WARNING
Hazards due to noise
Noise can cause impaired hearing, damage to health, mental disturb-
ances, diminished attention and irritation.
Always wear ear protection when the engine is running.
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 order
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 acoustically
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 en-
sure that equivalent acoustic insulating measures are taken.
