STATE OF CALIFORNIA AIR RESOURCES BOARD 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 AVUGUST 19, 1983

Issue Date: August 19, 1983 EVALUATION OF "CAGLE CORPORATION MARK II AUTOMATIC FUEL CONTROL® DEYICE FOR EXEMPTION FROM THE PROHIBITIONS IN VEKHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13 OF THE CALIFORNIA ADMINISTRATIVE CODE by Mobile Source Control Division State of California Air Resources Board 9528 Telstar Avenue E1 Monte, California 91731 (This report has been reviewed by the staff of the California Air Resources Board and approved for publication. Approval does not signify that the contents necessarily reflect the views and policies of the Air Resources Board, nor does mention of trade names or commerical products constitute endorsement or recommendation for use.)

SUMMARY Cagle Corporation requested an update of their existing exemption, Executive Order No. D—75—5, from the prohibition in Vehicle 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 1983 model—year gasoline—powered vehicles with conventional carburetors. Based on previous emissions tests performed on 1979 model—year vehicles, and an engineering evaluation of 1979 through 1983 model—year vehicle‘s fuel systems, the staff has concluded that the Cagle fuel pressure regulator will have no adverse effect on emissions from 1983 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 égggrdance with Section 2222, Title 13 of the California Administrative I. INTRODUCTION Cagle Corporation of 2667 East 28th Street, Suite 517, Long Beach California 90806 requested by letter dated August 9, 1983, an update of the existing Air Resources Board‘s Executive Order No. D—75—5. 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 1983 and older model—year motor vehicles thaf are powered by gasoline engines with conventional carburetors and mechanical or electrical fue] 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 modelT—year vehicles. The staff then granted an exemption from the Vehicie Code for 1979 and older model—year vehicles. Updates to include 1980, 1981, and 1982 model—year vehicles were granted on the basis that the vehicles fuel system on 1979, 1980, 1981 and 1982 were similar in design. An engineering evaluation of the vehicle‘s fuel system design on 1983, 1982, 1981, 1980, and 1979 modeT—year vehicles indicate that the use of the Cagle device should not have an adverse effect on 1983 model—year vehicles.

III. RECOMMENDATIONS Based on the above, the staff concluded that granting the Cagle Corporation an exemption from the prohibitions in Vehicle Code Section 27156 for its "Cagle Mark II Automatic Fuel Control" device for 1983 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—6 be adopted. 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 fitting 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 low 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 II Automatic Fuel Control Device for Compliance with the Requirements of Section 27156 of the Vehicle 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 2.

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 cCO NOx (mpg) Baseline 0.492 3.37— 2.46 15.2 Device 0. 517 3.65 —2.48 15.2 1979 Chevrolet MaTibu ARB Emission Data — Cold Start CVS—75 Exhaust Emissions (Grams per miles) Fuel Economy HC Co NOx {mpg) 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: Manifold Yacuum Fuel Pressure (#/in?) Change (inches Hg) Before Regulator After Requlator 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 C 3.6 3.60 _ 0.00

Then on September 9, 1980, June 15, 1981, and on August 20, 1982, the applicant requested, via letters, that the exemption be updated to include 1980, 1981 and 1982 model—year vehicles, respectively. In response to those requests, the staff compared the vehicle‘s fuel system design on some 1979, 1980, 1981 and 1982 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 system on some 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.
