| 摘 要： | 在实际道路行驶中测量了香港地区的汽车排放水平。选择了４部有代表性的车辆，两部汽油车，分别为无催化转换器和有催化转换器；两部柴油车，分别为轻型车和双层公共汽车。在车辆上安装了一套废气排放实时测量系统，可以在汽车行驶中连续测量汽车的瞬时气体排放和哈特里奇（Ｈａｒｔｒｉｄｇｅ）烟度、空燃比、发动机转速、汽车行驶速度、油耗率等。利用多次测得的以上数据，把瞬态排放值经过积分得到了平均的汽车排放因子［ｇ／ｋｍ或者ｇ／（ｋｇｆｕｅｌ）］。分析了平均车速和汽车载重量对平均排放因子的影响。

| Abstract: | In this paper,the emission factors of four motor vehicles in Hong Kong are developed based on the on road emissions measurement.An exhaust gas measurement system is set up and used in the on road tests,which enables the direct and continuous determination of the exhaust emissions from vehicles running on the road.Using this system the instantaneous concentrations of exhaust gases,smoke intensity,air fuel ratio,engine speed,vehicle speed,fuel consumption rate,etc,were recorded during the tests under realistic road conditions.The instantaneous emissions are integrated over a number of driving segments for obtaining the emission factors,and the effects of average speed of each segment and pay load were studied. |
