         Evaluation of the F. K. Products "Filter King Unit No. 5"
          Device in Accordance with Section 2222, Title 13 of the
                       California Administrative Code

       Introduction

       F. K. Products, 5 Cottingham Road, Toronto, 0ntar1o, Canada,
       M4V1B1, has appl1ed for an exempt]on for the "Fiiter King"
       device from the prohibitions of Section 27156 of Vehicle
       Code (See Exhibit A).    The device is manufactured by Alberto
       Malpassi, via Montebello, 56, 20038 Seregno, Italy. The .
       applicant is requesting that an exemption be granted for
       1978 and older gasoline powered vehicles.

II.    System Description

       The "Filter King" device is a fuel pressure regulator
       installed between the fuel pump and carburetor. It is designed
       to maintain the proper fuel flow to the carburetor at:optimum
       pressure. The applicant claims that by regu]at1ng the pressure
       to what is actually needed to supply the engine with enough
       fuel, the device eliminates most or all of the fuel pulsations
       emanat1ng from the fuel pump.    It also prevents excess gaso11ne
       from flowing into the float bow!l during pemods of heavy
       fuel bow1 slosh.   As a result, the carburetor is able to maintain
       a more uniform level of fue?t in the float bow!, thereby,
       reducing carburetor fiooding and increasing fuel economy.

       The device consists of an upper aluminum housing.that contains
       the fuel inlet and outlet, the valve, and the spring loaded
       diaphragm that regulates the opening and closing of the vaive,
       the lower glass container that holds the fuel and a high
       capacity fuel filter. Figure I shows a cross—section of
       the device.            ‘      ~                >

      Initially, fuel under pressure enters the pressure regulator
      into the glass compartment where the fuel is filtered. The
      proper amount of fuel is then metered past the valve, thence
      to the carburetor, by the action of the spring loaded diaphragm.

      When the fuel pressure under the diaphragm is high the diaphragm
      moves up causing the valve to seat against the port reducing
      the output pressure.   When the fuel pressure is low, the diaphragm
      moved down allowing the valve to open the port thus increasing      —
      the output pressure. The modulation of the diaphragm tends to
      smooth out the fue! pressure pulsation from the fuel pump. The
      pressure regulator output pressure can be adjusted by means
      of a screw located on the top of the aluminum housing.


III. System Evaluation

    A.   Applicant‘s Submitted Documents — The applicant claims
         that the installation of the device on the motor vehicle‘s
         fuel system will not have any adverse affect on exhaust
         emissions. The following supporting documents were
         submitted to the ARB.

          1.    Evaluation of Filter King Pressure Regulator
                dated January 3, 1975 by Professor Franz Huf of
               ~Polytechnic of Konstanz, West Germany. The tests
                were conducted on a chassis dynamometer. The report
                concluded that back—to—back tests, with no vibration    .
                induced on the vehicles, showed no change in emissions.
                With vibration induced on the vehicles {simuTlating
                actual road conditions), the emissions decreased
               with the installation of the Filter King device.    :
               Test data was not included in the report but would be
               made available upon request.

          2.   American Motors Corporation CVS—75 tests, dated
               September 30, 1977. Table I summarizes the test
               results. The test data indicate no significant
               change in the vehicle emissions when the Filter
               King was installed and set with fuel output pressure
                f 1.7 and 1.2 psig.

          3.   —Filter King is used as an original equipment part
               by several major ItaTian automobile manufacturers.      The
               fuel output pressure is preset in the factory to
               "optimize" the effectiveness of the fuel pressure
               regulation.                         .

         ARB Tests
         The ARB Laboratory evaluation of the device consisted
         of parametric pressure tests at different speed and
         engine loading conditions to determine the effect
         of the Filter King device on a typical carburetor.   The
         purpose was to identify any flow anomaTies which might
         indicate potential conditions which could adversely affect
         exhaust emissions.

         Tests were conducted on a 1976 Canadian Ford 302—2V non—
         catalyst engine installed on a chassis dyno test stand. The
         output fuel pressure of the device was adjusted by
         increments of 0.5 psig from maximum to minimum output
         allowed by the engine without causing fuel starvation.
         For each fuel pressure output setting, steady state
          tests were performed at Idle, 1,000, 1,500, 2,000 and
          2,500 rpm with the engine Toaded at 25% 50%, and maximum
          torque at each speed setting. Fuel flow rates and
         exhaust emissions were measured and compared to baseline
         data. Table I1 summarizes the pertinent test data.


           The test results show that the device can regulate
           fuel pressure from zero to fuel pump output pressure.
           The minimum pressure output that will not cause
           perceptible engine fuel starvation is 1.1 psig. At
           any one pressure setting the device regulates constant
           output pressure at all engine speed and Toading conditions.
           At any particular combination of engine speed and loading
           condition, varying the output pressure setting down to
           1.1 psig showed no change of fuel flow rate. This indicates
           the device pressure regulation down to 1.1 psig will not
           change the carburetor‘s air fuel mixtures, and consequently
           will not have any adverse affect on exhaust emissions.
           Measurements of HC, CO, and NOx exhaust emissions at these
           test conditions confirmed the above findings.

           Since the device will be marketed as an off—the—shelf item,
           the owner of the vehicle attempting to install the device
           may set output pressure beTow the acceptable level which
         . may result in an increase in vehicle emissions. This concern
           was relayed to the applicant. Subsequently, the applicant
           stated that the only device to be marketed in CaTifornia will
           be Unit No. 5. This unit will be equipped with a modulating
           spring that will not allow fuel output pressure to fall below
           1.25 psig. A sample of the spring was sent to the ARB
           for testing and was found to have a pressure cut off
           point of T.6 psig. Since the spring is designed to
           have a minimum cut—off point of. 1.25 psig, higher than the
           1.1 psig found to have no adverse interaction with the
           carburetor, the ARB antictpates no problem in the field
           due to the adjustable feature of the device.
IV.   Manufacturer‘s Claims

      The applicant claims the installation of the device on vehicles
      will improve fuel economy up to 15% by reducing carburetor
      flooding. This statement was based on tests conducted by    _
      Prof Franz Huf of Polytechnic of Konstanz, West Germany. These
      data, however, were not made available to the ARB. Extensive
      fuel economy tests by AMC (see Table—1) only showed an average
      of 6% improvement in fuel economy.                              '

      It is the staff‘s opinfion that the argument and supporting
      documents presented by the applicant regarding fuel economy
      benefits have merit and can be achieved under certain road
      driving conditions with the installation of the Filter King
      dévice.                                 c

      Conclusion and Recommendation

      The applicant submitted technical studies and emission tests
      showing that the installation of the "Filter King" device
      on typical in—use vehicles would not increase exhaust emissions.


ARB Laboratory filow tests showed that within the device
operating range, and under all engine speeds and Toading
conditions, the fuel flow rates wouldrnot change with the
installation of the "Filter King Unit No. 5". The device,
therefore, would not adversely affect the carburetor‘s
performance and hence no increase of vehicle emissions
would result from the use of the device. This was demonstrated
by the applicant‘s and the ARB emission test data.

Therefore, the staff —recommends that F.. K. Products be
granted an exemption from the prohibitions of Vehicle Code
Section 27156 for its "Fiter King Unit No. 5" for 1978
and older gasoline powered vehicles.
