摘　　要：采用对比试验的方法,研究了柴油机缸套-活塞组磨损对气缸漏气率和燃油消耗量的影响。针对柴油机缸套-活塞组不同的磨损运行状态,利用机身振动信号及油样光谱分析方法进行了研究。结果表明,机身振动信号、油样光谱分析方法可以对缸套-活塞组磨损运行状态实现有效的监测,并为多信息融合技术提供试验方法和数据基础。The comparison experiment method was used in this paper to study the influence of the diesel cylinder - piston group wear on the gas leakage rate and specific fuel consumption. The different wear conditions of cylinder - piston group were analyzed from the vibration signal of the engine surface and oil spectrum methods. The result shows that the methods mentioned in this paper can be used to monitor the wear condition of cylinder- piston group effectively, and this paper provides some experimental methods and data base for applying the multivariate information fusion technology.
