浅谈烟炱对柴油机油规格的影响及解决策略

文章通过对烟炱定义及其危害的阐述,说明解决烟炱问题的重要性。通过详细分析烟炱对柴油机油规格影响,阐明解决烟炱问题的迫切性。从烟炱产生的机理出发,仅从润滑油角度考虑,需要提高柴油机油的烟炱分散性能。通过对影响柴油机油烟炱分散性能的基础油、无灰分散剂、黏度指数改进剂的资料总结,给出了解决烟炱问题需要引入Ⅱ、Ⅲ、Ⅳ类基础油,高分子量的无灰分散剂以及具有分散性能的黏度指数改进剂,为高档柴油机油有效解决烟炱分散性能指出方向。

Study on Influences of Soot on Diesel Engine Oil Specification and Its Solution

The significance of coping with the soot formation in diesel engine is illustrated in this paper by elaborating on the soot’ s definition and its detriments.In addition,the desperate need for solving that problem is also raised after detailed analysis on the influences of soot on diesel engine oil specification.From the perspective of lubricating oil,it is described that the diesel engine oil’ s soot dispersing property should be concerned based on the soot forming mechanism.By summarizing on previous studies on influencing factors of base oil,ashless dispersant and VI improver on oil’ s soot dispersing property,it is suggested that the Group Ⅱ,Ⅲ,Ⅳ base oils,high molecular weight ashless dispersant,and VI improver with dispersing property should be introduced into the oil formulating system.This indicates an effective way to improve the soot dispersing property of high-quality diesel engine oil.
