초록

The invention is a reciprocating bottom cycle engine whose principal is heat addition by recovering heat from a top cycle engine through a counterflow heat exchange recuperator. The engine operation approximates the ideal bottom cycle for recovering heat from a top cycle: isothermal compression, recuperative heating, and constant entropy expansion. Such a cycle is capable of utilizing all the work potential between the hot top cycle exhaust and cool ambient temperature. Practical engines operating on this cycle do not achieve the ideal performance but ar...
