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