Turbolader-Verschmutzung durch Kohle- und Ascheteilchen im Abgas bei Niedriglastarguetrieb, BMEP-Rückgang und Verbrennungsverschlechterung
Kolbenringleckage und Brennstoffverdünnung (>2-3%) durch Verschleiß an Zylinderlauffläche/Kolbenringen, erhöhter Blowby und Öl-Kontamination
Zylinderliner-Verschleiß durch korrosive Verbrennung bei schwefelhaltigem Brennstoff; Inspektionskriterium: Verschleiß nach Höhe der Gleitfläche, max. zulässig
Wellenlager-Verschleiß durch Öl-Kontamination; wöchentliche Prüfung auf Wassereintritt (<2% zulässig) und 3-Monats-Analyse auf Verschleißmetalle (Fe, Cu) erford
