摘　　要：高速高负荷大功率摩托车发动机凸轮轴与挺杆间载荷高,使用传统磨合油,在磨合过程中凸轮轴-挺杆出现严重擦伤,导致磨合合格率低。凸轮轴-挺杆处于边界润滑状态,解决其严重磨损、擦伤与烧结的关键在于提高磨合油的极压性能。在配方设计上,选用较高黏度的基础油,并以极压抗磨剂为主剂,通过正交试验,确定添加剂的最佳添加量,研制出满足该型号摩托车发动机磨合要求的专用磨合油,使磨合合格率达到95%以上。该油的配方组成与传统磨合油有显著差异,其最重要的性能特征为具有优异的极压性。The severe scratch occurred on the surface of camshaft and jib when the traditional running-in oil was used to grind the parts of high speed and large power motorcycle engine,because the duty between camshaft and jib is heavy and the lubricating means between them is boundary lubrication.In order to prevent scratch,the extreme-pressure performance of running-in oil must be greatly enhanced.The formula of the running-in oil is composed of higher viscosity base oil and several kinds of additives,and the extreme-pressure agent is dominant among additives.The special purpose running-in oil was developed by means of orthogonal experiment,which can completely meet the running-in needs.The most important difference between the traditional running-in oil and the special purpose running-in oil is that the latter one is provided with outstanding extreme-pressure performance.
