摘　　要：乳化燃油微爆能够促进燃油雾化和混合,影响其微爆性能的关键是乳化剂。文章采用机械搅拌加超声搅拌法制备了微乳化甲醇柴油,研究了乳化剂种类和含量对微乳化甲醇柴油稳定性和分散性的影响规律。研究结果表明:采用复合乳化剂和增加乳化剂含量均能提高微乳化甲醇柴油的分散性;增加乳化剂含量能够提高液滴微爆强度,推迟初次微爆时刻,减少液滴寿命,降低稳定阶段的液滴蒸发速率;当甲醇和乳化剂的质量比为10∶5和10∶8时,液滴微爆强度分别比甲醇和乳化剂质量比为10∶3时提高了34.3%和37.6%。The micro-explosion of emulsified fuel can promote fuel atomization and mixing,however the key to affect its micro-explosion characteristic is the emulsifier.Emulsified methanoldiesel was prepared by mechanical emulsification and phacoemulsification,to study the effect of emulsifier types and content on the stability and dispersion of micro emulsified methanol-diesel.The results show the dispersion of the micro emulsified methanol-diesel can be improved by using compound emulsifiers and increasing the emulsifier content;The increase of emulsifier content can improve the micro-explosion intensity,delay the initial time of micro-explosion,reduce the droplet life,and reduce the droplet evaporation rate in the stabilization stage;The micro-explosion intensity of methanol emulsifier content ratio of 10∶5 and 10∶8 was increased by 34.3%and 37.6%compared with methanol emulsifier content ratio of 10∶3 respectively.
