| Abstract: | The soot-dispersancy is required higher and higher with the upgrading of heavy-duty diesel engine oil.Results of the tests showed that base oils with different chemical group compositions have different effects on soot-dispersancy of oils,and alkane is the ideal composition.The study also revealed that viscosity index improvers and additives used in oils such as dispersants,detergents,anti-oxidants also have important impacts on soot-dispersancy of oils.It provides technical support for the development of h... |
