A gasoline fume generator and mixer for use with an internal combustion engine is disclosed. Liquid fuel is fed through a metering valve and flows over a hot heat exchange unit which is maintained at a temperature above 200°F. by flow of engine coolant therethrough. The fumes generated by contact of the fuel with the heat exchange unit are mixed with air which is pulled into the generator tank by vacuum. This fume and air mixture is pulled out of the tank and into the carburetor to operate the engine in a conventional manner. A liquid level float actuated flow control device and a flap valve are provided to control the operation of the generator and a clean out plug is provided to allow periodic removal of portions of the liquid fuel which are not turned into fumes by the generator. An optional electric resistance heater is used to elevate the temperature of the liquid fuel entering the generator and mixer when needed, such as in cold weather and quick starts.

A gasoline fume generator and mixer for use with an internal combustion engine, said fume generator and mixer comprising: a generator tank having a bottom, side walls and a separable cover; a liquid riser pipe extending upwardly from said bottom of said tank, said riser pipe being supplied with liquid gasoline at a point adjacent said tank bottom; a metering valve in an orifice at an upper end of said riser pipe for regulating flow of the gasoline out of said riser pipe; a heat exchange unit spaced from, and surrounding said riser pipe, said heat exchange unit passing hot liquid coolant from the engine therethrough; means defining a first annular flow passage for said fuel, said heat exchange unit being positioned in said first annular flow passage, said liquid gasoline contacting said heat exchange unit to generate fumes; means for supplying air to said tank, said air mixing with said fumes and passing through an outer annular passage to an exit in said cover; and a fume filter interposed between said outer annular passage and said cover, said fumes and air passing through said filter for mixing and removal of entrained liquid particles in said fume and air mixture.
