摘要
在具有双喷射系统的压燃式发动机中 ,用一个喷射系统喷射乙醇 (C2 H5OH)作为主要燃料 ,另一个喷射柴油作为引燃燃料 ,进行不同负荷下的性能和排放试验。试验结果表明 ,用柴油引燃的压燃式乙醇发动机与原柴油机相比 ,烟度最大可下降 5 6 % ,NOx 排放量可下降 5 0 %～ 6 8% ,但 CO和 THC排放量上升较多。
The performance, fuel consumption and exhaust emission of a direct injection compression ignition (CI) engine with dual injection system at constant and varied load conditions were measured. The engine used alcohol as main fuel sprayed by an injecting system and diesel oil as ignition fuel injected by another injection system. The test results showed that the ethanol engine with diesel oil as igniting fuel had opacity smoke decreased by 56%, NOx emission decreased by 50%-68%, and CO and THC emissions increased significantly compared with those from a conventional diesel engine.
