignition wiring.             Howéver, the diagnosis checks

     indicated there was adequate voltage available to meet engine demand

     requirements for each of the three systems.                 The voltages measured

      at the higher engine RPM reflect the increases in voltage output

      at the higher engine speeds that are obtained with the capacitive

      discharge and transistorized systems.


IV.   Conclusions and Recommendations

      It is the staff‘s opinion that capacitive discharge and transis—

      torized ignition systems will not adversely effect motor vehicle

      exhaust emissions whenvevaluated with respect to the exhaust

      emissions obtained with a conventional ignition system of a "tuned"

      engine.   These devices may also have a beneficial effect in the

      contrbl of exhaust emissions in that they maintain the "tuned"

      condition of the engine for a longer period of time.   Therefore,

      capacitive discharge and transistorized ignition systems should be

      exempt from the prohibitions of Section 27156 of the Motor Vehicle
      Code.
