摘　　要：为研究不同质量比例润滑油对柴油机颗粒物排放的影响,利用燃油品质分析仪以及扫描电子显微镜分别对燃油品质和颗粒物形貌粒径进行观察分析。研究表明:随着润滑油质量的增加,十六烷值、芳香烃含量及T90也呈现上升趋势,这三者上升导致细颗粒物的增加。从颗粒物的形貌变化和粒径分布上可以发现,随着润滑油掺混比例的增加,颗粒物的团聚程度变高,这就意味着润滑油消耗越多,颗粒物的排放就越多,粒径越大。By adding a small amount of lubricating oil to diesel oil to enlarge the influence of lubricating oil on diesel particulate emissions, respectively, to the quality of fuel particle size and morphology were observed and analyzed using the fuel quality analyzer and scanning electron microscope. The results show that with the increase of oil content, the cetane value, the content of aromatic hydrocarbon and T90 also show an upward trend, which leads to the increase of fine particles. It is found from the morphology of particle size and distribution, with the increase of oil blending ratio, agglomeration of particles becomes higher, which means more consumption of lubricating oil, more particulate matter emission and larger particle size.
