Exhaust Silencer

Definition - What does Exhaust Silencer mean?

An Exhaust Silencer, also known as a muffler is a device that is used to reduce the amount of sound emitted by the exhaust of an internal combustion engine. The device is also used whenever air or gases like natural gas, nitrogen or hydrocarbon gases are emitted to the atmosphere under high pressure so as to reduce the loudness of the sound.

Petropedia explains Exhaust Silencer

Whenever air or some gases like exhaust gas from the internal combustion engine in the industrial unit are emitted to the atmosphere under high pressure, they cause high sound/noise levels. An exhaust silencer is installed in the exhaust system to suppress the sound so as to safeguard the workforce in the industrial unit or public against noise pollution. It is basically used as a soundproofing device. The silencer is also used to prevent any sparks and other flammable debris from exiting the tailpipe. The main disadvantage of an exhaust silencer is that it increases back pressure and this reduces the efficiency of the engine.
