1. General
The cylinder lubricating system operates independently to lubricate the cylinder liners
and pistons. The engine control system (ECS) controls the adjustable load-related
supply rate of lubricating oil to each lubrication point.
1.1 Cylinder Lubricating Oil
During usual operation, a high-additive, alkaline cylinder lubricating oil is necessary.
The alkalinity of the lubricating oil that is chosen is related to the sulphur content of
the fuel (see 0750-1 Operating Media, paragraph 3).
1.2 Running-in
For running-in, approved cylinder lubricating oil is recommended (see 0410-1
Running-in of New Cylinder Liners and Piston Rings).
1.3 Cylinder Lube Oil Tank (Plant Side)
The cylinder lube oil tank (1, Fig. 1) for the cylinder lubricating oil is installed at a
specified height above the engine. This lets static pressure move the oil down through
the duplex filter (4).
The ECS sends signals to the control valve (2) on each cylinder lubricating pump.
This operates the pump and activates an injection. The pressure transmitter (3)
monitors the injection pressure.
