Harvey, R

In combination with a gasoline-powered internal combustion engine, and fuel supply, an apparatus is described for injecting a fuel mixture of vaporized fuel, fuel, steam and air into the engine carburetor which consists of: heated means for vaporizing fuel comprising: a closed chamber having a fuel inlet, a vapor outlet, a perforated septum lying horizontally across the lower half of the chamber; a pipe passing through the chamber through which hot fluid derived from the engine cooling system is circulated; and means associated with the inlet for spraying fuel against the septum; means for generating steam in proportion to the manifold vacuum created by the engine, wherein the means for generating steam comprises: a supply of water; a variable output water pump; means for controlling the output of the water pump in response to the intake manifold vacuum generated by the engine; and a heat exchanger to apply heat from the engine's exhaust manifold to the water delivered by the water pump, the heat exchanger having a conduit leading from the water pump to the carburetor; and the conduit passing through the heated means and subsequently being intimately wrapped around a portion of the exhaust manifold of the engine means; for delivering a portion of the fuel supply through the heated means, comprising: a metering valve having an inlet port and first and second outlet ports; an adjustable gate controlling the distribution of fuel admitted through the inlet between the outlet ports; ducting means connecting the inlet port to a pressurized fuel supply, the first outlet port to the fuel inlet of the carburetor and the second outlet port to the fuel inlet of the chamber; and conduit means for delivering steam from the means for generating and vapor from the means for vaporizing into the carburetor.
