Abstract:After theoretical analysis of it. the author puts forward spherical expansion chamber silencer element.It has an advantage of a larger transmission loss over the cylinder expansion chamber.The spherical expansion chamber is used in the newly-designed exhaust silencer for S195 diesel engine, showing that it is featured by a larger transmission loss and lower specific fuel consumption than No.3 silencer.
Keywords:exhaust noise  noise silencer  reactive mufflers
