When the engine is running, always wear ear protection.
u
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 air inlet. The following prerequisites must be fulfilled with regard to the turbochar-
ger 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
The enginebuilder is responsible for insulating the charge air/scavenging air line and the
charge air cooler.
