摘  要:在发动机开发过程中,如何及时地发现问题和快速地排查及解决问题,是台架试验过程的一项重要综合能力的体现。本文通过在委托公司进行的某发动机试验运行过程中,曲轴箱通风口处出现冒白烟的现象,分别对过程数据,例如:冷却系统、增压系统、机油压力及活塞漏气量等,以及拆机分解两方面进行对比分析、排查,得出分析与拆解的结果两者逻辑上的一致性,并具体列举了本次试验过程中存在的一些问题,要求查缺补漏,吸取教训,在以后的试验开发过程中规避类似的问题,以提高发动机试验的开发成功率。In the process of engine development, bench test is an important part, how to find problems in time and quickly troubleshoot and solve problems is an important comprehensive ability of bench test. In this paper, white smoke was appeared at the crankcase vent during the operation of the engine on the test stand of an outsourced company, and the process data were as follows: Cooling system, Supercharging system, oil pressure and piston leakage, etc., and teardown composition, this paper compares and analyzes two aspects, it is concluded that the results of the analysis and disassemble both are logical consistency, and lists some problems in the process of the test, these are required check, lessons learned, in the later test to avoid similar problems in the development process, to improve the success rate of engine test development.
