ABSTRACT:
A fuel supply assembly providing vaporized fuel to an engine wherein a quantity of liquid gasoline fuel is controllably heated for a desired vapor emission from the liquid fuel, and a conduit arrangement conducts the vapor, intermixes it with ambient air and conveys the intermixture to the engine's combustion chamber. A sensor in the engine exhaust monitors the hydrocarbon content of the exhaust and control valving controls the vapor to air intermixture in response to the monitor for maintaining a desired intermixture that produces the desired hydrocarbon content.
