Power system with internal combustion engine

A power system comprising

• a variable volume combustion chamber;
• a controlled exhaust port from the combustion chamber without air intake;
• a fuel injector system including at least one fuel injector directed to the combustion chamber;
• a source of fuel constructed and arranged to charge the fuel injector system with fuel;
• an oxygen injector system including at least one oxygen injector directed to the combustion chamber;
• a source of pressurized oxygen constructed and arranged to charge the oxygen injector system with oxygen, the source of pressurized oxygen including an oxygen separator constructed and arranged to separate oxygen from air and an air intake to the oxygen separator, the at least one fuel injector and the at least one oxygen injector being the sources of a cumulative stoichiometric or leaner combustible charge to the variable volume combustion chamber, the fuel injector system and the oxygen injector system each providing multiple injection pulses into the combustion chamber with completion of the stoichiometric or leaner charge at or after maximum crank leverage, the variable volume combustion chamber including a two-stroke cycle, injection timing of the fuel injector system and oxygen injector system being initiated at or after 12° after TDC of the variable volume combustion chamber.
