摘要
采集了北京市200辆国Ⅴ在用车的IUPR信息,通过对IUPR信息相关数据分析发现,各监测项的IUPR均值均满足国Ⅴ限值要求,但有部分车辆的IUPR值存在不符合限值要求的情况。通过对NEDC工况与典型路况下的IUPR功能试验发现,NEDC工况下IUPR值满足限值要求,而实际道路工况下(尤其拥堵路况)会造成各监测项的IUPR值不能满足限值要求,因此,建议根据中国的实际道路交通情况对监测条件进行修正。
In this research, IUPR information of 200 China V vehicles in Beijing is collected. The analysis on the IUPR data shows that the average IUPR of the monitored items complies with China V limit requirement, whereas that of some vehicle doesn＇t comply with such limit. The IUPR functional test under the NEDC and the real road condition show that the IUPR works well under the NEDC, the IUPR can not comply with limit requirement in real road conditions （especially congested condition）, therefore a revision to monitoring condition according to real road condition in China is recommended.
