【摘要】 为了准确地进行地区排放状况的定量分析,得到地区的排放因子和制定排放控制策略,以长春市区4种类型的道路作为研究对象,以道路实测数据为基础,分析得到4种类型道路的行驶工况特征值,继而研究各等级道路行驶工况下的排放因子以及速度对3种排放污染物的影响.结果反映出随着道路等级的降低机动车速度表现出递减的趋势,各等级道路行驶工况下速度对排放的影响表现出相近的规律.更多还原

【Abstract】 To analyze the situation of city’s pollution quantitatively and achieve the pollution-control strategy,four different graded roads in Changchun were investigated to get drive cycles of them on the basis of tested data.On the basis of analyzing the drive cycles of urban graded roads,the impact of vehicle emission factors and driving speed on three pollutants in the drive cycles of urban graded roads was studied.It is indicated that the speed of vehicle trends to be lower with the decreased grades of road,and the vehicle emission trends to be lower with the decreased speed.更多还原
