4.1 Noise emissions
WARNING
Hazards due to noise
Noise can cause impaired hearing, damage to health, mental disturb-
ances, diminished attention and irritation.
u
Always wear ear protection when the engine is running.
u
When the sound pressure level is above 85 dB(A), always wear ear
protection.
Wear ear protection.
The sound pressure level (A-weighted) of emissions is measured at a dis-
tance of 1 metre from the turbocharger.
The highest sound pressure level of emissions
1)
reaches a maximum of
105 dB(A) near the filter silencer and over the entire speed range.
The following prerequisites must be fulfilled on the turbocharger in or-
der to observe this limit value:
¡
Fitted air-inlet system
¡
All standard, noise-reducing measures have been taken
2)
.
¡
The bellows at the air outlet have been perfectly insulated acoustic-
ally by the engine builder. He is also responsible for insulating the
charge air / scavenging air line and the charge air cooler.
1)
Directive 2006/42/EC, 1.7.4.2 / u / Paragraphs 5 + 7 :
A-weighted emission sound pressure level
2)
In the event of divergent insulation designs, the engine builder must
ensure that equivalent acoustic insulating measures are taken.
