| 摘 要： | 摘要：介绍了国内外二甲醚发动机燃料供给系统研究概况，包括油泵一油管一油嘴系统和共轨式燃料供给系统。二甲醚粘度低导致燃油供给系统磨损和泄漏是二甲醚发动机实用化面临的主要问题。针对可控预混合燃烧二甲醚发动机开发的一种用隔膜泵、磨损自补偿喷油器或者独立润滑喷油器构成的燃料喷射系统，有望从本质上解决上述问题，成为未来的一个发展方向。

| Abstract: | A survey of study on dimethyl ether engine fuel supply system at home and abroad is described,including pump-pipe-nozzle system and common-rail fuel supply system. The main trouble of practical application of dimethyl ether engine is wear and leakage problems in the fuel delivery system caused by low viscosity of dimethyl ether. For controllable premixed combustion of dimethyl ether engine,a fuel injection system is developed which is consisted of a diaphragm pump and a wear self-compensation nozzle or an independent lubrication nozzle. The system is expected to solve the above problems essentially and becomes a development direction for the future. |
