風の出入りが必要なため、エンジンＣを密閉できないだ
けでなく、消音のための大きなスペースが必要となって

体の表面から出る機械騒音
ｉｉｉ 冷却ファン及び放熱機から出る騒音これら３
つの主要な騒音源を遮断して外部に騒音が出ないように
するためには次の手段が有効である。i Engine exhaust noise and engine compressor intake noise ii Mechanical noise emitted from the surfaces of the engine body, generator body, and compressor body iii Noise emitted from the cooling fan and radiator These three
The following measures are effective in blocking the two main noise sources and preventing noise from emitting outside.
ｉ エンジン吸排気音を極力低減するために消音器を改
良する。i. Improve the muffler to reduce engine intake and exhaust noise as much as possible.
そしてより消音効果を上げるためにはより大きな消音器

ら充分な大きさのものを採用できない。That is, the muffler d for exhaust gas cannot be of sufficient size due to space constraints.
また、大量の冷却風を必要とするためエンジン等を密閉
できないばかりでなく、冷却ファンａの音も充分な低減
効果を得られすそのコストも高価となる。Further, since a large amount of cooling air is required, not only the engine etc. cannot be hermetically sealed, but also the sound of the cooling fan a cannot be sufficiently reduced, but its cost is also high.
