どする自動車用内燃機関の冷却装置。In a cooling system for a liquid-cooled automobile internal combustion engine equipped with a radiator, a temperature sensing device is installed in the middle of the engine's coolant passage to sense the temperature of the coolant flowing through the passage! At the same time, the above-mentioned temperature-sensing device is installed in the coolant passage downstream of the temperature-sensing device and upstream of the water pump. In response to this, when the coolant temperature is below the first set temperature, the above passage is shut off in any operating range of the engine, and when it exceeds the first set temperature and is below the second set temperature, it is shut off in the low load range or during idling. Is the above only true when there is no load? 1. A cooling device for an internal combustion engine for an automobile, characterized in that a control valve is installed which blocks the passageway and further communicates the passageway even in any operating range where the temperature exceeds a second set temperature.
