Study on the Relationship Between Chemical Composition and Anti-Wear Performance of Internal Combustion Engine Oil
To provide a theoretical basis and practical guidance for improving the performance of engine oil,this paper discusses the relationship between the chemical composition of internal combustion engine oil(hereinafter referred to as"engine oil")and its anti-wear performance,in order The chemical composition of engine oil and the types and functions of additives are summarized.By means of chromatographic analysis,spectral analysis and other scientific technological means,the chemical composition of engine oil is quantitatively and qualitatively analyzed.And the influence of the chemical composition of engine oil on its anti-wear performance is further studied and analyzed.On the one hand,the effect of the chemical structure of base oil on lubricity and anti-wear performance is explored.the key factors and influencing mechanisms of the anti-wear performance are clarified,which provides a scientific basis for the formula and performance optimization of engine oil.On the other hand,the mechanism of sulfur,phosphorus,nitrogen and other elements in anti-wear additive is analyzed,as the same time,the synergy and antagonism effects between the additives were expounded.Based on this,we can further explore the development and application of new additives in the future.
