Abstract

An internal combustion steam engine is operated with an alcohol-water fuel mixture vaporized prior to combustion by heated engine coolant that flows through a first heat exchanger. The first heat exchanger or vapor generator uses the waste heat from the engine coolant to heat and vaporize the alcohol-water mixture. A second heat exchanger using exhaust gases heats the combustion air before passage through the intake manifold. Complete vaporization of the alcohol fuel is accomplished to overcome the lower caloric power potential of alcohol as compared to gasoline and to insure complete and regular combustion.
