                           AIR RESOURCES BOARD

                              March 2, 1981

Evaluation of the Techimport Limited "Filter King Model No. 4" and "Filter
King Model No. 5" for Compliance with the Requirement of Section 27156
of the Vehicle Code.


      Techimport Limited, of 119   Glen Road, Toronto, Canada MAW 2W1, has

requested by letter dated January 31, 1981 (See Appendix A) an update to

the existing Air Resources Board‘s Executive Order D—79—2.    The applicant

requested that the exemption from the prohibitions of Vehicle Code (V.C.)

Section 27156 for their "Filter King Model No. 4" and "Filter King Model

No. 5" fuel control device be updated to include all 1981 and older model

year gasoline—powered vehicles with conventional carburetor systems.

      Section 27156 of the V.C. prohibits the installation, sale, or

advertisement.of any device which alters the performance of the vehicle‘s

emission control system.   The Air Resources Board (ARB) is empowered to
exempt any device from this prohibition if it can be shown that the

installation of the device will not reduce the effectiveness of the existing

emission control system.

      The "Filter King" device is a fuel pressure regulator installed

between the fuel pump and the carburetor.     It is designed to maintain the

fue! pressure in the carburetor at optimum Tevels. The applicant claims:

      1.   By regulating the fuel pressure to supply the engine with the

required amount of fuel, the device eliminates most or all of the fuel

pulsations emanating from the fuel pump.

     2.      The device also prevents excess gasoline from flowing into the

float bow] during periods of heavy fuel bowl sjosh.

     3.      As a result, the carburetor is able to maintain a more uniform

level of fuel in the float bowl, thereby, reducing carburetor flooding and

increasing fuel economy.

     The device consists of an upper aluminum housing and a lower glass

container.     The aluminum housing contains a fuel inlet, a fuel outlet, a

vaive, and a spring loaded diaphragm that regulates the opening and closing

of the valve.     The lower glass container holds the fuel and a high capacity

fuel filter.     Figure I shows a cross—section of the device.

     Inititally, fuel from the fue! pump under pressure enters the glass

compartment where the fuel is filtered.     The amount of fuel that passes the

valve and thence to the carburetor is metered 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 thus reducing

the output pressure.     When the fuel pressure is low, the diaphragm moves

down allowing the valve to open the port thus increasing the output

pressure.    The modulation of the diaphragm tends to smooth out the fuel

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.


     The applicant submitted emissions test data for the original application.

The tests, conducted by AMC, were performed on a 1978 AMC vehicle.     The

data in Table 1 shows that the device has little effect on emissions at

low outlet pressures of 1.2 and 1.7 psig.

      The ARB evaluated the device during the orignal application.    The

evaluation consisted of parametric pressure tests at different speed

and engine loading conditions on a typical 2 barrel carburetor.      The

results in Table 2 indicated that the amount of fuel delivered to the test

carburetor and emissions were unaffected due to fuel pressure differences.

      The Air Resources Board staff report titled "Evaluation of the F. K.

Products Filter King Unit No. 5 Device in Accordance with Section 2222,

Title 31 of the California Administrative Code", dated February 24, 1978,

contains a detailed description of the tests performed.

      Based on the above data the Filter King does not seem to have any

effect on fuel delivery and on exhaust emissions of an automobile engine

equipped with a conventional carburetor.   Since the "engine out" emissions

are not changed, the operation and the efficiency of a three—way catalyst

does not change either.

      Also when the fuel delfvery rate remains unchanged, the float level

will not change.   An air/fuel ratio feedback control system on late model

year cars draws fuel from a bow!l in the same way as a conventional car—
buretor, and should not be affected if the float level does not alter.

      The previous test data submitted by the applicant and generated by ARB

showed that the use of the "Filter King" device did not have any effect
on the exhaust emission control system of 1978 model year vehicles.

     Based on the test data Techimport Limited was granted an exemption

{Executive Order D—79 dated April 17, 1978) from V.C. 27156 for 1978 and

older gasoline powered vehicles.   The exemption was later updated to

include 1979 model year gasoline—powered vehicles (Executive Order D—79—1,

dated January 12, 1979) and for 1980 model year gaso]ine-powered'Vehicles

(Executive Order D—79—2, dated March 6, 1980).

     The staff found no significant difference between the 1981 and 1978

vehicle‘s fuel system design and the engine—out emissions are not affected

by the use of the Filter—King device.

     Based on the above, the staff concliuded that the installation of the

"Filter King Model No. 4" or "Filter King Model No. 5" fuel control device

will have no effect on vehicle exhaust emissions.   The staff recommends
that Techimport‘s exemption, Executive Order No. D—79—2, be updated to

include 1981 and older model year gasoline—powered vehicles with conventional

carburetor systems.   The staff, therefore, recommends that Executive Order

D—79—3 be adopted
