The KONGSBERG cylinder liner monitoring system monitors the piston running performance
by measuring the temperature of the upper part of the cylinder liners. Increased
friction between the piston rings and the cylinder liner creates an elevated temperature
level leading to abnormal liner wear and potential piston ring breakage.
Temperature alarm limits can be individually set on the PC work station to give
early warning about high thermal load and potential cylinder liner scuffing. Additionally,
individual relay output alarms can be provided directly to the cylinder lubrication
units in order to temporarily increase the cylinder lubrication.
The KONGSBERG cylinder liner monitoring system consists of high quality temperature
sensors and one field-bus signal converter on each cylinder and one common PC work station.
