电加热催化器降低混合动力车辆排放的应用研究

Research on the Application of Electrically Heated Catalyst on Hybrid Vehicle Emission Reduction

为了应对全球越来越严苛的汽车排放法规,例如欧7、北美Tier3Bin30以及未来的国7,降低整车排放势在必行,而缩短发动机冷起动阶段的催化器起燃时间将是关键点。将着重研究电加热催化器在混合动力车辆上的应用开发,以达到更好的排放结果。

In order to satisfy the more and more stringent automotive emission regulations,such as Euro 7,US Tier3Bin30 and China 7 in the future,it is necessary to reduce the tailpipe emission of vehicle at cold start stage.The key is to shorten the light off time.Our study about the application development of the electrically heated catalyst(EHC) on a hybrid vehicle is introduced to get a better emission result.
