| 摘 要： | 模拟分析了COPERTⅣ模型中不同污染物排放因子计算结果对主要输入参数的敏感性.以COPERTⅣ模型为平台,以重型柴油货车为研究对象,分别模拟了不同行驶速度、排放标准、燃料含硫率、累计行驶里程、车辆负载、道路类型、道路坡度、是否执行I/M制度等情景下的排放因子,对比分析了不同参数对CO、VOC、NOx、PM、SO2等污染物排放因子的影响,得出以下主要结论:0~45 km/h为速度变化的敏感范围,国2及国4排放阶段相较于前一阶段排放因子有较大幅度下降等.

| Abstract: | The sensitivity of different pollutant emission factors to the main input parameters in the COPERTⅣ model was simulated and analyzed.Based on the model COPERTⅣ,the heavy-duty diesel trucks were used to simulate the emission factors with different input parameters such as driving speed,emission standard,fuel sulfur content,accumulated mileage,vehicle load,road type,road slope and whether to implement the I/M system,and thenthe influence of different input parameters on pollutant emission factors such as CO,VOC,NOx,PM and SO2 was analyzed and compared.Theresults show that,0~45 km/his the sensitive range of driving speed change,the emission factors for phase 2 and 4 emission standard are much lower than those of the previous stage. |
