Project report for Automobile Silencer

The automobile industry all over India and it is growing at a very high rate and different Vehicles are always seen on the road. The production of silencer thus has a very good potential as it can be sold as original equipment and also in the replacement market. With the growth of the economy and increase in road transport, the demand of silencer is growing. Automobile   silencer   is   an  essential   part   of   any automobile. The  main function of silencer is to reduce  noise  of the vehicle. An automobile vehicle, while running on a road, produces  an intolerable  noise,  which, is otherwise controlled by  a  proper noise reducing device, will create a huge noise. The device,  used to minimise this noise is called ‘Silencer’ this device bring the noise  of  an auto engine to much  extract.  Until  comparatively recently,  the  design of silencers for automobiles  &  transport vehicle  engines  has  been largely  empirical  based  unreactive and dissipative  principles. Reactive silencers work  on  the principle  of  reflecting sound energy back towards  the  source. (But  may  also  provide some  energy  dissipation  by  crossflow depending  on  the  design).  Dissipative  Silencers  incorporate chambers  or  sections lined with sound  absorbent  materials  in which sould energy is absorbed. (and turned into heat). A muffler  or silencer is a device for reducing the noise  emitted by the  exhaust of an internal combustion engine especially a noise-deadening device forming part of the exhaust system of an automobile. Mufflers are installed within the exhaust system of most internal combustion engines. The muffler is engineered as an device to reduce the  loudness  of the  sound pressure  created by the engine by  acoustic quieting. The noise of the burning-hot exhaust gas exiting the engine at high speed is abated by a series of passages and chambers lined with roving  fiberglass insulation and/or resonating chambers tuned to cause destructive interference, wherein opposite sound waves cancel each other out.

Automotive exhaust systems are an integral component of the automobiles vehicles. The increased focus on the development of technologies for meeting international emission guidelines is expected to impact the use of exhaust systems in the automotive manufacturing industry. Factors such as regulatory obligations, increasing consumer awareness, and emergence of automotive companies that utilize advanced and eco-friendly technologies drive the growth of the global market for automotive exhaust systems. The key components of an automotive exhaust system include the engine, automotive exhaust manifold, automotive exhaust valve, automotive exhaust pipe, silencer, muffler, and the vehicle tailpipe. Automotive exhaust systems are majorly used for releasing the automotive exhaust gases from an internal combustion engine. The market is expected to expand with a CAGR of 7% over the forecast period 2021 to 2026. The growing number of vehicle coupled stringent noise regulations related to vehicle will drive the demand for automotive exhaust silencer market. Mostly, automotive exhaust silencer failure happens due to the effect of corrosion. It is due to the atmospheric conditions of the world and the acidic condensate deposit on silencer.
