COOLING DEVICE FOR INTERNAL COMBUSTION ENGINE

WIPO Patent Application WO/2011/148464

A1

A cooling device for an internal combustion engine, configured so that coolant circulation is stopped until the temperature of the coolant reaches a predetermined temperature, wherein thermal shock to the internal combustion engine, which is likely to occur when the stop of the coolant circulation is cancelled, is reduced. An internal combustion engine (10) is provided with: a main passage (24) and a sub-passage (27) which form the engine cooling system; a coolant temperature sensor (92) which detects a first temperature which is the temperature of the coolant within the internal combustion engine (10); and an electric pump (23). A control device (91) controls the electric pump (23) so that the coolant circulation is stopped when the first temperature is lower than a predetermined temperature. Also, the control device (91) sets the discharge amount of the coolant which is discharged from the electric pump (23) when the stop of the coolant circulation is cancelled, the setting being performed on the basis of the temperature of the coolant within the sub-passage (27) when the coolant circulation is being stopped.
