ABSTRACT:
A fuel mixture injection apparatus associated with the carburetor of an internal combustion engine designed to improve engine efficiency by delivering a mixture of vaporized gasoline, steam and air directly to the carburetor. A portion of the fuel supplied by the fuel pump is diverted through a metering valve into a closed chamber where it is sprayed over a perforated vaporizer grid heated by a double loop of copper tubing through which hot engine coolant is ducted. The gasoline vapor is then ducted either into the carburetor or directly into the intake manifold. Simultaneously, water from a reservoir flows through a line in response to engine load and temperature conditions. The line passes through the closed chamber where the water is preheated. The line then leads to a heat exchanger connected to the engine's exhaust manifold where the water is converted to steam. From the heat exchanger, the steam is ducted either into the carburetor or directly into the intake manifold.
