摘　　要：通过对燃用柴油醇发动机排气污染物的试验研究,探讨了其排气污染物的形成原因,分析了排放物随发动机转速及负荷的变化规律。研究结果表明:柴油醇可以有效地降低柴油机的排气污染物,尤其是碳烟排放。在大负荷下,HC和CO排放浓度降低,但发动机工作粗暴,NOx排放较燃用柴油高。The formation of pollutant from diesohol engine is discussed based on measure and analysis of emissions. The rule of emissions along with engine rotational speed and load is discussed. The result shows that the pollutant was reduced effectively, especially to soot emission. On full load, the emissions of HC and CO were reduced, but the emission of NOx was increased and the engine worked unsteadily.
