Abstract

PURPOSE: To provide an engine cooling system, in which temperature of cooling water is detected at the inlet side or outlet side of engine to achieve on-off control of a valve disposed in a cooling water passage circulated through the engine and cooling tank, whereby it is enabled to supply cooling water of substantially constant temperature to the engine and thus occurrence of distortions in the engine can be prevented.
CONSTITUTION: Cooling water is circulated from cooling tank 1 to cooling pipe 9 of engine 8. With detection of temperature rise of cooling water at a portion near outlet 11, outlet valve 13 is opened and cooling water is returned to cooling tank 1 via connecting pipe 12. While cooling water is circulated as above, temperature of the cooling water is gradually raised. When temperature of cooling water in tank 1 is raised and resultantly thermostat 7 is actuated, return valve 16 is closed and exhaust valve 15 is opened, whereby cooling water is discharged to the outside. Then, water supply valve 4 is opened and cooling water is supplemented from water tap 2, so that temperature of cooling water is lowered. When the temperature of cooling water is lowered to a predetermined level, exhaust valve 15 is closed and return valve 16 is opened, whereby temperature of the cooling water can be kept substantially constant
