柴油清净剂清净性研究

Study on detergency of diesel-oil detergent

在XUD-9柴油发动机台架上,采用中国石油化工行业推荐标准SH/T—2005《柴油机喷嘴结焦试验方法》,研究清洁性不同的柴油对柴油机喷嘴结焦阻塞的影响。实验结果显示:加入有效的柴油清净剂,对柴油机喷嘴具有显著的清洁效果;我国车用柴油的清净性能与国外相比差距较大。

On the XUD -9 diesel test bed, using the recommendatory standard of China Petro- chemical Industry Association （CPIA） SH/T - 2005 《The Test Method of Diesel Injector Co- king》, the influence of different cleaning diesel on the injector coking of diesel engine are pres- ented. The results show that the adding effective diesel-oil detergents decrease the injector jam of diesel. There is biggish gap between internal and external of the diesel-oil＇s cleaning per- formance.
