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.

An engine comprising: a compressor configured for compressing ambient air into compressed air having a pressure greater than or equal to six atmospheres, and having an elevated temperature; and a combustion chamber connected to the compressor, wherein the combustion chamber is configured to duct a progressive flow of compressed air from the compressor; and fuel injection means for injecting fuel into the combustion chamber; and liquid injection means for injecting liquid into the combustion chamber; and a combustion controller for independently controlling the compressed air, the fuel injection means, and liquid injection means so as to combust the injected fuel and at least a portion of the compressed air and to transform the injected liquid into a vapor wherein a working fluid consisting of a mixture of compressed air, fuel combustion products and vapor is generated in the combustion chamber during combustion at a predetermined combustion temperature, substantially all of the cooling of the temperature of the working fluid from a combustion temperature to an exit temperature being provided by the latent heat of vaporization when the injected liquid is converted to vapor upon injection into the combustion chamber; wherein the injected liquid is seawater, engine further including desalination means to remove salt from the seawater and collect such salt from the combustion chamber and a work engine coupled to and supplied with working fluid at the exit temperature from the combustion chamber.
