摘　　要：将聚甲氧基二甲醚(PODE)/柴油按照1:9的体积比进行混合,调整柴油机供油提前角,分别在16°CA、18°CA和20°CA时进行排放测试。结果表明,随着供油的提前,燃用PODE/柴油混合燃料的柴油在CO、HC的排放上有较好的改善作用,然而会增加NOx的排放;燃用PODE/柴油混合燃料时,颗粒物(PM)的总数量浓度和总体积浓度都有所下降,而提前供油会增加颗粒物的总数量浓度,降低总体积浓度,且PM粒径分布朝小粒径方向偏移。PODE/diesel was mixed in the volume ratio of 1 : 9 to adjust the advance angle of diesel oil supply,and the emissions were tested at 16 ° CA, 18 ° CA and 20 ° CA respectively. The results show that diesel fuel with PODE/diesel blends can improve the emission of CO and HC with the advance of fuel supply, but it can increase the emission of NO x. When using PODE/diesel blends, particulate matter( PM) decreased both in the total concentration and in the total volume, while advance oil supply increased the total concentration of the particulate matter, decreased the total volume concentration, and the PM particle size distribution shifted toward the smaller particle size.
