ABSTRACT:
A vapor-air steam engine is described which operates at high pressure and utilizes a working fluid consisting of a mixture of compressed air, fuel combustion products and steam. In the new cycle described working fluid is provided at constant pressure and temperatures. Combustion air is supplied adiabatically by one or more stages of compression. Fuel is injected at pressure as needed. From 40% to all of compressed air is burned. Water is discretely injected at high pressure to produce steam and thus provide an inert high specific heat diluent required for internal cooling of an internal combustion turbine or other type system. The use of extensive water injection inhibits the formation of pollutants, increases the efficiency and horsepower of an engine, and reduces specific fuel consumption. The new cycle may also be operated open or closed; in the latter case, water may be recouped via condensation for regenerative reuse.
