Abstract The emission characteristics of particulate mass, particle number, particle size distribution and the composition of soluble organic fractions from a stoichiometric gasoline direct injection (GDI) vehicle certified to China V emission standard over different test cycles i.e., New European driving cycle (NEDC), worldwide harmonized light vehicle test cycle (WLTC) and USA federal test procedure-75 (FTP-75)) were investigated. The results showed that particle size distribution over NEDC, FTP-75, and WLTC was basically the same, with a logarithmic bimodal distribution, when the peaks occurred at 9nm and 60nm; 5.6~23nm particulate matter emissions occupy 43.1%~57.7% of the 5.6~560nm particulate matter. Compared with NEDC, particulate mass, 23nm~2.5μm solid particle number and 5.6~560nm particle number emissions of FTP-75 and WLTC increased due to their higher deceleration and acceleration ratios and the stronger transient performance; soluble organic fraction accounted for 20.5%~27.9% of the particulate matter emitted from gasoline direct injection vehicle. The soluble organic fraction mainly contained C16 and C18 fatty acids, C20~C29 alkane diameter and high molecular weight polycyclic aromatic hydrocarbons with 5 rings or more, while different test cycles showed diverse impact on SOF emission and its components, FTP-75 and WLTC with stronger transient performance revealed higher proportion of PAHs.

Key words： GDI vehicles particle mass particle number size distribution soluble organic fraction
