Auxiliary Engine (Generator Set) · Auxiliary Engines
Onboard a modern container ship operating under 60 Hz electrical systems, the Wärtsilä 7LW26-GS-60Hz engines provide reliable power generation. These engines are typically used in low-load operations where piston ring wear and peeling can occur due to inadequate oil film at lower loads. Operators must regularly inspect piston crowns and rings through scavenge ports, monitor the residual Base Number (BN) of cylinder oil, and ensure iron content stays below 500 mg/kg to prevent such issues. Additionally, cold corrosion in cylinder liners during low-load operations can lead to acidic condensation; maintaining cylinder cooling water outlet temperature close to its alarm limit is crucial. Proper cylinder oil selection, like Mobilgard 5100, helps mitigate these problems.
