(Effects) The present invention accommodates an engine body and a muffler in a soundproofing liquid tank, fills the soundproofing liquid in the soundproofing liquid tank, and places the engine body and muffler in a soundproofing liquid tank. A radiator is immersed in liquid and placed outside the soundproofing liquid tank, the water jacket inside the engine body is connected to this radiator, an electric radiator fan is placed corresponding to the heat dissipation part of the radiator, and the soundproofing liquid tank is immersed in liquid. A temperature sensor that detects the liquid temperature inside the tank is placed on the side wall of the soundproof liquid tank, and the electric radiator fan is driven and controlled based on the liquid temperature detection operation by the temperature sensor. The radiator fan is stopped while the temperature of the liquid in the tank is low, and when the temperature sensor detects that the temperature of the liquid in the tank has risen above a predetermined temperature, the radiator fan is activated and the temperature of the liquid increases. can be controlled within a certain range. Furthermore, since the radiator fan is operated only when necessary, it can contribute to energy saving.
