ABSTRACT:
A device for attachment to a carbureted automobile engine for improving its performance, both by reduction of pollutants by obtaining more complete burning of the fuel and by obtaining better gasoline mileage, especially in city and other stop-start driving. The fuel is passed into a heat exchanger between the fuel pump and the carburetor. The heat exchange utilizes the water pump and water from the radiator in conjunction with a heat sensor located close to the carburetor to feed the gasoline to the carburetor at temperatures depending on the prevailing weather and climate, i.e., at about 110.degree. to 120.degree.F. in winter in northern California and about 125.degree. to 145.degree.F. in the summer there. The temperature is kept within a range of 5.degree.-6.degree.F. A pressure regulator is interposed between the heat exchanger and the heat sensor for regulating the pressure of the fuel fed to the carburetor, so that it will be about 3 pounds per square inch.
