Further, if the muffler 9 is arranged above the engine 1 as in the above embodiment, the exhaust pipe 8 can be shortened, and the amount of heat dissipated up to the muffler 9 can be reduced. Therefore, it is possible to improve the heat absorption efficiency in the heat exchanger 10. Furthermore, since the heat radiation from the exhaust pipe 8 is reduced, thermal deterioration of the rubber toothed belt 21 can be suppressed.

0 to make effective use of exhaust heat, but from the viewpoint of measures against exhaust gases such as NOx, this configuration is suitable when using the engine 1 that performs lean gas combustion as in the embodiment. It can be effective. This is because in an engine that uses a catalyst for exhaust gas treatment, if the muffler in which the catalyst is inserted is cooled by a water jacket, the reaction will not be promoted and harmful components will not be removed. The difference in effectiveness between lean combustion and catalytic treatment is particularly noticeable in the early stages of engine startup when the engine temperature is low. The example is for household gas, but even in the case of a gasoline engine, a muffler equipped with a water jacket can be effectively utilized in the same way if the engine is a lean combustion engine that uses a lean mixture with a large excess air ratio. .
