ABSTRACT:
A modified Ericsson cycle engine, the operating cycle of which involves sequential modes of substantially adiabatic compression, constant pressure heat addition, constant temperature expansion, heat rejection at constant volume and heat rejection at constant pressure. A preferred engine embodiment includes at least one compression cylinder discharging compressed heated air through an exhaust heat recuperator to a constant pressure heat make-up combustor wherein fuel is discharged into the air stream and ignited, at least one expander cylinder receiving the fuel-air mixture from the combustor for expansion therein, additional fuel being supplied to the gases within the expander cylinder whereby expansion will take place within the expander cylinder at constant temperature, after which the mixture is then discharged through the exhaust passages in the exhaust heat recuperator through the atmosphere.
