           Evaluation of thé Environmental Gasmizer Products, Inc.
                                  "Gasmizer"
                    for Exemption from the Prohibitions of
                   Section 27156 of the Motor Vehicle Code


          Introduction

          Environmental Gasmizer Products, Inc. of San Diego, California ha§ applied

          for exemption from the prohibitions of Section 27156 of the Vehicle Code

          for its "Gasmizer" reed type air bleed valve.      This section prohibits the

          installation of any device which reduces the effectiveness of the motor

          vehicle emission control system.     The applicant is requesting the exemp—

          tion be granted for the two following groups:

      a.       All 1970 and older model—year vehicles.

          b.   All 1971 and newer model—year vehicles.


II.       Dévice Description and Function

          The device is a pressure sensitive reed type air bleed valve which is

          installed in the line connecting the positive crankease ventilation vailve

          and the intake manifold.     When the vehicle operates under high load or

          acceleration conditions, the device will admit air into the positive crank—

          case ventilation line.     As the valve is fiorma?iy open, a slight intake

          manifold vacuum is required to close the valve.     The manufacturer states

          that this condition exists, over the negative pressure range of 0.0

          inches to 4.5 in. Hg.    The device has a pressure sensitive reed valve which
      y


"GASMIZER"                                                        Aprit 12, 1974


    stops the flow of the external air into the intake manifold when

    the vehicle is idling, cruising, or decelerating and the vacuum at

    the "Gasmizer" valve is greater than 4.5 in. Hg.     For positive

    pressure such as the case of backfiring, the "Gasmizer" valve will

    also prevent gases from escaping through the valve to the atmosphere.


III. System Evaluation

    A.   Applicant‘s Data

         The applicant has submitted the following:

         1)   Scott Research Laboratory data report No. 2189 O1 10 73 entitled

              "Bench flow test of a Combustion Regulator and an Air Jet".

              The bench flow data submitted is a comparison between the

              "Combus tion Regulatof" and the "Air Jet" air bleed valves.   This

              data did not show the maximum flow capability of the valve at a

              manifold vacuum above 2.0 in. Hg.   Below 2.0 in. Hg the flow range

              was similar to the Air Jet valve.

         2)   Scott Research Laboratory data report No. 2190 01 10 73 entitled

              "Exhaust emission and fuel consumption evaluation of a Gasmizer".

              This report shows exhaust emissions obtained from hot CVS tests

              performed on the following vehicles:

              (a)   1973 Ford Torino, 350 CID, 2 Bbl. Carb., Auto Trans. (826 GHL}.

              {b)   1965 Dodge Dart, 273 CID, 2 Bb]..Carb., Auto Trans. (PHT 166).

              (c)   1967 Chevrolet Impala, 327 CID, 2 Bbl. Carb., Auto Trans. (TVS 672).

              The data from these tests are shown in Table I.


"GASMI ZER"                                 -                      April 12, 1974


        In general, the emissions were reduced when using the "Gasmizer"

       device.   The hydrocarbons were reduced by an average of 5.2%, the

       carbon monox%des were reduced by an average of 16.6%, but the oxides

       of nitrogen were increased by an average of 4.9%.

       The increase in ~HC and NOx are within normal test variability.       Therefore,

       these data show that the installation of the "Gasmizer" device will have

       no adverse effects on existing exhaust emission control system of a

       motor vehicle.


       Bench Flow Test Performed by ARB

       The Air Resources Board performed bench flow tests at its laboratory

       to verify the applicant‘s claims.        The test data is shown in Figure 1.


       This ARB data did not show good correlation with that presented by the

       applicant due to a difference in test method.


       The ARB bench flow test measured the air bleed rate by varying the

       vacuum downstream from the vaive with the PCV inlet port closed.        The

       ranges of vacuum used in the test are those experienced during normal

       engine operation.   A maximum flow rate of 2.3 CFM was observed when the

       vacuum varied bétween 0 in. to 6 in. Hg.        Under normal road load, vehicles

       operate in this vacuum range for a minimal period.       The staff considers

     \ the volume of air that flows through the "Gasmizer" into the intake mani—

       fold during this period to be insignificant.       No flow rate was observed

       when vacuum exceeded 10 inches Hg.       The data obtained show that the device

       meets the maximum flow criteria established by the ofB for all engine

       sizes.


"GASMIZER®"                                                  ‘April12, 1974


    C.    Fuel Evaporative Emissions

         \Based upon similar devices tested previously by the ARB, the staff

         does not expect significant fuel vapor losses escaping to the atmosphere

          through the "Gasmizer".


IV. Conclusion and Recommendation
    The air flow permitted by the "Gasmizer" is within the established

    criteria for all natural aspirated gasoline engines with carburetor fuel

    delivery systems.


    Therefore, the staff recommends that the "Gasmizer" air bleed vaive

    manufactured by Environmental Gasmizer Products, Inc. of San Diego,

    California be granted an exemption from the prohibitions of Section

    27156 for 1974 and older mode]_year vehicles.
