(EN) Engine cooling device
Abrégé
(EN)

Disclosed is a device for cooling an internal combustion engine in which circulation of cooling water is halted until the cooling water reaches a predetermined temperature, wherein decline in the durability of a radiator, which is caused by thermal strain that occurs when circulation of the cooling water is restarted and the cooling water is introduced into the radiator, is suppressed. An internal combustion engine (10) comprises an electric pump (23), a water temperature sensor (92), a radiator (21), and a thermostat (22). The water temperature sensor (92) detects a cooling water temperature (THW). The radiator (21) is capable of circulating the cooling water between the radiator (21) and an engine cooling system (13). If the cooling water temperature (THW) is equal to or greater than a valve opening temperature (TZ), the thermostat (22) opens and the cooling water is introduced into the radiator (21). An electronic control device (91) performs control in such a way that the discharge pressure of the cooling water is increased by the electric pump (23) before the thermostat (22) opens and cooling water is introduced into the radiator (21).
