ABSTRACT:
Apparatus for producing a combustible fuel/air mixture in which the fuel is completely vaporized for operating an internal combustion engine. Exhaust gases from the engine (40) pass through a heating manifold (8) in a vaporization chamber (2) to raise the temperature of a body of volatile liquid fuel in the bottom of the chamber. An air stream is also heated by passing it in heat exchange relation with hot exhaust gases from the engine. The stream of heated air is then drawn through an enclosed vapor space (6) at the top of the vaporization chamber, and fuel vapors are entrained therein. The fuel vapor-containing air stream is then mixed with additional air in a mixing chamber (26) to produce a combustible fuel/air mixture which is conveyed to the intake manifold (38) of the engine. Safety screens (64) are provided to prevent entry of sparks or flame into the fuel chamber.
