| 摘 要： | 以柴油机为基础，以乙醇或甲醇作为预混合燃料，与喷入的柴油组成部分预混的复合燃烧，大幅度降低了发动机排气烟度，同时使氮氧化物排放得到一定改善，发动机的燃油消耗率优于原柴油机，而HC排放，尤其是在低负荷时有所增加，甲醇比乙醇具有降低烟度效果更好、氮氧化物降低更多和HC及CO排入增加较少的优越性。

| Abstract: | An experimental study of partial premixed compound combustion based on the diesel engine, with alcohols as premixed fuel was performed. The results showed that the exhaust smoke grade reduced greatly, the NO x emission deduced slightly, while the HC emission,specially at load condition increased. Methanol has more potential with greater lowering the smoke grade effect, more NO x reduction and less deterioration of HC emission effect. |
