An engine cooling system decreases vehicle weight caused by employing a Rankine cycle, makes it possible to improve the performance of the Rankine cycle, and includes a coolant that circulates through a cooling pump, an evaporator, an expander, and in a condenser in this order; an engine main body in which a turbocharger is arranged in an intake passage; and a radiator through which cooling water for the engine main body circulates. A sub-radiator is installed parallel to the radiator; air that is compressed by the turbocharger is used as a heating source for the evaporator; and outlet-side cooling water of the sub-radiator is used as a cooling source for the condenser. |

1. An engine cooling system comprising:
a Rankine cycle configured such that a coolant circulates through a cooling pump, an evaporator, an expander, and a condenser in this order; an engine main body in which a supercharger is arranged in an intake passage; a radiator through which cooling water for the engine main body circulates; and a sub-radiator installed parallel to the radiator, wherein air compressed by the supercharger is used as a heating source for the evaporator, and wherein outlet-side cooling water of the sub-radiator is used as a cooling source for the condenser. |
