ABSTRACT:
This system is designed to increase gasoline mileage of automotive vehicles. Primarily, it consists of a two way selector valve connected to the vehicle's fuel pump and the carburetor, and also to a volume control valve connected to a heat exchanger that is connected to the air filter of the carburetor. The heat exchanger is mounted in the engine exhaust pipe as is a temperature sensor, and after the engine is started, the temperature sensor actuates a solenoid that rotates the selector valve to by-pass the liquid fuel into the heat exchanger which immediately vaporizes the liquid fuel as it passes into the air filter of the carburetor. The volume control valve is also coupled by linkage to the vehicle's accelerator pedal.
