      The Cagle Corporation by letter dated November 7, 1978, (Exhibit A)

      has requested an update of their Executive Order D—75—1 to include

      the 1979 and older model year vehicles.       A description of the de—

      vice, its operation, previous test data, and a discussion of the
      theory will be found in the attached Staff report dated September

      15, 1977.

II.   Air Resources Board LaboratoryTests

      Since the late model vehicles tend to run on leaner air—fuel

      ratios, and the emission control systems are more complex,

      the staff thought it advisable to perform tests on 1979


      The following tests were run.

      Vehicle #1.

      This was a 1979 Ford LTD Landau with .a 302 CID engine and a

      variable venturi carburetor.    Two devices were run on this

      vehicle since there was a stalling problem at idle during

      the cold start tests after the devices were installed.      Two

      starts were required.

The results were as follows:

Device #1

                                 hC          co        NOx        mpa
     Baseline                    0.313        0. 34     1.59      13.0

     Device                      0.283        1.52      1.55      13.0

     % Change                   —9.6         +347.1    —2.5        0.0

The increase in CO was attributed to the stalling problem and

therefore the tests were repeated using a second device.

Device #2

                                 hC          co        NOx       MPe
     Baseline                    0.233        0.66      1.53      12.9

     Device                      0. 348      1.56       1.57      12.8

     % Change                  +49.4         +136.4    +2.6       —0.8

The increase in HC and CO was again attributed to the stalling

problem during the device test.        In order to eliminate any chance

that it might be the vehicle that was at fault, a second vehicle

was tested using the second device:

Vehicle #2 — 1979 Ford LTD, 302 CID engine with a variable

venturi carburetor, License #811 VPE.

The results were as follows:

                                hC           co        NOx       MPG
     Baseline #1                0.527        1.09      1.47       13.2

     Baseline #2                0.638        0.84      1.64      12.9

     Average                    0.582        0.97      1.55      13.1

                               hC         co           NOx      MP&
          Device               0.6504     1.45         1.54     13.2

          % Change            +3.9      +51.5          0.0      +0.8

     This vehicle also stalled during the cold start test with the

     device.   Three starts were required.

     Based on the above test results which showed increased emissions,

     the application was denied (Exhibit B)

III. Applicant‘s request for reconsideration

    The applicant requested reconsideration of its application and

    submitted the following test data in support of this request

     {Exhibit C)

    Laboratory — W. R. Grace, Garden Grove, CA

    Test Vehicles — 1979 Ford Granada 302 CID, Vehicle #172600

                       (variable venturi carburetor)
                     — 1979 Chevrolet E1 Camino 305 CID Vehicle # 410354

                               HC         co           NOx      mPa
          Ford Baseline       0. 230     0. 850        1.139    14. 367
          Device              0. 260     0. 900        1.219    14. 306
          % Change             +13.0      +5.9         +7.0     —.4

          Chevrolet Baseline 0.410        4. 320       1.269    14.534

          Device              0. 460      2.620        1. 252   14.285

          % Change             +12.2      —39.4        —1.3     —1.7

      No stalling problems were noted.    Emissions could be considered

      within acceptable testing variation lTimits.

IV.   Air Resources Board Confirmatory Tests

      In order to confirm the W. R. Grade data, the applicant was

      requested to submit the same Ford vehicle tested by W. R.

      Grace to this laboratory for confirmatory testing.     The

      results were as follows.

                                    hC          co         NOx       mP6
           Baseline                  0.259       1.69      1.18      14.2

           Device                   0. 255       1.43      1. 20     14.2
           % Change                —1.5        —15.4     +1.7         0.0

      No stalling problems and no increase in emissions were noted.

      Since both the vehicle and the device were submitted by the

      applicant, the staff felt that additional tests were needed.

      By adjusting the float in the carburetor fuel bow!, the results

      could be altered to favor the device.    The staff therefore chose

      the devices to be tested from the applicants inventory at the

      factory and the vehicles were rented from Hertz.

      The results of these tests were as follows:

      Vehicle #1 — 1979 Ford Fairmont, License No. 637 WCH,

      302 CID engine with a variable venturi carburetor.

                                 HC         CO            NOx             MPG

     BaseTine                    0. 492     3.37          2.46            15.2

     Device                      0.517      3.65          2. 48           15.2

     % Change                   +5.1       +8.3          +0.8              0.0

CID engine, 6 cyl.

                                hC          co           Nox              mpa
     BaseTine                    0. 440     9.43          0.89            15.2

     Device                      0.353      6.21          0.89            16.0

In addition fuel pressure measurements were taken before and

after the regulator for various manifold vacuums.          The results

were as follows for the Chevrolet vehicle.

                         Normal             RegulTated            Change in

      7                  4.2               3.70                   0.50

      5                  4.2                3. 88                 0. 32

      3                  3.6                3.6                   0


      The staff is at a loss to explain the stalling problem in the

      first two vehicles tested.   However subseqeunt tests did not

      show any such problem and the vehicle emissions were within

      acceptable Timits.   The device did not show any significant

      increase in miles per gallon.

VI.   Conclusion

      Based on the majority of the test results and an engineering

      evaluation, the staff feels that the use of the "Cagle Mark II

      Automatic Fuel Control" Device should not have an adverse effect
      on the exhaust emission control systems of vehicles with conventional

      or variable venturi carburetors and mechanical or electric fuel pumps

      with and without recirculation systems.

VII. Recommendation

      In view of the above discussion and conclusion the staff feels
      that granting the Cagle Corporation an exemption from the

      prohibitions of Section 27156 of the California Vehicle Code

      for its "Cagle Automatic Fue! Control" device for installation

      on 1979 and older model vehicles using conventional or variable

      venturi carburetors with mechanical or electric fuel pumps with

      and without recirculating systems is justified.   The staff

      recommend adopting Executive Order D—75—2.
