STATIONARY ENGINE COOLANT CIRCUIT
First Claim
1. A stationary engine coolant circuit having a waste heat recovery device that supplies engine waste heat by way of engine coolant;
- a radiator that dissipates engine waste heat by way of engine coolant;
an exhaust gas heat exchanger that supplies engine waste heat from exhaust gas to engine coolant; and
a coolant pump that causes engine coolant to circulate,the stationary engine coolant circuit being characterized in that it is constituted such that pressure drop equipment is arranged upstream with respect to a coolant pump suction region, and two of the coolant tanks are provided;
a vent pipe capable of being kept in communication with atmosphere being provided at one of the tanks; and
further, an air pocket region at the one tank being made to communicate with an air pocket region at the other tank;
a location upstream with respect to the pressure drop equipment being made to communicate with a watersealed region at the other tank; and
a restrictor being arranged in a coupling passage between the location upstream with respect to the pressure drop equipment and the watersealed region.

Abstract
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.
