| 摘 要： | 利用颗粒物数量测试仪器ELPI对瞬态循环下的汽油车和天然气汽车的颗粒物排放进行了测量研究,研究结果表明:汽油车排放的颗粒物明显多于天然气汽车,两种燃料车辆排放的颗粒物中粒径小于70nm的颗粒物均占绝对优势,占总排放量的80%～90%;大于200nm的颗粒物在总排放颗粒物中占的比例非常小;颗粒物数量排放浓度与车辆速度基本成正比例关系,颗粒物数量排放随速度的增加而增加;在车辆速度大于70km/h后,颗粒物数量排放随车速急剧增加.

| Abstract: | The measurements of the particulate emission from gasoline and compressed natural gas(CNG) vehicles under transient cycles are performed using electrical low-pressure impactor(ELPI).The results show that the number of particulates emitted from gasoline vehicle is greater than that from CNG vehicle.And in the emission from both gasoline and CNG vehicles,the particulates with diameter smaller than 70nm are dominant,accounting for more than 80%~90% of the total,while the particulates greater than 200nm account... |
