State of California AIR RESOURCES BOARD Staff Report October 23, 1981 Evaluation of the Western Carbide‘s "Fuel Miser" Water Injection System in Accordance with Section 2222, Title 13, of the California Administrative Code. I. INTRODUCTION Western Carbide of Stanton, California, has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code for an add—on device known as the "Fuel Miser" water injector. This exemption is being requested for all 1981 and older gasoline—fueled engines. The device was evaluated by back—to—back Constant Volume Sampler 1975 (CVS—75) tests. II. DEVICE DESCRIPTION AND OPERATION The "Fuel Miser" is a vacuum—controlled water injection system. The major components of the system are two nozzles which mount in the spacer plate under the carburetor, a water bag, and a control valve, The control valve (Figure 1) consists of a vacuum—actuated diaphragm which is connected to a manifoid vacuum source and a "reverse taper" needle valve which controls the water flow. The needle is calibrated such that no water flow occurs during idle, deceleration, and mild acceleration. The vaive opening is then inversely proportional to manifold vacuum.

III. APPLICANT‘S TEST RESULTS The applicant submitted hot start CVS—72 data from a 1978 Datsun 280Z and cold start CVS—75 data from a 1981 Mercury Zephyr. These data are: Vehicle No. 1, 1978 Datsun 2807, 2.8L automatic transmission, VIN HL530383338, odometer 36505: Hot Start CVS—72 Test Emissions (g/mile) Fuel Economy HC CO NOx mi/gal Baseline 0.47 10.62 2.16 15.2 Device 0,.29 4.73 1.99 15.2 % Difference —38.3 —55,5 —7.9 —— Vehicle No, 2, 1981 Mercury Zephyr, 3.3L automatic transmission, VIN 1MEBP 73B 7BK 63, odometer 5018: Cold Start CVS—75 Test Emissions (gm/mile) Fuel Economy wC co NOx mi/gal Baseline .29 2.58 42 17.4 Device .26 _2.84 .45 17.0 % Difference ~10.3 +10.1 +7.1 —2.4 IV. DISCUSSION The principle of operation of the "Fuel Miser" control valve avoids the major problem (encountered in vacuum—operated water injectors) of

flooding the engine with excessive amounts of water during low demand periods. Although the device is called the "Fuel Miser", no other claim of fuel economy is being made,. The CVS test data indicates no significant increase in emissions or fuel economy occurred as a result of the installation of the "Fuel Miser" on either carburetor—equipped or fuel injected cars. Vv. CONCLUSION AND RECOMMENDATION The staff finds no evidence to indicate that the "Fuel Miser" water injection system will have a significant adverse effect on emissions from a motor vehicle. The staff, therefore, recommends the approval of Executive Order No. D—116 exempting the “Fue] Miser" water injector from the prohibitions of Vehicle Code Section 27156.
