State of California AIR RESOURCES BOARD August 3, 1979 Addendum to Staff Report Dated September 15, 1977 Evaluation of the Cagle Corporation Mark II Automatic Fuel Contro1" Device for Compliance with the requirements of Section 27156 of the Vehicle Code. Introduction 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 vehicles. 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 Vehicle #2 — 1979 Chevrolet Mailbu, License No. 604 WOF, 231 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 % Change —19.8 —34.1 0.0 +5.3 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 Fuel Fuel Pressure Manifold Pres§ure Pres§ure Vacuum #/in #/in 15 4.2 2. 55 1.65 13 4.2 2.50 1.78 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

Discussion 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.
