| 摘 要： | 介绍了IVE尾气排放模型并与MOBILE模型进行了比较分析。使用GPS对上海市公交车多条运行线路进行了实时运行速度测量,得到上海公交车运行模式的BIN分布,对上海市CNG公交车和柴油公交车的尾气排放进行了模拟计算。结果表明使用CNG公交车代替柴油公交车后,NOX和PM的排放均有显著的降低,但采用不同技术的CNG公交车尾气排放仍有很大的差异,无催化转化和尾气再循环的CNG公交车的CO排放量远高于同类型柴油公交车的排放量。认为IVE模型的模拟结果具有较好的可靠性,其计算模式适用于我国机动车尾气排放清单分析的研究。

| Abstract: | The IVE (International Vehicle Emission) model is used in comparison with the commonly-used MOBILE model for evaluating exhaust emission of mass transit vehicles in Shanghai. Real time bus velocity is measured with GPS system and driving pattern of bus is calculated. Simulation and predict regarding diesel and CNG (compressed natural gas) bus indicate that CNG if replaces diesel can remarkably cut the emissions of both NOx and PM; however, application of catalyst devices and EGR is still important for CNG bus to reducing pollution according to the modeling of IVE. |
