【摘要】 为研究IVE模型在国内的适应性,利用车载排放检测仪器OBS-2200,在天津市典型道路上对随机获得的74辆不同类型车辆进行测试,并利用IVE模型附带模版对车载排放数据进行处理,得出了天津市不同技术类型车辆的排放特性曲线。通过与模型标准排放特性曲线对比,得出了该模型对我国城市车辆排放CO2的排放特性曲线符合性较好,对HC排放符合性较差等一系列结论。更多还原

【Abstract】 Using a set of portable emission measurement system-OBS-2200,74 vehicles of different types are tested on the representative road in Tianjin to get the raw data for application of international vehicle emission （IVE） model,which is processed with the software enclosed by IVE.And the actual emission variation with VSP（vehicle specific power） Bin for different vehicles are obtained for comparison with the normal emission curve in the IVE model.In the end,comparing with standard emission characteristic curve in IVE model,conclusions of application for China of IVE model are given in this paper, which are suitable for CO₂-emission characteristic curve preferably,but is suitable for HC-emission characteristic curve badly.更多还原
