An engine with positive displacement piston chambers, an external combustion chamber from which combustion gases pass through suitable valving to piston chambers, an air compressor, a heat exchanger where exhaust gases from the piston chambers preheat compressed air which then flows to the combustion chamber, and an accumulator for storing unneeded compressed air from the compressor. The system has the capability of regenerative braking, i.e., slowing the engine by employing it as a compressor to compress air which is passed to the accumulator.
