　　2、大修流程、工序 The Process Design of The M272 Type of Engine’s 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. It is often easy to make mistakes for the newcomers， because of some informal training. So that it can’t reach to the expected standard. This thesis is designed a overhaul process to the M272 engine. It is overhauled and maintained， which is used the removal and check and installation and testing order and practical experience. Meanwhile it introduced to and checked the importance and road testing after overhauling in this thesis. Finally this thesis focus is designed some process cards.Keywords： M272 overhaul process 1 前言1.1目的隨著我國(guó)社會(huì)需求的牽引、政策法規(guī)的推動(dòng)和技術(shù)的進(jìn)步促使了現(xiàn)代汽車(chē)工業(yè)的迅速發(fā)展。
