A novel system for introducing a combustible liquid fuel into a gasoline combustion engine to obtain substantially perfect combustion and thereby prevent pollution, which system comprises heating means for elevating the temperature of the liquid gasoline fuel above its critical temperature, thereby converting it to its gaseous state; pressure means for providing a positive pressure as the liquid fuel is transported to the heating means; and means for discharging and rapidly expanding the gaseous fuel into the mixing chamber of the engine where it is admixed with air to provide a combustible mixture for burning and operation of the engine, the pressure means providing a pressure sufficient to maintain the fuel in its gaseous state immediately after it is discharged from the heating means into the mixing chamber.

A combination of a gasoline internal combustion engine powered by a flammable gasoline fuel and having mixing chamber means wherein said fuel is admixed with air to form a combustible mixture for burning and operation of said engine; and means for introducing said air and fuel into said mixing chamber means to provide said combustible mixture, said means for introducing said fuel comprising: (1) a source of flammable gasoline fuel and an air supply source; (2) a pressure pump; (3) conduit means for transporting said fuel in a liquid state from said fuel source to said pump; (4) a heat exchanger adapted to heat said liquid fuel above its critical temperature, thereby converting said fuel to a gaseous state; (5) conduit means for transporting at least a portion of the fuel from said pressure pump under pressure to said heat exchanger; and (6) expansion valve means through which said fuel in said gaseous state is discharged, said expansion valve means being adapted to regulate the rate of discharge of said fuel in said gaseous state into said mixing chamber means, said pressure from said pump being maintained until said fuel in said gaseous state is discharged from said heat exchanger and rapidly expands into said mixing chamber means for admixture with said air to form said combustible mixture.
