とを特徴とする沸騰冷却式エンジン。 Cooling fluid is supplied to the cooling jacket of the engine by a water pump, and cooling is performed using the latent heat of vaporization resulting from evaporation of the cooling fluid, and the boiling fluid has an overflow passage that communicates the upper part of the cooling jacket with the upstream side of the water pump. In the cooling type engine, pump drive control means for driving the water pump when the temperature detected by the temperature detection means for detecting the temperature of steam in the cooling jacket exceeds a set temperature, and supplying cooled liquid to the cooling jacket. an on-off valve interposed in the coolant passage downstream of the water pump; a bypass passage that bypasses the on-off valve and has a passage cross section smaller than the coolant passage cross section;
A boiling-cooled engine, characterized in that it is provided with on-off valve control means for opening the on-off valve with a delay from the start of driving of the water pump.
