Abstract (en)
When the coolant temperature is greater than or equal to a threshold value while an engine 1 is stopped, a cooling apparatus is driven to cool the engine 1. The threshold value is set as follows. That is, when the crank angle at the completion of stopping of the engine 1 is a crank angle at which a piston 4 of a cylinder (first combustion cylinder) in which a compression stroke takes place for the first time after the subsequent initiation of starting of the engine is at the bottom dead center, the threshold value is set to a coolant temperature (lower limit value) that does not cause pre-ignition in the initial explosion cylinder at the subsequent initiation of starting of the engine. Also, when the crank angle at the completion of stopping of the engine 1 is a crank angle at which the position of the piston 4 in the initial explosion cylinder is closer to the top dead center than the bottom dead center, the closer to the top dead center the position of the piston 4 provided by a crank angle, the higher the threshold value, which is set to a value higher than the lower limit value, becomes.
