Design Analysis and Pressure Loss Optimization of Automobile Muffler

Abstract

Noise from exhaust system of automobile is the major concern and cause of noise pollution. That is why it is a major concern and important area of research and development. Muffler is an important part of the engine which is used to minimize sound from exhaust, backpressure that affects fuel efficiency, noise as well as emission. The proposed design of muffler is chosen through so much of iteration on different designs. This paper mainly concerns to establish the relation between the pressure loss and the exhaust gas inlet velocity. So, the backpressure must be kept minimum. It also deals with the design methodology of muffler which will be an improvement to the existing design of muffler, improvement in terms of design, pressure loss, and noise level. It also focuses on modern cad tools and simulation tools which provide maximum advantage for optimizing the design in short time and for better result.
