摘　　要：在一台单缸直喷式柴油机上分别燃用柴油、乙醇-柴油-生物柴油混合燃料,对不同掺烧比的乙醇-柴油-生物柴油混合燃料的排放特性进行了对比研究。试验结果表明,随着乙醇掺混比例的增大,燃用乙醇-柴油-生物柴油混合燃料的排放情况是:烟度排放大幅度降低,中高负荷下CO排放大幅度减少,HC排放量明显增加,NOx排放变化不大。An experimental study is made on the emission characteristics of a single-cylinder direct injection diesel engine with different proportions of diesel and ethanol-diesel-biodiesel. The results show that, while the mixed proportion of alcohol getting larger, the emission circumstances of diesel engine burning the ethanoldiesel-biodiesel blend fuel are that the smoke decreases significantly, that the CO emission decreases significantly at the medium and high loads, that the HC emission increases obviously, that the NOx emission does not basically change.
