我单位在维修一台ED100型发动机时,将发动机解体后,发现四缸连杆瓦已经严重烧瓦,并与曲轴烧结在一起,瓦片随曲轴在连杆的大端孔中旋转了,因此,连杆大端孔就被磨损了。近数年来我国已引进了超过百万辆的进口汽车,在维修进口汽车的过程中,发现象上述的现象比较多,我们认为,一些车辆使用单位和个人,对进口汽车的性能、使用条件和要求了解不够,而造成了连杆等主要部件的严重损坏。连杆大端孔的磨损,除了与其工作条件有关外,还与使用保养有着紧密的关系。如缺少
When I repaired an ED100 engine, after disassembling the engine, I found that the four-cylinder connecting rod bush had been severely burned and was sintered with the crankshaft, and the tile was rotated with the crankshaft in the large end hole of the connecting rod , Connecting rod big end hole is worn. Over the past few years, China has imported more than one million imported cars. During the process of repairing imported cars, we found that there are many phenomena like the above. We think that some units and individuals that use the vehicles are not familiar with the performance, conditions of use and Requires insufficient understanding, which led to the connecting rod and other major components of the serious damage. Connecting rod end hole wear, in addition to its working conditions, but also with the use of maintenance has a close relationship. If missing
