插电式混合动力汽车污染物排放研究

Investigation of Plug-in Hybrid Vehicle Exhaust Emission

对一辆插电式混合动力汽车分别在常温和低温环境下进行污染物排放测试.通过试验结果,分析低温环境对插电式混合动力汽车污染物排放的影响,得到如下结论:在低温下,插电式混合动力汽车污染物排放成倍增加,排放污染物主要来自于低速工况.驾驶插电式混合动力车型在冬季短途出行尽量使用纯电模式是改善城市空气质量及减少雾霾的有效手段.

This paper conduct pollutant emission tests on a plug-in hybrid electric vehicle in normal and low temperature environments.By analyzing the influence of low temperature environment on the plug-in hybrid vehicle exhaust emission from the test result,the following conclusions are obtained:the exhaust emissions result of plug-in hybrid electric vehicles increases several time at low temperature,and the emission mainly comes from the low-speed cycle.Using pure electric mode as much as possible when driving plug-in hybrid vehicle for short-distance trip in winter is an effective means to improve urban air quality and reduce smog.
