浅析汽车发动机气缸磨损

A Brief Analysis on Cylinder Wear of Automotive Engine

发动机是汽车动力的来源,车辆在运行过程中,由于各种因素的影响,各组合件配合副的磨损,将导致发动机使用性能的变坏。在发动机的修理过程中,气缸磨损程度的大小是判断发动机是否需要进行大修的重要标志。大多数汽车往往由于使用和维护不当、修理时检查不到位、修理方法不当、装配不合理等,造成发动机气缸的磨损严重,影响了车辆的技术状况。如何减少气缸的磨损,延长发动机大修里程,从而使发动机使用寿命提高,是一个值得探讨的课题。

The engine is the source of automotive power, hut due to the influence of various factors, parts wear will worsen the en- gine serviceability during the operation of vehicle. In engine re- pair, the degree of eylinder wear determines whether the engine needs to be overhauled. Most of the severe cylinder wears are eaused by improper use and maintenance, imperfect eheek, im- proper repair melhods and unseientifie assembly, resuhing in se- vere engine eylinder wear, affeeting the technical condition of ve- hicles. How to rednee eylinder wear and extend ＇;interval of engine overhaul to improve the engine service life would be a topic worthy of discussion.
