MODELLING AND ANALYSIS OF TWO WHEELER MUFFLER

Mechanical Engineering

Muffler is a crucial a part of the engine system and is usually employed in an system to reduce sound transmission caused by exhaust gases. the new gases generated from the combustion of fuel passes through the system of the car as they form the passage for the new gases and are released into the atmosphere, hence they're subjected to very warm temperature. The system of automobile consists of three parts as manifold, convertor and silencer, out of these silencer have very short generation as there's lot of restriction provided to the flow of hot gases thanks to complex geometry so as to scale back the background level. Hence gases staying longer during this section as compared to other two parts of exhaust. This area must be focused during design phase. The uniform heat distribution over the complete system is very important for ensuing enhanced lifetime of elements within the subsystem. Exhaust noise is one in every of the most source of car and exhaust systems are developed to attenuate noise meeting required levels and sound quality emissions supported environmental norms. to beat this problem muffler should be modified. By minimizing pressure drop surely reduces backpressure. This work focuses on the exhaust mufflers for two-wheeler vehicles. Study will include flow analysis and also thermal analysis to be performed on the present design of the exhaust muffler and the muffler are going to be designed within the solid works to satisfy the wants. Exhaust gas temperatures, Velocities and back pressure are evaluated and verified through Finite Element Analysis package ANSYS
