摘　　要： 应用美国Sensors公司生产的SEMTECH-DS车载排放测试仪,测试了4辆汽油小轿车在深圳市两种不同类型的典型道路工况下的排放污染物(CO、HC、NOx)的排放特征,对测试数据进行深入的分析,结果表明:车辆的各种排放因子随速度的降低而增加,车速低于10km.h-1的排放污染物急剧增加;车辆在不同特征道路行驶的CO与HC平均排放因子(g.km-1)相差显著,CO与HC的平均排放因子是快速路的2倍以上。 In the paper experiments were done to four gasoline cars on two typical road conditions in Shenzhen for emission characteristics of CO, HC and NOx with SEMTECH-DS manufactured by Sensors Company in USA. Through analysis on the experimental data it is indicated that all emission factors increase with the vehicle speed down, and emission is sharply up when vehicle speed is lower than 10km · h^-l; average emission factors of CO and HC when car running in different characteristic road varies apparently, and average emission factors of CO and HC for car running in secondary city main roads is above two times than those in city main roads.
