Abstract (en)

A flow control mechanism (300) is disposed downstream of an exhaust heat recovery device (150) on a cooling water circuit (500b) between the exhaust heat recovery device (150) and a water pump (120). The flow control mechanism (300) controls a flow rate of cooling water in accordance with a cooling water temperature around the flow control mechanism (300). When the cooling water temperature is low, the flow control mechanism (300) does not limit the flow rate of the cooling water to perform exhaust heat recovery. When the cooling water temperature is increased, the flow control mechanism (300) limits the flow rate of the cooling water to stop the exhaust heat recovery. Further, the flow control mechanism (300) again increases the flow rate of the cooling water when the cooling water temperature is increased to around the boiling point of the cooling water while the exhaust heat recovery is stopped.
