摘要： PURPOSE:To prevent the thermal deterioration after the engine stop by operating a coolant feeding pump when the temperature difference between the coolant in a water jacket and a condenser lower tank is over a prescribed value, while operating a cooling fan when the temperature difference is below a prescribed value. CONSTITUTION:The coolant vapor generated in a water jacket 2 is introduced into a condenser 3, and after cooled by a cooling fan 16, the liquid phase coolant is stored into a lower tank 15. The coolant in the lower tank 15 is returned into the water jacket 2 through the first coolant recirculation passage 23, reservoir tank 21, the second coolant passage 24, and a coolant feeding pump 4. The water jacket 2 and the lower tank 15 are equipped with the first and the second temperature sensors 12 and 17, respectively, and when each detection value of the both sensors 12 and 17 after the engine stop is over a prescribed value, the coolant feeding pump is driven, and when the detection value is below a prescribed value, the cooling fan 16 is driven by a controller 27.

摘要： PURPOSE:To contrive to improve cooling performance by controlling a motor for a cooling fan on the basis of inlet cooling water temperature of a cylinder head and various informations on an engine operation so as to avoid overshoot of cooling water inlet temperature at the time of transient operation. CONSTITUTION:An engine main body 1 has a cylinder head 1a and a cylinder liner 1b and each water jacket 2, 3 respectively provided in these both 1a, 1b is respectively cooled by separate cooling systems A, B. Then the cooling system A has a radiator 4 for cooling the cylinder head 1a, a fan for the radiator 4 and a pump 6 for circulating cooling water and these are connected by cooling pipe lines 7-9. In this case, a water temperature sensor 10 is provided, at the inlet side of the radiator 4, on the line 7. And a motor 5a for the fan 5 is controlled, on the basis of a signal from the water temperature sensor 10 and various information on engine operating conditions, through and electronic control circuit 11.
