6.9 Scuffing
Figure 11 shows an incident of scuffing seen during normal running conditions. The cause of this is
unknown but the sensor data did show it in enough time to reduce the load and increase the cylinder
lubricant feedrate to that cylinder.

6.10 Conclusions
•
LinerSCAN monitors the condition of slow speed diesel engine liners and rings.
•
Equipment which is still bedding in is more susceptible to problems caused by out of
specification parameters such as fuel with high catalyst fines.
•
Trending of cylinder wear is very important. Trending after damage events can show if
permanent damage has occurred or if the situation is improving.
•
When liners and rings are replaced together they bed in sooner than when only a rings are
replaced.
•
Regular start/stopping of the engine increases wear rates.
•
Feedrate optimisation programs and assistance from the engine manufacturer reduce cylinder
oil costs.
