      Introduction

      General Products Division, Sulf & Western Industries, Inc., Umon

      Springs, New York, has applied for exemption to the prohibftfons of

      Section 27156 of the Motor Vehiclie Code for the "Yoltronfx"

      transistorized—assisted contact ignition system. Sectian 27156 pro—
      hibits the installation of any device which reduces the effectiveness

      of motor vehicle emission control systems.        The applicant frtends

      to sell the device as an "»add—on" part to the standard ignitton

      system.


II.   System Description

      For a general description of transistorized ignition systems,

      see staff repeft "Evaluation of Capacitive Discharge and Transis—

      torized Ignition Systems for Compliance with the Requirements of

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


      The "Yoltronix" device consists of circuits for an amplifying tran—

      sistor and a power transistor.        The operation of the device relieves

      the contact points of making and breaking the full coflt current.



                                       1.


        "Yeltronix"                    '                             August 16, 1973




               The manufacturer claims that the device will maintain the proper

               dwell setting and timing for 50,000 miles.


        IHI.   Em#fsston Testing
               The "Voltronix" device was tested by the Air Resources Board Laboratory.

               The device was installed on a 1969 302 CID Ford.      The vehicle engine

               and exhaust systems were checked to insure proper operation.         For

               all tests, with and without the device, the engine settings were

               adjfusted to the vehicle manufacturer‘s specifications.


               Easeltne and device hot start CVS and 60 MPH cruise tests were per—

,              formed.     Fuel consumption was measured during the CVS test.     Engine

‘   .          RPM and total spark advance were recorded during the 60 MPH cruise

               test.     Open circuit spark voltages were noted at idle and at 3,000

               RPM.


               The results of the ARB tests are shown below:

    IV.   Concfusfons and Recommendations

          It fs the staff‘s opinion that the General Products Division/Guif &

          Western Industries, Inc., "Voltronix transistorized ignition system

          will not adversely effect motor vehicle exhaust emissions when

          eveluated with respect to the exhaust emissions obtained with a con—

          ventfonal ignition system of a "tuned" engine.   This device may also

          have a beneficial effect in the control of exhaust emissions [ if

          it matntains the "tdned" condition of the engine for a longer period

          af time.   Therefore, the "Voltronix" transistorized ignition system

          shauldrbe exempt from the prohibitions of Section 27156 of the Motor

          Y¥ehicle Code.                    -
