| 摘 要： | 通过对258辆大型城市客车进行加速模拟工况排放测试，研究了城市客车的排放特性，比较了压缩天然气(CNG)车辆与汽油车辆的排放特性，分析了车辆车龄与排放的关系、发动机燃油供给方式与排放的关系，以及车辆总质量与排放的关系。研究结果表明：燃用CNG的车辆其CO、NOx排放较汽油低许多，尤其是CO，但HC排放较汽油高；电喷车辆的CO、NOx排放比化油器车低，但HC排放值高于化油器车；车龄增长，车辆的CO、NOx排放值增大，但HC变化不明显；车辆总质量增加，排放呈下降趋势。

| Abstract: | The paper studied the exhaust emission characteristics of big city bus by testing 258 big city buses under ASM steady mode. It was compared the exhaust emission test results of CNG bus with that of gasoline bus. And it was analyzed the relationship between the emission level and vehicle age, emission level and fuel supply system of engine, and emission level and vehicle total mass. The results showed that CO and HC emission, especially CO of CNG bus are lower much than that of gasoline bus, but not HC, which is same as that electronic fuel injection bus compared with gasoline engine. The CO and HC emission increase quickly with the increase of vehicle age, but not HC. The exhaust emission of big city bus decreases with the increase of vehicle total mass. |
