Abstract
A carburetion system for an internal combustion engine includes fuel vaporizing gun which operates as a heat exchanger with heat from the engine exhaust manifold. The system may be manually or automatically operative when hot exhaust gases from the engine heat the gun to sufficient temperatures for vaporizing the fuel. A vapor fuel shut-off valve positioned on the vapor line to the engine intake ports regulates the air to gas mixture to a ratio of between 15 and 16 to 1, for maximum combustion, increased fuel mileage and reduced emissions.
