As a result, the engine cooling water is circulated to the radiator 3 and the controller 20 closes the on-off valve 7 and operates the electromagnetic pump 10, so that the engine cooling water flows as indicated by the arrow A. Here, since the on-off valve 7 is closed, the engine cooling water does not flow to the heat exchanger 6, and most of the engine cooling water passes through the heat accumulator 9. As a result, the temperature of the engine cooling water that has risen during operation of the engine is reduced, and the temperature of the engine room is also reduced. As a result, at the time of restart, the evaporation of fuel due to the high temperature of the engine cooling water and the engine room is prevented, and the engine can be restarted smoothly.
