Inspector Detail

▸

Designation decoded

5X62-B – WinGD X-Serie, vollelektronischer 2-Takt-Kreuzkopfmotor ohne Nockenwelle. 'X62' = 620 mm Bohrung. '-B' = verbesserte Generation (optimierte Verbrennung, reduzierter SFOC, verbesserte Zylindergeometrie). 5 Zylinder. Bohrung 620 mm, Hub 2658 mm.

Background

The X62-B is the further developed version of the X62 with improved combustion efficiency. The B variant offers optimized piston/cylinder geometry, improved injection pattern and extended delta tuning options. Still UNIC-controlled with common rail injection. As a 5-cylinder configuration, the same torsional vibration considerations apply as for the X62. The B version can achieve lower SFOC values while simultaneously meeting stricter emission limits.

Inspector checklist

Logbook reference values

Parameter	Expected	Deviation means
Raildruck (HFO/VLSFO)	800–1000 bar (lastabhängig)	Deviation: pump/accumulator fault or injector leakage. More tightly tolerated in B version.
Auslassventil-Leckölmenge	< Herstellergrenzwert (B-Version ggf. niedrigere Grenzwerte)	Steigende Tendenz: Spindelverschleiß, Sitzring-Erosion.
Zylinderauslass-Temperatur (Spreizung)	Max. ±12–15 °C vom Mittelwert	Deviation: combustion uneven, check injector or exhaust valve.
Cylinder liner wear	0.02–0.08 mm/1000 Bh (B-Version tendenziell niedriger)	Überhöht: CLO-Rate, Kolbenringe, Brennstoffqualität prüfen.
SFOC (spez. Kraftstoffverbrauch)	Gemäß B-Testbed-Protokoll (typ. 2–4% besser als Basis-X62)	Deterioration: injector degradation, turbocharger fouling or incorrect Delta Tuning setting.
Barred Speed Range Einhaltung	Gemäß Torsionsschwingungsgutachten (5-Zyl.)	Nichteinhaltung: Risiko von Kurbelwellen-/Kupplungsschäden.

Common Failure Modes

Injector wear (B-specific nozzles)

Symptoms: ['Erhöhter SFOC', 'Abgastemperatur-Asymmetrie', 'Smoke development at part load']

Causes: Kavitationsverschleiß an optimierten Düsenlöchern, Brennstoff-Kontamination, Überschrittenes Wartungsintervall

Preventive: B-spezifische Injektorüberholungsintervalle einhalten. Nur Original-WinGD-Ersatzteile für B-Düsen verwenden.

Auslassventil-Korrosion

Symptoms: ['Kompressionsverlust', 'Steigende Leckölmenge', 'Abgastemperatur-Anstieg']

Causes: Hot corrosion due to fuel contamination, Fehlerhafte Ventil-Rotation, Thermische Überlastung

Preventive: Regelmäßige Ventilinspektion. Rotocap-Funktion prüfen. Brennstoff-Behandlungsanlage in einwandfreiem Zustand halten.

UNIC-Kommunikationsstörung

Symptoms: ['Zylinderabschaltung', 'Leistungsreduktion', 'Alarms on bridge and in engine room']

Causes: Cable breakage due to vibration, Feuchtigkeitseintritt in Steckverbinder, Firmware-Inkompatibilität

Preventive: Check cabling and connectors at every major overhaul. Software updates according to WinGD Service Letters.

Torsionsschwingungsschäden (5-Zylinder)

Symptoms: ['Abnormale Vibrationen', 'Risse im Schwingungsdämpfer', 'Kupplungsverschleiß']

Causes: Verweilen im Barred Speed Range, Defekter Schwingungsdämpfer, Mangelhafte Überwachung

Preventive: Barred-Speed-Range-Durchfahrt zügig durchführen. Schwingungsdämpfer turnusmäßig prüfen.

Common failures & inspection points

Fuel valve carbon deposits / fuel system blockages in low-load multi-fuel operation

Inspect fuel valve nozzle spray pattern during top-overhaul; monitor differential pressure across fuel filter; verify fuel heating system temperature compliance

Piston crown thermal cracking and top-land spalling under extreme load or fuel quality variations

Measure piston crown surface condition using borescope; check for micro-cracks in top land; examine combustion bowl geometry; compare cylinder-to-cylinder pressure readings

Cylinder liner scuffing/scoring in dust-contaminated conditions or with inadequate air filtration

Perform liner diameter measurement service at each overhaul; document wear rate trending; inspect piston rings for abnormal wear patterns; check air inlet filter condition

Turbocharger surge and cavitation erosion in unsteady loading (e.g., dynamic positioning vessels)

Monitor turbocharger bearing temperatures during mode transitions (gas-to-diesel); inspect turbocharger for cavitation pitting on impeller; verify surge line compliance in operational envelope

Fuel gas supply system pressure regulation instability (iGPR unit hysteresis) under rapid load changes

Perform fuel gas system pressure step-response test during commissioning; verify regulator response time <500ms per specification; conduct annual gas line tightness test with ultrasonic detection
