Wartsila Bulletin RT-161 Cylinder lubrication

Provides information and guidance concerning the cylinder lubrication of Wärtsilä 2-stroke engines.
The piston running behaviour of 2-stroke engines is exhibiting an ever growing complexity. The key internal factors are the changes of operation patterns (e.g. slow steaming).

Provides information and guidance concerning the cylinder lubrication of Wärtsilä 2-stroke engines.
The piston running behaviour of 2-stroke engines is exhibiting an ever growing complexity. The key internal factors are the changes of operation patterns (e.g. slow steaming).

New tuning options including fuel saving retrofit packages might also be considered. On the other hand, the very wide range of cylinder lubricant quality, the
use of various fuels due to complex environmental regulations and the corresponding solutions constitute external factors that may significantly influence the piston running
behaviour of the engine.

In this Technical Bulletin, the correct setting of the cylinder lubricating system should
allow the following goals to be met:
• Ensure the optimal and fit for purpose supply of lubricant to the piston ring – cylinder liner system, while keeping it at the minimum.
• Ensure the reliable operation of piston running components.
• Ensure the achievement and/or the extension of the time between overhauls of the piston running components.
