摘要
通过研究混合动力工程开发样车(Mule)与传统车在NEDC循环工况下的排放,发现Mule车相比较传统车排放不降反升,说明如果混合动力汽车没有经过相关标定优化,其控制策略会对整车排放产生消极影响。改进后的产品样车(OTS)在排放方面远远好于Mule车,除了NOx排放稍稍高于传统车外,HC和CO排放均低于传统车。
The emissions of Mule car and conventional car under NEDC （New European Driving Cycle） cycle conditions were researched, and it was found that the emission of Mule car was higher than that of conventional car, which showed that the non-optimized control strategy had the negative influence on the emission. The emission of OTS car except NOx emission was far better than that of Mule car, that was to say, the HC and CO emissions of OTS car were lower those of Mule car.
