Abstract
A fuel vaporizer for an internal combustion engine comprises an air/fuel heating and mixing chamber which vaporizes liquid hydrocarbon fuel to a heated, dry vaporous state and mixes it with heated air for introduction of the mixture into a primary or main air stream for supply to the cylinders of the engine. A first form of the vaporizer uses exhaust gas from the engine to heat the fuel and air, and a second form of the invention uses electrical resistance elements to heat the fuel and air. Both forms of the invention include supplemental vaporized fuel supply devices operable during acceleration and starting.
Claims11
A fuel vaporizer for an internal combustion engine, comprising:
- carburetor means for regulating the supply of air and fuel mixture to the engine, said carburetor means including a tubular housing for flow of a primary air stream to the engine;
- fuel atomizing means for atomizing liquid fuel supplied thereto;
- fuel vaporizing means connected between the fuel atomizing means and the carburetor means to vaporize the atomized fuel and to supply air and vaporized fuel to the primary air stream, said fuel vaporizer means comprising a vaporizer chamber having an inlet end for receiving air and atomized fuel and an outlet end for delivery of air and vaporized fuel to the carburetor means, and heating means operatively associated with the vaporizer chamber to heat the air and atomized fuel flowing therethrough to dry and vaporize the atomized fuel;
- and
- supplemental vaporized fuel supply means connected with the carburetor means to supply vaporized fuel directly to the carburetor means during start up and acceleration of the engine.
