Abstract:

The muffler is a very important and an indispensable part of an automobile exhaust system. The primary function of a muffler is to reduce noise and vibrations of the exhaust emissions from the engine cylinder. The exhaust gases inside the engine cylinder are at a temperature of around 1200K, while the temperature at which the gases are expelled into the atmosphere is around 300K. The muffler also reduces backpressure. This increases the efficiency of the engine and also the power consumed. In this paper, a CAD model of a laminar flow performance muffler has been designed, which consists of a converging-diverging duct. These ducts contain perforations on their walls through which the exhaust gases scatter after passing in different directions. The material of a muffler should be resistant to corrosion at high temperatures, salt corrosion resistance from the high-temperature exhaust gas, vibration resistance and at the same time it should also possess sufficient strength to withstand high stresses and also be light in weight and affordable at the same time.
