Why use a water-injected “wet” exhaust system?
For a products relating to this article please follow this Link The following factors are of great importance: • Exhaust gas temperatures can reach very high levels. A diesel engine can easily produce an exhaust gas temperature of 600° C or more. • The speed with which sound can be transmitted through air is dependent on the temperature of the air. This applies to exhaust gases as well. The higher the exhaust temperature, the higher the speed of sound through the gas. • The sound level, i.e. the relative volume of sound as experienced by the human ear, is in turn dependent on the speed of sound. As the speed of sound transmission reduces, so the sound level will reduce proportionally. In the past, many boats used a “dry” exhaust system, in which the exhaust gases were transported to outside the hull without any form of cooling. The resultant hot exhaust pipe had to be thoroughly insulated, but even so, it produced a tremendous amount of noise. However, reduction of exhaust gas temperat
