Abstract:
A waste heat recovery system includes an evaporator that evaporates a coolant in a liquid phase by using waste heat from an internal combustion engine, a turbine that rotates by receiving the coolant in a gas phase having passed through the evaporator, a condenser that condenses the coolant in the gas phase having passed through the turbine into the coolant in the liquid phase, and a pump that supplies the coolant in the liquid phase fed from the condenser to the evaporator. The waste heat recovery system further includes a coupling mechanism that constantly couples a rotating shaft of the turbine to a crankshaft of the internal combustion engine, and the crankshaft is directly coupled to a vehicle transmission.

Claim (Index 2):
The waste heat recovery system for an internal combustion engine according to  claim 1 , further comprising:\n a turbine control valve arranged between the turbine and the evaporator; a vacuum pump that feeds the coolant in the gas phase having passed through the turbine to the outside; and a controller that controls the turbine control valve and the vacuum pump, wherein, in a period when the turbine control valve is closed, the controller is configured to activate the vacuum pump to set an outlet pressure of the turbine to be lower than a predetermined negative pressure value.
