中文摘要	对3辆缸内直喷(GDI)汽车和1辆进气道燃油喷射(PFI)汽车进行了试验研究,在NEDC循环上采用PMP方法测量微粒质量排放和微粒数量排放,用DMS500型快速微粒分析仪测量微粒瞬态数量排放和粒径分布。结果表明:4辆试验车的微粒质量排放均达到欧Ⅵ法规要求,但GDI汽车的微粒排放远超出法规限值;GDI汽车和PFI汽车在冷起动暖机阶段均有大量微粒生成,GDI汽车在暖机后的瞬态工况会有明显的微粒排放;GDI汽车核态微粒峰值粒径约为18nm,而作为数量排放主要形态的积聚态峰值粒径约为80nm;PFI汽车的积聚态峰值粒径约为60nm,而作为其数量排放主要形态的核态微粒峰值粒径约为12nm。; An experimental study on the particulate emissions of three GDI cars and one PFI car is conducted with NEDC cycle. The particle mass emission and particle number emission are measured by using PMP method while the transient particle number emission and particle size distribution are measured with DMS500 fast particle analyzer. The results show that the particle mass emissions from four cars all meet the requirements of Euro VI regulation,but the particle number emissions from GDI cars far exceed the regulation limit value. There is a large amount of particulates emitted from both GDI and PFI cars during cold start warm-up stage,and for GDI car there still exists apparent particulate emission even after the engine has warmed up. The peak diameter of nucleation particulates from GDI car is about 18 nm,and the majority of particulates is accumulation ones with a peak diameter of about 80nm; while for PFI car,the peak diameter of accumulation particulates is around 60 nm,and that of nucleation particulates,the majority of particulates,is around 12 nm.
