| 摘 要： | 主要对比了缸内直喷发动机与进气道发动机的不同的工作原理。由于二者不同的工作原理,从点火时刻、喷油时刻、空燃比、EGR率等方面介绍了上述因素对发动机超细颗粒物排放(主要针对粒径小于100 nm)的影响。

| Abstract: | The different working principles of GDI gasoline engine and PFI gasoline engine were compared. Due to the different working principle, in terms of ignition timing, injection timing, air-fuel ratio, EGR rate, the impacts of these factors on the engine emissions of ultrafine particles （especially on the particle size less than 100 nm） were described. |

| Keywords: | GDI Gasoline engine Uhrafine particles |
