Abstract
The causes of wear in liners rings and ring grooves of marine diesel engines are numerous and complicated sothat wear in these components became a problem especially in slow speed engines.This problem had been studied by many researchers,but each of their studies concentrated on one or the other of the causes of wear.In this study a method for prediction and control of the total expected wear rate in liners is developed.
Chapter one:reviews in machine components in general definition main types and methods of measurement and detection.
Chapter two:starts with comparison between the wear rates in liners of slow and medium speed engines.Those rates are much higher about ten times in slow speed than in medium speed engines so the present study concentrates on the first type of engines.This chapter then discusses the mechanisms of the main types of wear affecting the cylinder components.
Chapter three:discuss in detail the causes of wear in liners,rings and ring grooves of slow speed engines.It could be due to operating conditions or due to fuel or oil quality,or any other reason.By studying these causes the methods used to resist each of them are known.
Chapter four:describes what canbe seen in worn components.There are descriptions and photographs for liners and rings suffering different types of wear in these components and the wear profiles obtained by neasurement.After discussing the wear limits it was conculed that we also need to know the wear rates to estimate the expected service life of the components and schedule the cylinder overhauls.
