Cylinder oil system
The cylinder oil system supplies cylinder oil onto the cylinder liners. The engine control system
(ECS) controls the adjustable load-related supply rate of cylinder oil to each lubrication point.
The engine has an automatic pre-lubrication sequence. At each engine start the ECS automatically
starts this sequence. This makes sure that the cylinders are sufficiently lubricated. The sequence
includes a specified number of lubrication pulses. For the specified number refer to chapter 11
Technical data.
NOTE:
You can also start the pre-lubrication sequence manually.
For the schematic diagrams, refer to section
13.1 Schematic diagrams - general
.
The cylinder oil is used only one time.
The cylinder oil system has the parts that follow:
•
Oil pipes
The oil pipes connect the items that use oil.
•
Duplex oil filter
The duplex oil filter (004) filters the oil before it flows to the cylinder lubricating pumps. The
change-over valve makes it possible to shut off one filter chamber.
•
Cylinder lubricating pump
Each cylinder has a cylinder lubricating pump (003). Servo oil operates the cylinder
lubricating pumps. The ECS controls the cylinder lubricating pumps.
•
Lubricating quill
The lubricating quills (002) spray cylinder oil onto the running surface of the cylinder liners.
The lubricating quills are installed on the circumference of the cylinder liner.
•
Oil sample valve
To drain a sample of dirty oil, use the oil sample valve (001) at the cylinder liner underside.
•
iCAT (if installed)
The iCAT system (integrated Cylinder lubricant Auto Transfer system) automatically selects
the cylinder oil with the correct base number (BN) related to the fuel in use. If necessary,
the iCAT system automatically changes over the cylinder oil. The change-over valve (007)
is near the cylinder lubricating pump (003). Thus the correct cylinder oil is immediately
supplied to the cylinder liner. The engine control system (ECS) controls the iCAT system.
NOTE:
You have to enter the correct basic values (eg the sulfur content of the fuels) for
the iCAT system in the RCS, refer to the related documentation.
