Device for improving gasoline fuel consumption

A fuel system for gasoline combustion engines wherein a carburetor is employed to deliver a combustible mixture to the intake manifold of the engine comprising a gasoline source and means for delivering a mixture of predominantly vaporized gasoline to the intake chamber of the carburetor, said means comprising a vaporizing chamber for holding liquid fuel, means for heating the liquid fuel in the chamber to generate a vapor phase therein above the liquid phase, a first conductor connected at one end to the bottom of the chamber, a second conductor connected at one end to the top of the chamber, a third conductor connected at one end to the carburetor, a Y connecting the opposite ends of the first and second conductors to the third conductor, said Y functioning to transmit liquid fuel from the first conductor to the third conductor and from thence to the carburetor while the engine is cold and for transmitting vaporized fuel from the second conductor to the third conductor and from thence to the carburetor when the engine is hot and wherein the Y functions as a venturi such that the flow of the vaporized fuel through the Y entrains a small amount of liquid fuel.
