混合动力客车排放测试及分析

Hybrid Bus Emissions Measurement and Analysis

为了验证混合动力车辆在节能和环保方面相对于传统车辆是否有明显的优势,文章采用车载排放设备对混合动力客车和传统客车进行了排放对比测试试验,结果表明,混合动力车辆的电量储能装置优化了发动机的工作范围,使发动机始终工作在最优状态,从而减少了车辆污染物的排放。指出混合动力车辆可以减少污染物的排放,具有很好的环保效应,能够明显改善城市的环境状况。

In order to verify whether hybrid vehicles have obvious superiority in the aspects of energy-saving and environmental protection compared with conventional vehicles, contrast measurements on the exhaust emissions between hybrid and conventional bus are made by Portable Emission Measurement System （PEMS）. The experiment results validate that hybrid vehicles can greatly reduce exhaust emissions because the electricity storage devices optimize the engine＇ s working range. With less pollutant and exhaust emission, hybrid vehicles are much more environment-friendly and can improve the city＇ s environmental conditions greatly.
