Common failures & inspection points

Zylinderliner-Scuffing: Lokales Verschweißen und Verschleiß zwischen Kolbenring und Linerinnenfläche verursacht durch unzureichende Schmierung oder Ölfilm-Zusam

Visuelle Inspektion des Liners auf Kratzer, Mikroschweißungen und Verfärbungen; lokale Schliff-Rauheit prüfen; bei Bedarf Liner nachhonen oder austauschen

wingd.com/media/odqa15kl/wingd-guid... www.cimac.com/cms/upload/workinggro...

Kolbenkrone- und Ringrillen-Verschleiß: Oberflächentragen, Verschleiß und Risse in Kolbenkrone und Ringrillen erfordern Dickenmessungen

Dickenmessgerät (z.B. Fischer Dualscope MP0) verwenden; Vergleich mit Richtwerten aus OM; Kolbenkrone auf thermische Verfärbung, Risse und Ablagerungen prüfen

wingd.com/media/odqa15kl/wingd-guid...

Brennstoffdruck-Anomalien und Rillenleckage: Zu hohes/zu niedriges Druck im Common-Rail-System und Brennstoff-Leckage aus Einspritzleitungen

Brennstoffdruck während Betrieb prüfen (Richtwert bei R1); Brennstoffrücklauf auf Undichtheiten kontrollieren; Inspektionsleitungen an Injektoren auf Lecks überwachen

wingd.com/media/ueqnlyk0/om_wingd-x...

Abgastemperatur-Unregelmäßigkeiten mit erhöhter Gaskonzentration in Kolbenunterseite: Asymmetrische oder unerwartete Abgastemperaturen stromabwärts einzelner Zy

Kontinuierliche Abgastemperatur-Überwachung pro Zylinder durchführen; bei Temp.-Unterschieden >30°C Zylinderkopf-Inspektionen einleiten; Gaskonzentration im Kolben prüfen

Servo-Ölsystem-Leckage und FLV/Brennstoffleitungs-Undichtheiten: Druckverlust im Servo-Hydrauliksystem und Brennstoffleck an Fuel Line Valves

Servo-Öldrück und -Durchfluss kontrollieren; alle Brennstoffleitungen und Ventilverbindungen visuell und unter Druck prüfen; Inspektionsgläser überwachen
