A description is given of a waste heat recovery system for an internal combustion engine having a mixture of ammonia and water used in the cooling system. The hose and radiator portion of the cooling system is protected from high pressures within the water jacket by a pressure regulator valve. A pump is provided for pumping the coolant from the low pressure system to the high pressure system. Water vapor leaving the water jacket with the ammonia vapor is removed and returned to the water jacket by means of a rectifier. The ammonia vapor is super heated by engine exhaust gases and is then used to drive a turbine. The ammonia gas which has been cooled by expansion in the turbine is used to cool a secondary fluid before the ammonia is returned to the radiator absorber. The secondary fluid cooled by the returning ammonia vapor is used to provide cooling for the rectifier.
