Internal combustion engine for diverse fuels

A device that operates in conjunction with an internal combustion engine to produce cyclic vaporization of discrete amounts of fuel that are subsequently utilized in the operation of said internal combustion engine comprising in combination, a fuel vaporizer chamber, a vaporizer valve, means to cyclically open said vaporizer valve to replenish said fuel vaporizer chamber with hot gaseous products of combustion generated by said internal combustion engine, means to cyclically introduce into said fuel vaporizer chamber metered amounts of fuel that vaporizes by absorbing heat from said replenished hot gaseous products of combustion, means to close said vaporizer valve such as to temporarily entrap inside said fuel vaporizer chamber said replenished hot gaseous products of combustion and said metered amounts of fuel, means to cyclically open said vaporizer valve to discharge from said fuel vaporizer chamber the resulting mixture of said vaporized fuel and said replenished hot gaseous products of combustion supplying said internal combustion engine in a manner that forms a combustible mixture.

An intermittent internal combustion engine having a combustion chamber and means for supplying a fresh charge of air thereto, the improvements comprising, a fuel vaporizer chamber communicating with said combustion chamber, a vaporizer valve, between said fuel vaporizer chamber and said combustion chamber, means to cyclically open said vaporizer valve during the compression stroke to vent its content into said combustion chamber to form a combustible mixture, means to cyclically close said vaporizer valve during the expansion stroke of the engine to entrap hot product of combustion within said fuel vaporizer chamber, a fuel injector discharging into said fuel vaporizer chamber, means to cyclically supply said fuel injector with a metered amount of liquid or slurry fuel while combustion products are entrapped whereby the fuel is vaporized inside said fuel vaporizer chamber because it absorbs heat by direct mixing with the entrapped hot products of combustion.
