在一台单缸发动机上,通过进气道预喷正庚烷和上止点前缸内直喷异辛烷,对双燃料分层充量压缩燃烧(Stratified Charge Compression Ignition,SCCI)进行了试验研究.通过进气道预喷的正庚烷在进气行程形成均匀混合气并在上止点前发生两阶段反应,触发缸内直喷的异辛烷着火与燃烧,整个燃烧过程为分阶段燃烧,分析了不同负荷及预混合率时的燃烧与排放特性.结果表明:最大压力升高率为0.87 MPa/(°)时,最大平均指示压力(I MEP)可达到0.73 MPa,说明SCCI可以扩展运行负荷.预喷燃油量最大时的工况点,其NOx排放值较高;预喷正庚烷燃空当量比一定时,增加负荷,可以减小CO和THC的排放.
