Improved monitoring the wear of bearings in a two-stroke large Diesel engine.

摘要

The invention relates to an apparatus and method for monitoring wear of a crosshead bearing, a crank pin bearing and a main bearing in a two-stroke large Diesel engine. The device comprises at least two sensors which are arranged and configured to measure a level of a bottom dead center of the crosshead or a sliding block in a specific cylinder with respect to a fixed point of the motor. In a learning phase, a table with reference values ​​for compensating for engine operating conditions is generated. The normal operation comprising the steps of: receiving a signal from each sensor; Compensate each signal (420) with a reference value in function of the current engine operating condition; Determining whether a threshold has been exceeded (450), and if this is the case, outputting a display of the exceeded threshold.
