ABSTRACT:
The engine has a compressor which compresses air for delivery via a heat exchanger to an expander. The expander receives the compressed air and fuel and, while combustion occurs during a power stroke, the air pressure is reduced to atmosphere and the expander drives a crankshaft. The fuel is injected at a rate to maintain the air temperature at the entry temperature. The exhaust passes through the heat exchanger to heat the incoming flow of compressed air to the expander. Energy may be stored via the crankshaft or used directly.
