           EVALUATION OF THE MPG PERFORMANCE PRODUCTS COMPANY
                 "VARI—FLOW INJECTOR" IN ACCORDANCE WITH
      SECTION 2222, TITLE 13 OF THE CALIFORNIA ADMINISTRATIVE CODE



I.    INTRODUCTION

      MPG Performance Products of Chatsworth, California, has applied for

an exemption from Section 27156 of the California Vehicle Code {VC) for

an add—on device known as the "Vari—Flow Injector".     Exemption is sought

for all gasoline—powered motor vehicles.

      The device was evaluated by bench flow tests and back—to—back

Constant Volume Sampler, 1975 (CVS—75) emissions tests, and Highway Fuel
Economy tests (HFET}.
II.   DEVICE DESCRIPTION AND OPERATION

      The Vari—Flow Injector is a water injection system which sprays

water through a nozzle installed in the air cleaner housing into the air

horn (intake) of the carburetor.

      The major components of the system are a water reservoir, an electric

pump, a vacuum—actuated proportional control valve, and the spray nozzle.

Additional components are a water filter, oil pressure interlock switch,

manual on—off switch, and a solenoid valve (Figure 1).

      The Vari—Flow Injector is designed to inject water into the carburetor

inlet only during periods of increased demand for engine power, as evidenced

by Tow intake manifold vacuum.     When the engine is not running, an oil

pressure interlock switch disconnects the water pump and closes the

solenoid valve to stop the water flow.


      The Vari—Flow is available with five different size nozzles capable of

maximum flow rates ranging from 40 to 270 cc/min.       One nozzle, appropriate

to the size of the engine of the purchaser‘s car, is supplied with each

vari—flow unit.     Water flow starts at 11 inches of manifold vacuum and

increases to maximum flow rate at zero vacuum.

III. ARB TEST RESULTS

      At the request of the ARB staff, the applicant submitted four nozzles

for bench testing.     The Vari—Flow was assembled as shown in Figure 2

and the flow rates determined at appropriate manifold vacuum increments

are shown in Table 1.

       A plot of these data based upon second order polynomial equations
obtained by computer normalization is presented in Figure 3.               The large

difference between the .020" and the .025" nozzle was discussed with the

applicant.     The applicant then submitted a two—hole .020 nozzle for

testing.     This nozzle was not tested because it was apparent that the

flow rate would fit within the void area of the curves.

IV.    APPLICANT‘S TEST DATA

       The Air Resources Board specified two vehicles to be tested by the

applicant according to the CVS—75 test procedure.

       Data from the first vehicle was submitted on April 10, 1981.             The

applicant has not been able to complete the second vehicle in a timely

manner.

                                The submitted data are:

             Test Vehicle

             Year:                1980

*Rounded values.


     The staff finds that there is no significant increase in emissions

resulting from the installation of the YVari—Flow water injector on this

vehicle.   The absence of second vehicle data makes it impossible to

ascertain the effect of the Vari—Flow on larger vehicles.

V.   CONCLUSIONS AND RECOMMENDATIONS

     The staff finds no evidence that the Vari—Flow water injector will

have a significant adverse effect upon the emissions from motor vehicles

under 140 cubjc inch displacement.

     The staff,. therefore, recommends that Executive Order D—117 exempting

the Vari—Flow water injector from the prohibitions of VC 27156 be granted.
