Designation decoded
6 for 6 cylinders, EL for the Hanshin EL series, 40 for 400 mm bore. Specs: stroke 600 mm. Direct EL designation.
Background
The 6EL40, with a 400 mm bore and 600 mm stroke (S/B 1.5), is one of the larger Hanshin EL engines. The 400 mm bore offers more power than the standard EL models and approaches the power class of small MAN/WinGD/J-ENG engines.
Calculated metrics
Inspector checklist
- Cylinder liner: 400 mm × 6, 600 mm stroke, S/B 1.5
- Piston rings: Hanshin configuration
- Crosshead bearing: greater forces at 400 mm bore than on smaller EL models
- Camshaft: 6-cylinder
- Fuel pumps × 6: plunger/barrel
- Valve clearance: Hanshin manual
- Injection nozzles × 6
- Fuel: possibly HFO operation at 400 mm — is a separator fitted?
- Fuel filtration
- Stuffing box × 6: drainage
- Exhaust valve × 6: mechanical
- Turbocharger: 1× — no redundancy
- Scavenge air cooler
Logbook reference values
| Parameter | Expected | Deviation means |
|---|---|---|
| Exhaust gas temperature after cylinder | 335-410 °C at 85% MCR | Spread >15 °C → injection problem |
| Scavenge Air Pressure | 1.3-2.2 bar abs at MCR | Turbocharger |
| Engine speed | 160-280 rpm | Load/governor |
Common Failure Modes
Expert tips
- 💡 6EL40: at 400 mm bore, overlap with small MAN/WinGD engines begins — but Hanshin has its own design and spare parts
- 💡 With HFO operation: check separator plant and fuel preheating — not all Hanshin installations have full HFO treatment
