With the current host used more and more oil ship inferior makes the cylinder liner more bad working conditions, cylinder liner wear espe
3、cially the abnormal wear of cylinder liner on the surface of the study is particularly important. Through the understanding of the cylinder liner wear types of abnormal cylinder and its failure on the structure of the structure characteristics and material properties, making clear of the cylinder li
4、ner wear mechanism. Analysis of the cylinder abnormal wear, cause of from the design, manufacturing, installation and use, maintenance, repair, so as to work out, this paper discusses the formation of the abnormal cylinder liner wear law and its harm, puts forward the prevention to solve all wear th
5、e method of fault. This research helps to grasp the production mechanism of wear and rule to take active measures to prevent and repair technology. On diesel engine design installation, use maintenance has some significance, are also good for improving Marine diesel engines life and the use benefit
