Evaluation of "Cagle Corporation Mark II Automatic Fuel Control" Device
for Compliance with the Requirements of Section 27156 of the Vehicle Code



I.    INTRODUCTION

      Caglie Corporation of 2667 East 28th Street, Suite 517, Long Beach

California 90806 requested by letter dated June 15, 1981    (See Appendix A)

an update of the existing Air Resources Board‘s Executive Order No. D—75—3.

The applicant requested that the exemption from the prohibitions of Vehicle

Code Section 27156 for their "Cagle Mark II Automatic Fuel Control" device

be updated to include all 1981 and older model—year motor vehicles that

are powered by gasoline engines with conventional carburetors and mechanical

or electrical fuel pumps with and without fuel recirculation systems.

II.   DEVICE DESCRIPTION AND OPERATION

      The "Cagle Mark II Automatic Fuel Control" is a fuel pressure regulator

installed between the fuel pump and the carburetor.     It has three external

fittings: (1) a fitting at the top for measuring intake manifold vacuum;
(2) an inlet fitting marked "PUMP" for connection to the fuel pump; and
(3) an outlet fitting marked "CARB" for connection to the carbuļ¬etor.      It

is designed to reduce the fuel supply pressure under low fuel demand

conditions but still maintain the required fuel flow to the carburetor

under all operating modes.     The device is controlled by the intake mani—

fold vacuum operating on a spring balanced Buna—N diaphragm.


     A cross sectional view of the device is shown in Appendix B.

     For a more detailed description of the device and its operation, the

reader is refered to Air Resources Board Staff Report dated December 17,

1980, titled "Cagle Corporation Mark II Automatic Fuel Control Device

for Compliance with the Requirements of Section 27156 of the Vehicle Code".

III. DISCUSSION
     Prior to issuing Executive Order No. D—75—2 (which exempted 1979 and

older model—year vehicles) the staff performed comparative exhaust emissions

tests on a 1979 Ford Fairmont with a 302 CID engine and on a 1979 Chevrolet

with a 231 CID engine.       The results of these tests were as follows:



                             1979 Ford Fairmont
                     ARB Emission Data — Cold Start CVS

                                   HC            CO       NOx

                  Baseline        0. 492        3. 37   2.46

                  Device          0.517         3.65    2.48



                             1979 Chevrolet Malibu
                    ARB Emission Data — Cold Start CVS

                                           Grams_per miles
                                   HC            CO      NOx

               Baseline           0. 440        9.43    0.89

               Device           _ 0.353         6.21    0.89


     In addition, fuel pressure measurements were taken before and

after the regulator for various manifold vacuums.   The results were

as follows:

Manifold Vacuum            Fuel Pressure (#/ing)                Change
 (inches Hg)        Before Regulator    After Regulator       in Pressure

     15                  4.2                 2.55                1.65

     13                  4.2                 2.50                1.70

     11                  4.2                 2.50                1.70
      9                  4.2                 3.05                1.15

      7                  4.2                 3.70                0. 50
      5                  4.2                 3.88                0.32
      3                  3.6                 3.6                 0



     Then on September 9, 1980, the applicant requested, via letter, that

the Executive Order be updated to include 1980 model—year vehicles.      In

response to that request, the staff compared the vehicle‘s fuel system

design on some 1979 and 1980 model—year vehicles.   Since no significant

differences, that could adversely affect exhaust emissions, were noted, no

additional tests were requested for the update.

     In response to this request, the staff compared the vehicle‘s fuel

system on some 1981, 1980 and 1979 model—year vehicles.    No significant

differences were noted between the vehicle‘s fuel system design even

though newer cars tend to operate more fuel efficient.    The staff,

therefore again, did not recommend or performed any additional tests.


v.   CONCLUSION AND RECOMMENDATION

     Previous ARB confirmatory emissions tests showed that the use of

the "Cagle Mark II Automatic Fuel Control" device did not have an adverse

effect on the exhaust emission control system of 1979 model—year vehicles.

The staff then granted an exemption from the Vehicle Code for 1979 and older.

     An update to include 1980 model year vehicles was granted on the basis

that the vehicles fuel system on 1979 and 1980 were similar in design.

     An engineering evaluation of the vehicle‘s fuel system design on

1981, 1980, and 1979 indicate that the use of the Cagle device should not

have an adverse effect on 1981 model—year vehicles.

     Based on the above, the staff concluded that granting the Cagle

Corporation an exemption from the prohibitions of the Vehicle Code Section

27156 for its "Cagle Mark II Automatic Fuel Control" device for 1981 and

older model vehicles that are powered by gasoline engines with conventional

carburetors and mechanical or—electrical fuel pumps with or without fuel

recirculation system is justified.   The staff, therefore, recommends that

Executive Order No. D—75—4 be adopted.
