摘要
将柴油机增压技术、废气再循环技术、共轨式燃料喷射技术应用于二甲醚 (DME)发动机 ,探讨了在各种技术条件下发动机的排放性能、动力性和经济性。结果表明 ,共轨式燃料系统有利于解决DME燃料的可压缩性和泄漏问题 ;进气增压技术有利于改善燃烧 ,降低排放和能量消耗率 ;废气再循环技术可以有效地降低NOx 排放 ;进气增压和适度的废气再循环率相结合 ,可以同时降低排放和改善能量消耗率 。
In this paper,the advanced technologies in diesel engine,including supercharging,EGR and common rail fuel supply were applied to dimethyl ether engine The engine performance was investigated in various operating conditions The results show that common rail fuel supply system can solve the problems of compressibility and leak of DME fuel,supercharging can improve combustion,exhaust emission and energy consumption of DME engine and EGR can reduce NO x emission obviously while the combination of supercharging and EGR is beneficial to both low fuel consumption and meeting ultra low emission regulation for DME engine
