In order to improve the cooling performance of an engine cooling system, the system is provided with: a Rankine cycle device (50) in which an evaporator (52), an expander (53), a condenser (54), and a compressor (55) are arranged in order in a circulating flow path (51); a flow path (31) inside a cylinder block; a main radiator (32); a sub-radiator (36); a main flow path (33) that passes through the main radiator (32); a heating flow path (34) that passes through the evaporator (52); a sub-flow path (37) that passes through the sub-radiator (36); and a cooling flow path (39) that branches off from the sub-flow path (37) and passes through the condenser (54). |
