奔驰M272发动机大修流程设计
随着汽车工业的进一步发展，进口汽车保有量日益攀升。发动机是汽车的心脏部位，汽车发动机维修、保养的好坏，直接关系到汽车的动力性和经济性。目前进口发动机的大修上，没有一个标准的流程，对于初入行业的新手来说，得不到正规的学习，难免发生错误，
使维修的发动机达不到预期的标准，本文是针对奔驰轿车M272发动机的大修工作，设计一个较为合理的大修流程，即主要采用拆、检、装、验的顺序，结合维修实践中的操作经验，对发动机进行维修与保养，同时对发动机的重要部件进行介绍、检查，以及维修后对整车进行检验和路试，最后设计出部分重点工序的工序卡。

Abstract考三轮车驾驶证多少钱
With the further development of automobile industry，the imported cars’ number is raised day after day. The engine is very important, which is like one’s heart. The engine maintenance and overhaul good or not，that relate to the power and the economize of automobile，now there is not any standard process for the imported engine.
