车用发动机磨合油研究

Study on the Engine Running-in Oil Applied Ultra-dispersed Diamond

超精细金刚石（ＵＤＤ）粉是利用爆炸法人工合成的具有实用价值的纳米材料，它具有一系列特殊的物理及化学特性，本文针对车用内燃机磨合特点，并利用ＵＤＤ的特殊性能，研制一种高效专用内燃机磨合油。

The ultra-dispersed diamond(UDD) powders synthesized by the detonation of explosives with negative oxygen balance are new nano- materils with practical value. They have a series of special physical and chemical properties. Focus on the characteristics of engine running-in, concentrated and special oil of engine running-in was developed by UDD nano-powders in this paper.
