ABSTRACT:
An engine has preferably coupled together a reciprocating air compressor discharging through a heat exchanger into a reciprocating cylinder piston combination, the flow into the piston cylinder combination being controlled by a cam-actuated inlet valve which is maintained open for a substantial fraction of the out-stroke of the combustion piston. There is also an exhaust valve from the combustion chamber which releases exhaust gas to the heat exchanger for transfer of thermal energy to the incoming compressed air. A fuel injector supplies fuel to the compressed air entering through the inlet valve into the combustion chamber over a large part of the out-stroke of the power piston.
