A cooling oil passage is formed to circulate engine lubricating oil through the cylinder jacket to cool the cylinder jacket, and the return oil passage from the cylinder jacket of the cooling oil passage is connected to the outlet of the air cooler. A heat exchanger was installed to exchange heat with the cooling water on the side.

The air cooler has two stages, high temperature and low temperature, and a heat exchanger that utilizes waste heat is placed in the middle between them, that is, on the outlet side of the low temperature air cooler. The heat recovered can be used directly for heating living quarters, heating fuel oil, etc.

度レベル（通常100℃以上）に達する。 Since the cylinder jacket 3 is cooled with lubricating oil, it can be used at a temperature level that can be used at normal pressure (in the case of water, the boiling point is 100° C. or lower at atmospheric pressure). The pressurized fresh water supplied from the air cooler inlet B is heated as it passes through the low-temperature air cooler 14, the cooling oil cooler 10, and the high-temperature air cooler 13, and at the outlet A it is heated for living areas, fuel tanks, etc. reach available temperature levels (usually above 100°C).
