摘　　要：简述了近年来二甲醚发动机的发展动态,针对二甲醚自润滑性能差等特点,分析了二甲醚对传统柴油机喷油泵造成磨损与泄漏的问题。依据化工领域广泛使用的隔膜泵的技术特点,提出用隔膜泵替代传统柴油机喷油泵的设想,并探讨了可行性。The development of DME engine has been resumed in recent years.According to DME＇s poor self-lubricate and other properties,the problems of abrasion and leak in traditional diesel jerk pump,which are caused by DME,have been analyzed.Diaphragm pumps are used widely in chemical industry field,on base of which,the assumption that diaphragm pump replaces traditional diesel jerk pump has been proposed and the feasibility has been researched.
