ジン冷却装置。 A first coolant circulation circuit that circulates between the first heat exchanger and the cylinder head, a second coolant circulation circuit that circulates between the second heat exchanger and the cylinder block, and this second coolant circulation circuit. A third heat exchanger exchanges heat between the first coolant bypassed from the circuit and air introduced from the outside; The fourth part where heat is exchanged with the air that has passed through the exchanger.
When the heat exchanger and the second cooling liquid do not exceed the first set temperature, the first cooling liquid is bypassed to the third heat exchanger, and the second cooling liquid is bypassed to the fourth heat exchanger, and the second cooling liquid is bypassed to the fourth heat exchanger. The second set temperature of the liquid is higher than the first set temperature.
An engine cooling device comprising: control means for bypassing the second coolant again to the fourth heat exchanger when the temperature exceeds a set temperature.
