By the way, if the engine is a water-cooled engine, the cooling water jacket can be used as a heat exchanger for heating hot water. However, conventional water-cooled engines generally have a cylinder and a cylinder head that are separate bodies, and have a structure in which they are tightened and fixed with bolts with a gasket interposed between them. When such an engine is used as a water heater engine, the water in the cooling jacket recovers heat to heat the water for hot water supply, making it difficult for the water temperature to rise.As a result, the cylinder and cylinder head thermally expand, and the gasket increases its sealing force. It will take a considerable amount of time to strengthen it.

The engine 1 described above has at least a cooling jacket 1a.
Since the cylinder 21 and cylinder head 20 forming the engine are integrally cast, there is no need for a sealing gasket as in conventional separate engines. Therefore, even if the cylinder 21 or the cylinder head 20 is at a low temperature, there is no problem of blow-through from the gasket or mixing of water and oil.

Furthermore, when the cylinder 21 and the cylinder head 20 are integrally cast, a right-angled portion will be formed between the intake and exhaust passage and the baking chamber due to casting. But “two wages?” A

Since the speed is as low as 2,500 rpm and N degrees, a large flow rate is not required, and therefore the perpendicular flow path shown in -1 does not pose a problem. For the same reason, there is no problem even if the mixer 25 is integrally provided in the intake passage 23 as in the embodiment, and it is advantageous to make the device more compact. In addition, with the monolithic casting structure, there is a problem that it becomes difficult to remove tar deposits that accumulate in the combustion chamber.
! As in the case of an engine that uses household gas as fuel, there is almost no tar generation, so this is not a problem.

Furthermore, if the cylinder 21 is placed horizontally as in the embodiment, and the oil reservoir 36 is configured to extend to the bottom of the cylinder, the flat area of the oil reservoir can be increased, and the oil amount can be increased while making the oil depth relatively shallow. Therefore, oil can be used effectively and a long-term maintenance-free engine is possible.
