利用车载测试系统,对混合动力客车及常规客车进行了整车排放测试,分析了混合动力客车在各典型行驶工况下的排放特征和车辆排放率随行驶力的变化关系.试验结果表明,混合动力车及常规车怠速工况时污染物排放贡献率最低,加速工况时污染物排放贡献率总体最高;常规车各污染物排放率随行驶力变化呈先下降后升高的趋势;混合动力车因其复杂的工作模式而导致复杂的变化趋势.该混合动力客车节能环保性能良好,比较适合在我国城市运行,但仍须加强怠速及加速工况的排放控制.

By using on-board test system, vehicle emission test on hybrid electric bus and conventional bus is conducted to analyze the emission features of hybrid electric bus in typical driving conditions and the relationship between vehicle emission rate and driving power. The test results show that for both hybrid electric bus and conven-tional bus, the contribution rate of pollutant emission is lowest in idle mode and is highest in acceleration mode. With the increase of driving power, the emission rates of all pollutants from conventional vehicles have a changing trend of downward first and then upward, but for hybrid electric vehicles, the changing trend of emission rate is rather complicated due to its complex working mode. The results also indicate that the hybrid electric bus mentioned has a good performance in both energy saving and environmental protection, and is relatively suitable for operating in the cities in China, but it is still a must to strengthen emission control in idle and acceleration modes.
