提高低硫柴油润滑性能的措施

减少燃料油硫含量是降低尾气污染物排放量保护环境的重要措施,许多国家和地区的柴油硫含量已经降低到50μg/g以下。随着柴油硫含量的降低,其润滑性也变差。低硫柴油增大了发动机磨损,甚至使发动机发生失效。分析了解决低硫柴油润滑性的途径,重点介绍了利用三种类型添加剂对柴油润滑性影响的实验过程和分析结果,指出加入添加剂是提高柴油润滑性的有效方法。

How to Improve Lubricating Properties of Low-sulfur Diesel Oil

Lowering sulfur contents in fuel oil,which is al-ready below50μg /g in many countries and regions,is an important measure to reduce pollutant emission in end gas and to protect environment.The lubricating properties of diesel oil get poorer along with the reduction of sulfur content.Low-sulfur diesel oil can enlarge the attrition rate of engines and even can result in engines out of function.This paper analyzes the ways to improve the lu-bricating properties,introduces the experimental process and results of the impacts of three additives on lubricat-ing properties,and points out that adding additives is an effective way to enhance the lubricating properties of diesel oil.
