Common failures & inspection points

Piston ring wear and breakage: insufficient piston ring and groove clearance leads to ring sticking at operating temperature, blow-by and potential ring breakage

Measure piston ring gap and perform ring movement test in grooves; monitor abnormal smoke development

www.brighthubengineering.com/marine...
Turbocharger damage: surging, blade damage, bearing failures lead to reduced scavenge pressure, black smoke development and elevated exhaust temperature

Inspect turbocharger for abnormal noise, measure charge pressure, check blades for damage

www.labordeproducts.com/news/freque...
Scheduled overhaul required after approximately 20,000 operating hours: reduced engine power, increased fuel consumption, black/blue exhaust, increased oil consumption

Review maintenance logbook, track operating hours, document exhaust color, monitor oil consumption

www.mhi.com/group/mvde/blog/12-warn...
Air cooler wear and corrosion: water condensation at scavenge air temperature <40–45 °C (slow steaming), rust formation due to oil mist and salt humidity

Spüllufttemperatur kontinuierlich überwachen (Sollwert: 50°C), Luftkühler-Entwässerung regelmäßig durchführen

marinediesel.co.in/scavenge-space-i...
Fuel injection system problems: too early injection or too low fuel temperature causes combustion knock during maneuvering; injection pressure

Check injection timing, maintain fuel temperature at approximately 50 °C, test injectors for pressure loss
