| 摘 要： | 随着经济的发展，机动车排放已成为大气颗粒物的重要来源，能够影响人类健康和气候变化.本研究通过整车转鼓实验对国V缸内直喷（GDI）汽油车的颗粒物排放水平及化学组成进行了研究，并探究了汽油车颗粒物排放的影响因素.研究结果表明，我国GDI汽油车的PM、OC、EC排放因子分别为（43.4±16.2）、（11.0±3.5）及（20.5±8.1）mg·kg-1，其中EC的排放显著高于同类研究.为探索导致颗粒物排放区别的影响因素，本研究探讨了燃油类型、启动方式和循环设定对汽油车颗粒物排放的影响.结果表明，燃油类型（添加体积分数10%的乙醇与纯汽油）对颗粒物排放影响不大.冷启动会排放更多的颗粒物.同时，循环方式也会影响颗粒物排放，中国工况循环（CLTC）会排放比全球测试循环（WLTC）更多的颗粒物，这可能与我国更多的缓加速情况相关.
