Project Report For Automobile Silencer


Project report for Automobile Silencer is as follows.

A Silencer is a device that reduces the noise generated by the exhaust of an internal combustion engine, particularly a noise-deadening device that is part of an automobile’s exhaust system. Most internal combustion engines have mufflers fitted in their exhaust systems. The muffler is designed as an acoustic quieting device to lower the loudness of the engine’s sound pressure. A system of tunnels and chambers lined with roving fibreglass insulation and/or resonating chambers calibrated to produce destructive interference, where opposite sound waves cancel each other out, reducing the noise of the engine’s burning-hot exhaust gas departing at high speed. A car silencer is a necessary component of every vehicle.

The primary function of a silencer is to minimise vehicular noise. When an automotive vehicle is running on the road, it makes an uncomfortable noise that, if not regulated by a good noise lowering mechanism, creates tremendous noise. The equipment used to reduce noise is known as a ‘Silencer.’ This gadget reduces the noise produced by an automobile engine. Until recently, the design of silencers for automotive and transportation vehicle engines was primarily based on empirically proven unreactive and dissipative principles. Reactive silencers operate by reflecting sound energy back towards the source. (However, depending on the design, crossflow may provide some energy dissipation.) Dissipative Silencers are chambers or sections lined with sound-absorbing materials that absorb sound energy. (and was transformed into heat).

Market potential & Strategy

Automotive exhaust systems are an essential component of automobiles. The growing emphasis on developing solutions to fulfil international emission criteria is likely to have an influence on the use of exhaust systems in the automobile manufacturing sector. The worldwide market for automotive exhaust systems is growing due to factors such as regulations, increased consumer awareness, and the rise of automotive businesses that use sophisticated and eco-friendly technology. The engine, automotive exhaust manifold, automotive exhaust valve, automotive exhaust pipe, silencer, muffler, and vehicle tailpipe are the main components of an automobile exhaust system. Automotive exhaust systems are primarily utilised to expel automotive exhaust gases from internal combustion engines. Over the projected period of 2021 to 2026, the market is estimated to grow at a CAGR of 7%. The rising number of vehicles on the road, along with severe noise laws, will boost the need for automotive exhaust silencers. Corrosion is the most common cause of automobile exhaust silencer failure. It is caused by the world’s atmospheric conditions and the acidic condensate deposit on the silencer. Automotive exhaust silencers are made of composite materials (glass fibre, carbon fibre, stainless steel) for this function.

The automotive business is expanding rapidly all over the world, and various automobiles may constantly be seen on the road. As a result, the manufacture of silencers has a high potential since it may be marketed as original equipment as well as in the replacement market. The need for silencers is increasing as the economy grows and road transportation expands. Because the need for automotive vehicles such as scooters, motorcycles, autorickshaws, mopeds, and so on is rising on a daily basis in the country, there is a significant opportunity for auto silencers, the demand for which is projected to rise by 8 to 10% in the near future.
