WARNING
Danger due to noise
Exposure to noise can harm the hearing system, impair health and the psy-
chological state and may lead to lack of attention and irritation.
When the engine is running, always wear ear protection.
Always wear ear protection if the sound pressure level exceeds 85 dB(A).
Wear ear protection.
The emission sound pressure level (A-weighted) is measured at a distance of 1 meter from
the turbocharger.
The highest value of the emission sound pressure level
1)
reaches a maximum of 105 dB(A)
near the filter silencer. The following prerequisites must be fulfilled with regard to the turbo-
charger to observe this limit value:
Air-inlet system has been fitted
All standard, noise-reducing measures
2)
have been fitted
Bellows at the air-outlet has been acoustically insulated by the enginebuilder (see Figure
The enginebuilder is responsible for insulating the charge air/scavenging air line and the
charge air cooler.
