| Abstract | ||
| IC engines are a major source of noise pollution. An engine noise is mainly due to exhaust noise. Suppressing of an engine exhaust noise has been a subject of interest for many years. Mufflers are used to minimize sound transmission caused by exhaust gases. Thus, muffler design becomes more important in noise reduction. The present work compares between three different types of an exhaust muffler for noise attenuation of single cylinder four stroke air-cooled gasoline engine. A set of conclusions achieved about the effect of the mufflers chamber's expansion ratio, chambers length, and wall thickness. Some of them agree with former works | ||
