摘要： PROBLEM TO BE SOLVED: To inhibit the degradation of a battery during the dead soak of an engine and improve restartability at high temperatures and idle rotation stability by efficiently cooling the engine.SOLUTION: A cooling device cools an engine body 2 by circulating cooling water between an engine body 2 and a radiator 3 using an electric motor 1 and by supplying cooling wind to the radiator 3 using an electric fan 4. A control unit 30 controls the operational states of the electric motor 1 and the electric fan 4 based on a cooling water temperature THW detected by a water temperature sensor 21, an outdoor air temperature THA detected by an outdoor air temperature sensor 22 and a battery voltage GBA during the dead soak after the engine is stopped. Specifically, the control unit 30 controls the electric motor 1 and the electric fan 4 when determining that the engine is at a high temperature based on the cooling water temperature THW and the outdoor air temperature THA at the stop of the engine.
