Disclosed is a cycle piston engine power system in which a compression ignition or spark ignition reciprocating piston engine is made non-emissive via a semi-closed cycle, in a manner which produces saleable CO2 product at pressure. The cycle piston engine power system can includes, among other elements, a piston engine for generating power and exhaust gas; a water cooling and separation unit which receives the exhaust gas and cools and removes water from the exhaust gas to create CO2 gas supply; a mixing pressure vessel which receives at least a portion of the CO2 gas supply from the water cooling and separation unit and mixes the CO2 gas supply with oxygen to create a working fluid to be provided to the piston engine; and an oxygen generator for providing oxygen to the mixing pressure vessel.
