A first cooling water circuit 4 for cooling the cylinder block 3 and a second cooling water circuit 5 for cooling the cylinder block 3 are formed separately and independently, each having separate radiators 6, 8 and cooling water pumps 10, 11. In the engine cooling system, the impeller 12 of the first cooling water pump 10 arranged in the first cooling water circuit 4 and the impeller 12 of the second cooling water pump 11 arranged in the second cooling water circuit 5 are arranged. The impeller 13 of the second cooling water pump 11 is rotated together by one rotating shaft 14 driven by the engine 1.
The impeller 13 is composed of an end surface 26 in which an insertion hole 28 for the blade 17 of the impeller 13 is opened, and a cylindrical wall body 27 along the outer periphery of the impeller 13. An impeller cover 16 that can change the effective width of the blades 17 of the wheel 13 in the direction of the rotation axis 14 is arranged, and the impeller cover 16 is slid by an actuator 24 that operates according to the operating state of the engine 1. and the second cooling water circuit 5
An engine cooling device that controls the flow rate of cooling water of the engine 1 in accordance with the operating state of the engine 1.
