Improved monitoring of wear of bearings in a large two stroke diesel engine

摘要

An apparatus for monitoring wear of a crosshead bearing, a crankpin bearing and a main bearing in a large two stroke diesel engine, said apparatus comprising at least two sensors, wherein said sensors are arranged and configured for measuring a bottom dead centre level in a given cylinder relative to a fixed point of the engine, wherein said apparatus further comprises a controller configured to: receive a signal from each sensor; compensate each signal depending on an engine operating condition such as a speed; and determine whether a threshold value has been exceeded and if SO issue an indication of the exceeded threshold.
