尾气后处理装置(EGR)的采用使柴油机油中的烟炱含量明显增加,对油品的烟炱分散和抗烟炱磨损等性能要求更加苛刻.通过四球试验和SRV缸套磨损试验考察几种添加剂单剂及其相互复配后在柴油机油中的抗烟炱磨损性能,筛选出较好的抗烟炱磨损评价方法和最佳的添加剂配方组成.结果表明:酸性磷酸酯铵盐与氨基甲酸酯复配可明显改善柴油机油的抗烟炱磨损性能;缸套磨损试验更适用于评价柴油机油的抗烟炱磨损性能.S R V

@@@@The soot content is increased significantly in diesel engine oil by using the exhaust gas recirculation(EGR), and the demands for the soot dispersion and anti-wear by soot performances of diesel engine oil are much more rigor-ous. Through the four ball test and SRV cylinder liner wear test on several additives single agent and compound with each other in diesel engine oil,the anti-wear by soot performance was investigated,and the better anti-wear by soot evaluation method and the best formula of additives were screen out. The results show that acid phosphate compound with ammonium carbamate can obviously improve the anti-wear by soot performance of diesel engine oil;and the SRV cylinder liner wear test is more suitable for the evaluation anti-wear by soot performance of diesel engine oil.
