ABSTRACT:
A heat engine power system includes a fluid fuel heat engine designed to determined performance characteristics for military vehicles, and a cooling subsystem which has enough capacity to carry away the rejected engine heat. When the exigencies of parts support require replacement of the original engine by a more powerful one which at high ambient temperatures and wide-open throttle would overload the cooling subsystem, the speed controls are such that either of two heat sensors closes an electric circuit to a solenoid which is energized to move the throttle to a given position to restrict fuel flow to an amount which limits engine output so that the rejected heat is within the capacity of the cooling subsystem, thus avoiding overheating and failure, and keeping the military equipment in service without permanently sacrificing total available horsepower.
