DESIGN AND ANALYSIS OF AUTOMOTIVE MUFFLER

Abstract

Noise pollution is a major issue in today's culture, thus soundproofing is an absolute must if you want to minimize the level of noise. The muffler is an important component of the vehicle's exhaust system because it reduces the noise produced by the combustion products as they pass through the system. Maintaining a minimum pressure drop while limiting noise is a difficult task. A new muffler is created and built using software that takes into account a range of elements. The standard exhaust fitted on the Maruti-Suzuki WagonR is first considered, and then the replacement muffler is examined using numerical codes. It is simple to develop the ideal configuration that reduces back pressure, pressure drop, and noise by adjusting the design parameters in light of the study. The noise blocking performance, pressure lowering, and lifespan of the recommended built muffler can be compared to those of a standard muffler. The intensity of the noise was measured with a Sound Level Meter (SLM), and the pressure drop was monitored with a water manometer tube.
