摘要：

本文针对汽油组分对GDI 汽油机一次颗粒物排放和二次颗粒物生成影响等国内外研究进展进行综述。已有研究表明：汽油中芳香烃体积分数增加，会使GDI 汽油机一次颗粒物、颗粒中多环芳香烃(PAH) 和排气中可挥发有机物(VOC) 增加，最终导致排气在大气中形成的二次颗粒物生成量增加；汽油机排气生成的二次颗粒物远高于其一次颗粒物，大气中二次颗粒物的主要成分即二次有机气溶胶(SOA) 生成量有相当一部分源自于汽油车排气中的VOC 和PAH，但汽油车排气在排气系统中的演变特性以及在大气中如何转化为SOA 的物理化学过程需要开展进一步的研究工作。

Abstract:

The impact of fuel composition on primary particulate emissions from GDI engines and subsequent formation of secondary particles in atmosphere has received global attention. This paper gives a comprehensive overview of the impact of fuel properties on primary and secondary particulate formation from GDI engines. It is shown that higher aromatics content in gasoline fuel results in higher particulate emissions, higher polycyclic aromatic hydrocarbons (PAH) in particles and higher volatile organic compounds (VOC) emissions as well as more secondary organic aerosol (SOA). The SOA formation, which mainly comes from VOC and PAH emissions, is much higher than primary particulate emissions from gasoline engines. However, the evolution characteristics of the emissions in tailpipe and the mechanisms of the SOA formation from gasoline engines in air have not been understood completely.
