あった。(Problems to be Solved by the Invention) Cooling water pumped from the water pump 22 increases in temperature as it passes through the engine 11 and the exhaust gas heat exchanger 21, and then passes through the heat storage tank 18 or the radiator 25, where the temperature rises. goes down. At this time, the cooling water is the fluid in the heat storage tank 18 (
Since the water is affected by the temperature of the water 19 or the outside temperature of the radiator 25, the water temperature changes when it returns to the engine 11 again. Therefore, when the engine cooling water level becomes low, there is a problem in that the efficiency of the engine decreases.
