Patent ID: 11053893

Abstract:
A cooling system CS according to one aspect of the present invention is provided with: a first cooling circuit C1 which is provided with a first cooling means 54 and in which cooling water can circulate; a second cooling circuit C2 which is provided with a second cooling means 64 and in which cooling water for cooling an engine body 12 can circulate; and an EGR cooler 46 configured to cool an EGR gas. The EGR cooler 46 is provided with: a first EGR cooler 52 installed in the first cooling circuit C1; and a second EGR cooler 62 installed in the second cooling circuit C2. Furthermore, in order to suppress the generation of condensed water due to condensation of moisture in an exhaust gas during the cooling of the EGR cooler 46, the cooling system CS is provided with a valve 80 configured to control the amount of the cooling water that flows from the second cooling circuit C2 to the first cooling circuit C1.
