摘要: 以Mack T-9发动机台架为研究对象,分析了8种柴油机油在500 h台架试验过程中的烟炱含量、黏度、金属含量、总酸值、总碱值、硝化物和磷元素化学状态等性质的变化过程,探索了柴油机油性质的变化对缸套磨损的影响。试验结果表明:黏度稳定、抗氧化能力强和总碱值偏高的柴油机油有助于降低发动机磨损,分析结果将对高品质柴油机油的开发提供指导。

Abstract: The changes in soot content, viscosity, mental content, total acid value, total alkali value, nitrification and phosphorus chemical state of eight kinds of engine oils in 500-hours Mack T-9 bench test were analyzed to investigate the effects on the cylinder liner wear. The results indicate that the diesel engine oil with steady viscosity, strong anti-oxidization ability and high total alkali value is useful to improve the anti-wear performance. The knowledge from the results is helpful to develop high-grade diesel engine oils.

Key words: diesel engine oil, Mack T-9 engine bench, anti-wear performance, physicochemical properties
