| 摘要:发动机分别按两种磨合规范进行磨合,根据磨合后各摩擦副的表现,结合润滑油光谱分析,得出不同磨合规范对发动机各摩擦副的影响。研究表明:发动机磨合时的载荷、转速应遵循逐级提高的原则；柴油机的磨合规范不尽相同,应针对发动机的强化程度和标定参数来确定磨合的转速、载荷以及磨合时间。 |

| Abstract:The running-in of engines are conducted according to two sets of specifications. Based on the performance of each friction pair after running-in, and combined with the analysis of lube oil spectra, the influence of different running-in specifications on engines’ friction pairs are obtained. The analysis show that the load and speed of running-in should follow the principles of increasing step by step, the running-in specifications are different, thus the speed, load and lasting time of running-in should be determined by the strengthening level and calibration parameters. |
