Inspektion

Inspektor-Detail

Häufige Probleme

Cylinder liner bore polishing or scuffing from poor HFO combustion or incorrect lube oil BN
Exhaust valve burning or seat recession from high thermal load
Turbocharger fouling and bearing wear from HFO soot deposits
Fuel injection equipment wear (plunger/nozzle) from HFO abrasives if fuel treatment is inadequate
Piston ring sticking or collapse from carbon buildup on poor-quality fuel
Charge air cooler fouling reducing power output
Crankcase oil contamination from liner blow-by on worn units
Common-rail accumulator or high-pressure pump wear

Prüfliste

Cylinder liner bore inspection (scuffing, polishing, wear pattern) via borescope
Exhaust valve seat condition and rotation check
Exhaust gas temperature spread between cylinders
Turbocharger boost pressure and speed vs load
Piston ring and groove wear at overhaul
Fuel injection equipment wear check (plunger, nozzle spray pattern)
Lube oil analysis (BN depletion, wear metals, insolubles)
Charge air cooler pressure drop
Crankshaft deflection readings
HFO fuel treatment plant performance (centrifuge, viscosity control)

Wartungsintervalle

Lube oil analysis	every 500 h or per the manufacturer's schedule, more frequent on HFO
Fuel injection equipment overhaul	typically 8000-12000 h depending on fuel quality - confirm against the manufacturer's schedule
Exhaust valve overhaul	typically 8000-16000 h depending on load and fuel - confirm against the manufacturer's schedule
Turbocharger cleaning/inspection	2000-4000 h running clean, full overhaul per the manufacturer's TBO
Piston/liner inspection	at major overhaul, typically every 12000-16000 h - confirm against the maintenance plan
Crankshaft deflection check	at each major overhaul or per class requirement

Typische Intervalle für diese Bauart, keine Herstellerangabe für Ihr Modell. Verbindlich ist das Handbuch des Herstellers.

Typische Verschleißgrenzen

Cylinder liner wear	typically 0.03-0.08 mm per 1000 h for this bore class on well-treated HFO - confirm against the engine's own manual
Piston ring end gap	typically 1.5-3.0 mm for a 460 mm bore class - confirm against the manufacturer's manual
Main/big-end bearing clearance	typically 0.30-0.55 mm depending on shell design at this bore size - check the manufacturer's limits
Exhaust valve seat recession	condemning limit is engine-specific; track the trend against baseline rather than a single reading - confirm against the manufacturer's manual

Die Bereiche sind für diese Bauklasse typisch. Maßgeblich sind stets die Herstellerunterlagen zur jeweiligen Seriennummer.

Kritische Ersatzteile

Piston ring set (this bore/family)
Cylinder liner
Exhaust valve and seat set
Fuel injection nozzles
Turbocharger repair kit (bearings, nozzle ring)
Cylinder head gasket
Main/big-end bearing shells
Charge air cooler element

Sicherheit

High-pressure common-rail fuel system remains pressurised after shutdown - depressurise per the manufacturer's procedure before opening
HFO handling - hot fuel lines under pressure carry a burn risk from leaks
Crankcase explosion risk - observe the cool-down period before opening crankcase doors after a bearing-temperature alarm
Heavy rotating and reciprocating masses at low rpm - lock out before entering the crankcase
Starting air system holds stored pressure - isolate and vent before maintenance
Hot exhaust manifold and turbocharger surfaces

Klassenbesichtigung

Normally surveyed under Continuous Survey Machinery (CSM) with class crediting the owner's planned maintenance system; expect focus on crankshaft deflection records, cylinder condition (liner/piston/valve) trending, turbocharger overhaul records, and governor/overspeed and safety trip testing at survey.

Geschätzte Lebensdauer: Medium-speed Wartsila 46-class engines are commonly operated to 32,000-40,000 h between major overhauls under good fuel and maintenance conditions, with total service life well beyond 100,000 h achievable through successive overhauls; actual intervals depend on load factor and fuel quality.
