Cylinder oil
When you do a change-over of the fuel, you must make sure that you change to the correct cylinder
oil at the same time. This prevents damage of the piston running system because of an incorrect
BN. For more data refer to the related procedures.
8.10.4.1
Engine with iCAT
If the engine has an iCAT system (integrated Cylinder lubricant Auto Transfer system), WinGD
recommends as follows, when you change-over the fuel:
•
If the iCAT system is in auto mode, the iCAT system automatically changes-over the cylinder
oil at the correct time.
•
If the iCAT system is in manual control (no iCAT functionality mode), you have to manually
change-over the cylinder oil at the same time as the diesel fuel change-over.
8.10.4.2
Engine without iCAT
If the engine has no iCAT system (integrated Cylinder lubricant Auto Transfer system), WinGD
recommends to monitor the change-over of the cylinder oil. Do a calculation of the cylinder
lubricant quantity and make sure that you know the cylinder lubricating feed rate, refer to
1
Make sure that you know the cylinder lubricant quantity that is between the change-over
valve and the lubricating quills including the measurement tube.
2
Calculate the related lead time that the cylinder oil has to get to the lubricating quills.
3
Use this lead time to have the correct timing for the change-over of the cylinder oil.
NOTE:
When you change from MDO to HFO, WinGD recommends to start the change-over of
the cylinder oil from low BN to high BN already inside the ECA zone. This prevents
operation with high sulphur fuel and low BN cylinder oil.
