摘　　要：利用车载排放测试系统(PEMS),对某小型载客汽车进行重庆市典型道路工况下的CO、HC、NOX排放测试。研究不同行驶模式、速度区间、路面情况对汽车排放的影响,并建立特定工况下排放因子与路面坡度之间的拟合模型。Using the Portable Emission Measurement Systems（PEMS）, the author tests CO, HC, NOXemissions to a small type of passenger vehicle under typical road conditions in Chongqing. He studies the influence of different driving modes, speed ranges and road conditions on the vehicle emission, and establishes the fitting model of the emission factors with the slope of road surface.
