Abstract
An internal combustion engine includes a compression cylinder having an air inlet and outlet, a conduit extending from the compression cylinder air outlet, an expansion cylinder of larger diameter than the diameter of said compression cylinder and having an inlet and outlet, and a heat exchanger disposed in the conduit and having a first passageway for flowing compressed air from the compression cylinder outlet to the expansion cylinder inlet, the expansion cylinder outlet being in communication with a second passageway in the heat exchanger for flowing combustion exhaust gases from the expansion cylinder through the heat exchanger. The heat exchanger operates to heat the compressed air before entry into the expansion cylinder and to cool the exhaust gases before entry into an exhaust conduit in communication with the heat exchanger second passageway.
