                                    SUMMARY



      Cagle Corporation requested an update of their existing exemption,
Executive Order No. D—75—6, from the prohibition in Yehicle Code Section 27156

for their "Cagle Mark II Automatic Fuel Control" fuel pressure regulator for

automobiles.   In particular, Cagle requested that the exemption be updated to

include all 1984 model—year gasoline—powered vehicles with conventional

carburetors.

      The company presented third party testimonials citing actual experienced

fuel economy results.   However, no laboratory test data are available to

substantiate any fuel benefit claims.

      Based on previous emissions tests performed on 1979 model—year vehicles,

and an engineering evaluation of 1979 through 1984 model—year vehicle‘s fue!l

systems, the staff has concluded that the Cagle fuel pressure regulator will

have no adverse effect on emissions from 1984 model—year automobile.

      The staff recommends granting Cagle‘s request to update the exemption.

 Evaluation of "Cagle Corporation Mark II Automatic Fuel Control" Device for
  Exemption from the Prohibitions in Vehicle Code Section 27156 in Accordance
— with Section 2222, Title 13 of the California Administrative Code



 I.    INTRODUCTION

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

 California 90806 requested by letter dated June 20, 1984, an update of the

 existing Air Resourceszoard's Executive Order No. D—75—6.    The applicant

 requested that the exemption from the prohibitions in Vehicle Code Section

 27156 for their "Cagle Mark II Automatic Fuel Control" device be updated to

 include all 1984 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.   CONCLUSION
       Previous Air Resources Board (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 model—year vehicles.

       Updates to include 1980, 1981, 1982 and 1983 model—year vehicles were

 granted on the basis that the vehicles fuel systems on 1979, 1980, 1981, 1982

 and 1983 were similar in design.
       An engineering evaluation of the vehicle‘s fuel system design on 1984,

 1983, 1982, 1981, 1980, and 1979 model—year vehicles indicates that the use of

 the Cagle device should not have an adverse effect on 1984 model—year vehicles.


III.    RECOMMENDATIONS

       Based on the above, the staff concluded that it is justified to grant

the Cagle Corporation an exemption from the prohibitions in Vehicle Code

Section 27156 for its "Cagle Mark II Automatic Fuel Control" device for 1984

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.   The staff, therefore, recommends that

Executive Order No. D—75—7 be issued.

IV.    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 fftting marked "PUMP" for connection to the fuel pump; and (3) an
outlet fitting market "CARB" for connection to the carburetor.   It is designed

to reduce the fuel supply pressure under Tow fuel demand conditions but still

maintain the required fuel flow to the carburetor under all operating modes.

The device is controlled by intake manifold vacuum operating on a spring

balanced Buna—N diaphragm.

       A cross sectional view of the device is shown in the Appendix.
       For a more detailed description of the device and its operation, the
reader is referred to ARB Staff Report dated December 17, 1980, entitled

"Cagle Corporation Mark I1 Automatic Fuel Control Device for Compliance with

the Requirements of Section 27156 of the Yehicle Code".

V.     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—75

                                          Exhaust Emissions
                                          (Grams per miles)           Fuel Economy
                                     HC            co           NOx      (mpg)
                  Baseline          0.492         3.37         2.46       15.2

                  Device            0.517         3.65         2.48       15.2

                                          (Grams per miles)           Fuel Economy
                                     HC          _CO            NOx      (mpg)
                  Baseline          0 .440        9.43         0.89       15.2

      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 (#/in2)                     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                        3.60              0.00


      Then on September 9, 1980, June 15, 1981,'    August 20 1982, and

August 9, 1983, the applicant requested, via letters, that the exemption be

updated to include 1980, 1981, 1982 and 1983 model—year vehicles,

respectively.   In response to those requests, the staff compared the vehicle‘s

fuel system design on some 1979, 1980, 1981, 1982 and 1983 model—year

vehicles.   Since no significant differences, that could adversely affect

exhaust emissions, were noted, no additional tests were requested for the

updates.

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

syfitem on some 1984, 1983, 1982, 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 perform any additional tests.

      The company presented third party testimonials citing actual experienced

fuel economy results.   However, no laboratory test data are available to

substantiate any fuel benefit claims.
