摘　　要：现代柴油机技术清洁了排放 ,却使进入机油中的碳烟微粒大量增加。本文研究报道了悬浮碳烟微粒对在用柴油机油粘度的影响 :粘度随碳烟浓度提高而增大 ,二者符合Eilers和Kreiger-Dougherty粘度方程 ,分散剂能阻止碳烟微粒发生聚结 ,进而降低相对粘度 。Modern diesel engine technology cleans diesel exhausts, but makes the engine oil sooty Studied and reported in this paper was the effect of suspended soot particle on the viscosity of in use diesel engine oil Results displayed that the viscosity increases with soot particle concentration increasing and their relationship is in good accordance with Eilers equation or Kreiger-Dougherty equation Dispersants can prevent soot particle aggregation or agglomeration and thus decrease relative viscosity, with the performances of basic dispersants far better than those of neutral dispersants
