Abstract (en)
The present invention has a waste heat recovery device (37) that supplies engine waste heat by way of engine coolant; a radiator (18) that dissipates engine waste heat by way of engine coolant; an exhaust gas heat exchanger (33) that supplies engine waste heat from exhaust gas to engine coolant; and a coolant pump (32) that causes engine coolant to circulate. Furthermore, the constitution is such that pressure drop equipment (34) is arranged upstream with respect to a coolant pump suction region (32b); a restrictor is arranged in a communication passage (50) between a coolant pump suction region and a region (20) vented to atmosphere; a location upstream with respect to the pressure drop equipment is made to communicate with the region vented to atmosphere; and the region vented to atmosphere is made capable of being kept in communication with atmosphere.
