Noise reducing enclosure for water cooled engine - has enclosing housing and indirect cooling system for engine circulating coolant

摘要

The liquid cooled internal combustion engine has noise reducing devices. This arrangement not only reduces explosion noises but also those due to mechanical moving parts. The complete engine (1), together with the exhaust (9) is arranged for wet operation by an enclosing housing (2). A cooling pipe system (6) is used for indirect cooling of the engine cooling liquid circulating within the housing. A rubber bellows (7) is used for generating necessary circulation of the cooling liquid within the housing (2).
