                   Evaluation of RoinCo.
                         "5 tampede"
      Electronic Capacitive Discharge Ignition System
          For Exemption from the Prohibitions of
          Section 27156 of the Motor Vehicle Code


Introduction

RoIinCo., Edina, Minnesota, has applied for exemption from the prohibitions

of Section 27156 of the Motor Vehicle Code for the "Stampede" electronic

capacitive discharge system.   Section 27156 prohibits the installation

of any device which reduces the effectiveness of motor vehicle emission

control systems.   The app]icanf intends to sell the device as an "after—

market" part to augment the existing standard ignition system for all

1974 and older model year vehicles equipped with a 12—volt battery,

standard ignition coil, contact set, and negative ground except

those vehicles having an OEM solid state 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, dated February

17, i971.                                                             '


IT.       System Description

          For a general description of electronic capacitive discharge systems,

          see Staff Report "Evaluation of Capacitive Discharge and Transistorized

          Ignition Systems for Compliance with the Requireménts of Section 27156

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


          The "Stampede" device is a solid—state printed—circuit ignition system

      which consists of an inverter, a rectifier bridge, a storage capacitor,

          a coil, resistors, a silicon control rectifier and a switch.                        The switch

          is to allow converting back to the conventional ignition system (see

          Figure 1 below}.     The manufacturer claims that the ."Stampede" device

      can deliver up to 40 KV with a relatively short rise time in any climate,

          keeps the engine in a "just tuned" condition up to 50,000 miles, and

          improves gas mileage.

IV.   Staff Evaluation

      The applicant‘s data are considered within the normal instrumentation

      error except for the noticeable reduction in NOx emitted from the

      second vehicle which had relatively high baseline NOx emissions.


      The ARB data show    that the "Stampede" device has little or no effect

      on the centrifugal spark advance, the maximum available secondary

      voltage, the required secondaryvvo1tage, or the idle exhaust emissions.

      Based on the ARB test data, the manufacturer‘s claim that "Stampede"

      device ié capable of delivering up to 40 kilo—volts is not valid since

      insignificant change was observed with the device when compared with

      the baseline.   However, it was observed that "Stampede" device shortens

      the secondary voltage rise time.     The faster voltage rise rate enables

      the output energy to reach its maximum value in a relatively short
      time.   The spark duration is also reduced significantly to make the

      spark much hotter since the output energy is unchanged.     The spark

      duration, however, being significantly reduced is still far above the

      minimum limit required by auto manufacturers for combustion.


      Vehicles equipped with NOx emission control devices using a speed

      sensor such as the Dana or Carter device cannot be equipped with the

      "Stampede" device.     The speed sensor switch will interfere with the

      timing of the "Stampede" device and might cause excessive misfire.       The

      device will not function properly for vehicles eduipped with electronic

      ignition system whether it is a breakerless, capacitive discharge, or

      transistorized type.    The "Stampede" output voltage might overlap with

      the existing electronic ignition system causing damage to the engine‘s

      electrical system by overloading the ignition wires or coil.     It also

      could cause excessive misfiring due to erratic triggering from the points.


Conclusions and Recomfiendations

It is the staff opinion that RoInCo   “Stampede" e]ectronjc capacitive

discharge ignition system will not adveréely affec£ motor vehicle

exhaust emissions when evaluated with respect to the exhaust ehissions

obtained with a conventional ignition system of a "tuned" engine.      This

device may also have a beneficial effect in the control of exhaust

emissions in that the device may maintain the "tuned" condition for a

']onger period of time.   Therefore, the "Stampede" electronic capacitive

discharge ignition system should be exempt from the prohibitions of

Section 27156 of the Motor Vehicle Code for 1974 and older model—year
vehicles equipped with a 12—volt battery, standard ignition coil,

contact set, and negative ground except the following:


1.   Vehicles originally equipped with an electronic ignition system

     whether it is a breakerless, capacitive discharge, or transistorized

     type.

2.   All 1966—1970 model—year vehicles equipped with a Dana or Carter NOx

     retrofit device using an electronic speed sensor.
