Abstract
An engine includes two or more serially connected air compressors coupled via a crankshaft to an expander piston and cylinder combination. An intercooler device is placed between the air compressors. Compressed air from the compressors flows through a heat exchanger where it is heated by the expander exhaust gas prior to its introduction into the expander cylinder by way of an inlet valve. Fuel is mixed with the compressed air near the inlet valve in an amount suitable to allow for combustion. An auxiliary compressor allows for the selective introduction of additional compressed air into the heat exchanger
