FIELD: engines and pumps.
SUBSTANCE: ammoniac low-temperature efficient engine and method for its operation, consisting in the fact that refrigerator for ammoniac turbine is ammonia-ammonia heat exchanger with temperature of ammonia boiling at T'1=250°K (-23°C). Heater for ammonia turbine is condensation and NH3 cooling heat on the one side in ammoniac heat pump, and on the other side - heat from combustion of hydrocarbon fuel in boiler.
EFFECT: increased efficiency of heat engine.
