PURPOSE:To prevent the occurrence of a heat injury by driving a cooling fan based on a timer when a lubricating oil temperature is above a given value at the time of engine stop in the device in which the hot air within an engine room is exhausted by driving the cooling fan at the time of engine stop. CONSTITUTION:In an engine room 26, the radiator fan 27, positioned in the front part of the room 26 and sending air in the front direction, and the bonnet fan 28, positioned on the upper part of the rear side and sending air downward, are arranged, the hot air within the room 26 is exhausted with the fan 27 reversely rotated at the time of engine stop, and also outside air is introduced within the room 26 by the actuation of the fan 28. This enables the cooling within the room 26 to be made. At this time, when a lubricating oil temperature is above a given value at the time of engine stop, each fan 27 and 28 is driven with a timer activated, and also each fan 27 and 28 is made to be continuously driven for a set time of the timer also at the time of re-stop after the restart of an engine. |
