u
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
near the filter silencer. The following prerequisites must be fulfilled with regard to the tur-
bocharger to observe this limit value:
¡
Air-inlet system has been fitted
¡
All standard, noise-reducing measures
¡
Bellows at the air outlet has been acoustically insulated by the enginebuilder
Noise insulation, bellows
The enginebuilder is responsible for insulating the charge air/scavenging air line and the
charge air cooler.
