摘      要：Diesel engine technology innovation causes excessive soot accumulated in engine *** to its detrimental effect on lubricant and diesel engine,improving the dispersibility of engine oil to restrain soot aggregation efficiently is the key technique for *** this study,the aggregation of soot and interaction between dispersant and soot were investigated by molecular dynamic *** was found that the molecular interaction between the dispersant and the soot aggregation system had a significant influence on disrupting the soot ***-PIBSI was more beneficial to having more interaction sites with soot molecules,while the mono-PIBSI with a high proportion of polar groups had stronger interaction with soot *** to the simulation result,suggestions for use of additives were *** black dispersancy test was exploited to verify the dispersion effect of different dispersants on carbon *** results indicate that mono-PIBSI and bis-PIBSI added at suitable mixture ratio to lubricant could perform good dispersion ability.
