Always wear ear protection when the engine is running. When the sound pressure level is above 85 dB(A), always wear earprotection.Wear ear protection.The sound pressure level (A-weighted) of emissions is measured at adistance of 1 metre from the turbocharger.The highest sound pressure level of emissions 1) reaches a maximum of105 dB(A) near the filter silencer and over the entire speed range.The following prerequisites must be fulfilled on the turbocharger in orderto 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 acousticallyby the engine builder. He is also responsible for insulating the chargeair / 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 level2) In the event of divergent insulation designs, the engine builder mustensure that equivalent acoustic insulating measures are taken.44.1
