随着汽车发动机的不断磨损及其内部某些零部件的老化,会出现烧、漏机油的故障。过去,解决这类问题的方法是把发动机解体,更换一些破损的零部件,以达到恢复摩擦配合副的间隙,改善密封性能的目的。由于发动机在制造厂是在恒温超净的状态下装配的,而我国修理企业还达不到这样的作业环境,加之有时更换的一些零部件质量差,致使经修理后的发动机各摩擦副间隙及配合接合面恢复不到原车的标准,往往出现事与愿违的结果,摩擦副的配合间隙不但没有得到完好的恢复,烧、漏机油的现象更加严重,大大影响了发动机的寿命。最近,我们在不解体发动机的情况下,使 With the continuous wear and tear of the car engine and the aging of some of its internal components, there will be burning, leakage of oil failure. In the past, the solution to such problems was to disassemble the engine and replace some broken parts to achieve the purpose of restoring the clearance between the friction partners and improving the sealing performance. As the engine assembly in the factory under the condition of constant temperature and cleanliness, and our country’s repair business also can not reach such a working environment, coupled with the sometimes poor quality of some of the replacement parts, resulting in the repair of the engine after the friction between the Deputy and With the joint surface can not be restored to the original car’s standards, often unavoidable results, friction pair with the gap not only did not get a good recovery, burning, leakage of oil is more serious, greatly affecting the life of the engine. Recently, we made it possible without disintegrating the engine
