11.3.7.4 Conventional exhaust gas silencer (5R02)
Yard/designer should take into account that unfavourable layout of the exhaust system (length
of straight parts in the exhaust system) might cause amplification of the exhaust noise between
engine outlet and the silencer. Hence the attenuation of the silencer does not give any absolute
guarantee for the noise level after the silencer.
When included in the scope of supply, the standard silencer is of the absorption type, equipped
with a spark arrester. It is also provided with a soot collector and a condense drain, but it
comes without mounting brackets and insulation. The silencer can be mounted either
horizontally or vertically.
The noise attenuation of the standard silencer is either 25 or 35 dB(A). This attenuation is valid
up to a flow velocity of max. 40 m/s.
