摘　　要：采用一套车载排放检测装置,对上海城市道路、高速道路进行实际道路排放测试.行驶工况对车辆污染物排放影响明显,加速及高速匀速段,污染物浓度对排放速率起主要影响;减速段,排气量对排放速率的影响程度高于污染物浓度.高速道路行驶,CO、NO的排放速率主要受其浓度影响,HC的排放速率受排气量的影响较大;CO、HC和NO污染物实测排放因子分别为1.47、0.02和0.08 g/km.A Portable Emission Measurement System has been developed,which enables testing the light-duty vehicle emissions from urban roads and highways in Shanghai. Driving conditions have an obvious impact on vehicle emissions. In acceleration and regular high-speed stage,concentration plays a major impact on emission rate; in deceleration stage,the impact of displacement on emission rate is stronger than that of the concentration; on highway,CO and NO are majorly affected by concentration and HC is mainly affected by displacement. Emission factors of CO、HC,and NO are 1. 47,0. 02,and 0. 08 g / km,respectively.
