Abstract

Acoustic design of EXHAUST system for Internal Combustion Engines normally has been based on trial and error, such that even most muffler producers are mainly dependent on practical experience of their designers. The primary reason for this is the complex process of EXHAUST system acoustic analysis design. The basic design goals are: I) Optimum and compact EXHAUST system geometry II) Acceptable reduction of EXHAUST noise III) Enforcement minimum back pressure with proper acoustic performance. The primary object of present article is to employ the linear acoustic filter theory based on the method of transmission loss for optimum design of reactive acoustic SILENCERs in the EXHAUST system of internal combustion engine. The numerical results examine the effect of internal geometry of various reactive elements on acoustic performance of the EXHAUST system.
