汽车废机油预处理前后理化指标变化规律研究

Study on the Change Regularity of Physical and Chemical Indicators of Used Engine Oil Before and After Treatment

本文选取了某汽车4S店和某长途客车运输公司两种类型的废机油。针对废机油预处理前后的粘度、机械杂质、密度、开口闪点、抗磨性等理化指标进行了研究。结果表明本文所用的预处理方法明显有效,经过预处理废机油的各项指标得到明显改善。

This paper selected two types of used engine oil（a automobile 4S shop and a Long-distance bus transport company）.Compare to before and after treatment of used engine oil,we studied used engine oil viscosity,mechanical impurities,density,open flash point,abrasion resistance and some other physical and chemical indicators.The results showed that pretreatment method used in this article clearly effective,the indicators are improved.
