摘　　要：对两种柴油机油在Mack T-11发动机试验后的油样进行分析。结果表明:在Mack T-11发动机试验中,随着烟炱含量的增加,烟炱颗粒的粒径逐渐增大;分散性能较差的油品,烟炱颗粒不断聚集,粒径明显变大,导致油品黏度大幅增加,同时磨粒磨损加剧;对于带EGR系统的Mack T-11发动机试验,油品需具备足够的碱值,以中和EGR系统带来的酸性气体。The analysis results of two diesel engine oils after Mack T-11 engine test show that during the Mack T-11 engine test,the soot particle size increases with increasing of the soot concentration.The poor soot dispersity leads to a significant viscosity increase of the oil and abrasive wear due to formation of larger soot particle through aggregation.The diesel engine oil needs high enough base number to neutralize the acids from the circulation of the exhaust gas in the Mack T-11 engine test with exhaust gas recirculation system.

关 键 词：Mack T-11发动机试验 烟炱 分散性能 磨损 碱值
