Title:
COOLING DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JPS6385215
Kind Code:
A
Abstract:
PURPOSE:To elevate clean water temperature so as to seek effective use of exhaust heat by pressurizing the whole cooling system with pressure air after enclosing, in a device where a cylinder, an exhaust valve and an air cooler, etc. are cooled by clean water. CONSTITUTION:In the cooling system of a Diesel engine 1, the cooling water discharged from an exit main pipe 3 is cooled with a cooler 5 and then circulated into inside of the engine 1 through an entrance main pipe 2 after being elevated in pressure with a clean water pump 4 and hereby the engine 1 is cooled. In this case, the whole cooling system is so constituted that it may be pressured by adding pressuring air into a pressuring tank 6 through an air pipe 8. Hereby the maximum temperature of the cooling water inside the engine becomes possible to elevate up to about 120 deg.C-164 deg.C and the exhaust heat from the engine can be used effectively as heat source for various kinds of heaters such as lubricant heater, fuel heater and others which were not available up to now due to the low water temperature.
