METHOD AND APPARATUS FOR VAPORIZING FUEL

摘要

A method and apparatus is provided for the vaporization of liquid hydrocarbon fuel in a closed system prior to its entry into an internal combustion engine's combustion chambers in amounts proportional to the acceleration level of the engine. The apparatus is a fuel vaporizer (10) interposed between an engine's fuel injection system and combustion chambers and forms a canister housing. Liquid fuel enters via an inlet (16) in the housing, is vaporized by heating it to boiling and is drawn out of the canister via an outlet (26) under a partial vacuum to the combustion chambers of the engine. The system is closed except for a vacuum connection with the engine's combustion chambers. Heating means (12) are provided to heat the fuel to boiling without heating it to its flash point, thus avoiding its pre-ignition.
