A Review on Muffler Design for Exhaust Noise Attenuation

Muffler Design for Automotive Exhaust Noise Attenuation - A Review

In these review paper different types of mufflers and design of exhaust system belonging engine has been studied. The object of this study is decide muffler design which one reduces a large amount of noise level and back pressure of engine. In designing, there is different parameter which has to taken in to the consideration. These parameters affect the muffler efficiency.

Study on Acoustic and Fluid Characteristics of Exhaust Muffler

Engine noise is mainly from exhaust noise. Without adding muffler, at a certain speed, the noise up to 100 decibels. Reduce engine exhaust noise, and to high-temperature exhaust gas can be safely and effectively. Muffler as part of exhaust pipe, should ensure that the exhaust flow, resistance and sufficient strength. This research takes an exhaust silencer as a study object, and a muffler sound...

Numerical simulation of exhaust muffler An homogenized finite element method

RÉSUMÉ. L’objectif de ce travail est de calculer l’atténuation acoustique dans un pot d’échappement contenant des tubes perforés. On se place en régime harmonique et en absence d’écoulement, ceci nous amène à résoudre l’équation de Helmholtz. L’utilisation de techniques d’homogénéisation, nous permettent de prendre en compte la présence des tubes perforés à l’aide de condition d’impédance équiv...

Modeling and simulation of the acoustic behavior of a muffler in a passenger car exhaust system

Muffler is one of the main components of an automotive exhaust system, which reduces the noise of the exhaust system. In this paper, modeling and simulation of the acoustic behavior of a muffler is presented with the aid of  an engineering software. For this purpose, firstly, an analytical model is presented to evaluate the sound transmission loss in cylindrical shells based on Sander's theory....
