研究了柴油轿车燃用生物柴油时排气颗粒的理化特性,所用燃油分别为纯柴油、生物柴油掺混比例为10％的B10燃油.进行了NEDC整车循环试验,测取了柴油轿车的排气颗粒质量、颗粒数量及粒径分布、颗粒多环芳烃的排放特性.结果表明:与纯柴油相比,该车燃用B10燃油的排气颗粒质量有所降低,但颗粒总数量有所增加.燃用生物柴油后,排气颗粒的粒径分布有整体向小粒径方向移动的趋势,较小粒径的核态颗粒数量有所增加,较大粒径的聚集态颗粒有所下降.在EUDC市郊循环下,该移动趋势更为明显.与纯柴油相比,该车燃用B10燃油的排气颗粒低环数PAHs有所增加,高环数的颗粒PAHs排放降幅明显.柴油轿车燃用生物柴油后,排气颗粒中多环芳烃BEQ毒性有所下降.
