无论在苏联或其它国家,对研究发动机的起动磨损问题都进行了大量的工作。可是直到现在,对发动机起动时气缸——活塞组磨耗的动力学问题还不是完全清楚的,而制订减小发动机起动磨损的这个或那个措施都要取决于这个问题的解决。最近采用《切痕》法测量发动机气缸套筒起动磨损的大多数研究者,基本上都用随着发动机加温过程的结束而终止的腐 No matter in the Soviet Union or in other countries, a great deal of work has been done on studying the starting wear of engines. Until now, however, the dynamics of cylinder-piston group wear at engine start-up were not fully understood, and the development of one or other measures to reduce engine wear would depend on the solution to this problem. Most researchers who recently used the “kerf” method to measure the starting wear of an engine cylinder sleeve basically used a rot that ended with the warming of the engine
