A ship exhaust silencer reduces the noise produced by an internal combustion engine as it expels exhaust gases.
The ship exhaust silencer is used to reduce the noise of an internal combustion engine. It can also include a spark arrester or devices to treat CO2 emissions, damp vibrations, etc.
The exhaust silencer is generally cylindrical to fit the exhaust pipe, though size and shape may vary. It can be made of a variety of materials (steel, composites, alloys) capable of resisting high temperatures.
Several factors must be considered in order to choose a silencer adapted to a particular engine. Suppliers can furnish or design the best unit for a given vessel.
