An internal combustion engine power cycle wherein a combustion chamber is fitted with an inlet valve, an outlet valve, and movable piston coupled to perform work, includes an generator to form a stream of greater than about 95% molecular oxygen from atmospheric air and a nitrogen waste gas stream; a source of fuel; and a source of liquid water. The power cycle includes admission of the molecular oxygen into the chamber, injection of the fuel into the chamber with combustion, and injection of atomized water into the chamber for generation of steam.

1. A power cycle unit, which comprises: (a) an oxygen generator that generates a stream of greater than about 95% molecular oxygen from atmospheric air and a nitrogen waste gas stream; and(b) a combustion chamber fitted with: (i) an oxygen inlet valve through which said generated molecular oxygen is fed to said chamber,(ii) a fuel inlet valve through which a combustible fuel is injected into said chamber with combustion ensuing in said chamber,(iii) an outlet valve through which a combustion exhaust is removed from said chamber,(iv) a movable piston coupled to perform work, and(v) a water injector that injects atomized liquid water into said chamber for generating in situ steam to further drive said piston. 2. The power cycle unit of claim 1, which additionally comprises a water condenser which is fed with said combustion exhaust from said chamber to recover liquid water to pass to said water injector. 3. The power cycle unit of claim 2, which additionally comprises an exhaust condenser which is fed with said combustion exhaust to recover a cooled exhaust gas flow for admission into said chamber. 4. The power cycle unit of claim 1, which additionally comprises an exhaust condenser which is fed with said combustion exhaust to recover a cooled exhaust gas flow for admission into said chamber. 5. The power cycle unit of claim 1, wherein said oxygen generator comprises a ceramic oxygen generator. 6. An internal combustion engine having a combustion chamber, an oxygen generator that forms a stream of greater than about 95% molecular oxygen from atmospheric air and a nitrogen waste gas stream, a source of fuel, and a source of liquid water, the improvement which comprises said combustion chamber fitted with: (a) an oxygen valve;(b) a fuel valve;(c) an ignition source inside the combustion chamber that ignites fuel from said source of fuel and oxygen;(d) a water valve; and(e) an exhaust valve; and(f) a control system for controlling the combustion chamber such that: (1) substantially pure oxygen from said oxygen generator is allowed to enter the combustion chamber during an intake stroke, said oxygen valve closing near the end of the intake stroke to trap oxygen in the combustion chamber,(2) fuel from said source of fuel is allowed to start entering the combustion chamber when the piston is near top dead center, said fuel continuing to flow until enough has entered the combustion chamber to provide the power needed,(3) ignition timing of said ignition source is variable depending on operating conditions from slightly after the fuel starts to enter the combustion chamber to a short time after the piston passes top dead center,(4) liquid water from said source of liquid water is allowed to start entering the combustion chamber slightly after the ignition source starts the combustion of the fuel and oxygen and continues until after combustion is complete, the amount of liquid water entering the combustion chamber is variable depending on operating conditions, wherein fuel and water injection may occur simultaneously for some portion of the stroke, and(6) exhaust gases are allowed to exit the combustion chamber starting as the piston approaches bottom dead center. 7. The internal combustion engine of claim 6, wherein exhaust gases from said chamber is passed through a condenser to recover liquid water for use as said water source. 8. The internal combustion engine of claim 7, wherein a cooled exhaust gas flow is recovered from said condenser for passing into said chamber along with said molecular oxygen. 9. The internal combustion engine of claim 6, wherein a cooled exhaust gas flow is recovered from a condenser for passing into said chamber along with said molecular oxygen. 10. The internal combustion engine of claim 6, wherein said generator comprises a ceramic oxygen generator. 11. An internal combustion engine having a combustion chamber, an oxygen generator that forms a stream of greater than about 95% molecular oxygen from atmospheric air and a nitrogen waste gas stream, a source of fuel, and a source of liquid water, the improvement which comprises said combustion chamber fitted with: (a) an oxygen valve;(b) a fuel valve;(c) an ignition source inside the combustion chamber that ignites the fuel and oxygen;(d) a water valve(e) an exhaust valve; and(f) a control system for controlling the combustion chamber such that: (1) substantially pure oxygen from said oxygen generator is allowed to enter the combustion chamber during the last part of an exhaust stroke after the exhaust valve closes, said oxygen valve closing near the end of the exhaust stroke to trap the oxygen in the combustion chamber,(2) fuel from said source of fuel is allowed to start entering the combustion chamber when the piston is near top dead center just after the exhaust stroke, said fuel continuing to flow until enough has entered the combustion chamber to provide the power needed,(3) ignition timing of said ignition source is variable depending on operating conditions from slightly after the fuel starts to enter the combustion chamber to a short time after the piston passes top dead center,(4) liquid water from said source of liquid water is allowed to start entering the combustion chamber slightly after the ignition source starts the combustion of the fuel and oxygen and continues until after combustion is complete, the amount of water entering the combustion chamber is variable depending on operating conditions, wherein fuel and water injection may occur simultaneously for some portion of the stroke, and(5) exhaust gases are allowed to exit the combustion chamber as the piston approaches bottom dead center, and the exhaust valve will close prior to the piston reaching top dead center. 12. The internal combustion engine of claim 11, wherein the exhaust gases from said chamber is passed through a condenser to recover liquid water for use as said water source. 13. The internal combustion engine of claim 12, wherein a cooled exhaust gas flow is recovered from said condenser for passing into said chamber along with said molecular oxygen. 14. The internal combustion engine of claim 11, wherein a cooled exhaust gas flow is recovered from a condenser for passing into said chamber along with said molecular oxygen. 15. The internal combustion engine of claim 11, wherein said generator comprises a ceramic oxygen generator.
