摘　　要：柴油深度脱硫导致柴油润滑性下降,为提高低硫柴油的润滑性,需在柴油中加入柴油润滑剂。利用四球磨损试验机建立了用来测量低硫柴油润滑性的试验方法,这个测量方法是具有简便、快速、费用低的特点,对不同质量的低硫柴油有较好的区分性和重复性。The lubricity of low sulfur diesel fuels tends to be poor due to deep desulfurization. In order to improve the lubricity of low sulphur diesel fuels, additives should be used on diesel fuels. A new test based on four ball wearing machine method has been developed to measure the lubricity of low sulfur diesel fuels. This measuring method is fast, convenient and low cost. A better distinction and repeatability are achieved for different quality level of diesel fuels.
