ABSTRACT:
A waste heat recovery system of an engine has a cooling water circuit and a Rankine cycle. Cooling water is circulated between the engine and a radiator in the cooling water circuit. The Rankine cycle has a heater and an expansion device. The heater performs heat exchange between the cooling water heated by the engine and an operation fluid so as to heat the operation fluid in the Rankine cycle. The expansion device expands the heated operation fluid, so as to generate driving power. The heater is arranged in a bypass circuit so as to be in parallel with the radiator with respect to the cooling water flow. Thus, waste heat of the cooling water heated by the engine can be effectively recovered without reducing a cooling capacity of the radiator.
