| 摘 要： | 根据对两种被测车型在天津市实际道路上行驶的总体平均参数和速度构成参数与 ECE- 15、FTP-75两种标准排放测试循环的比较 ,证明实测结果与目前所采用的标准测试循环的行驶特性有明显差异。为了得到能在实验室中真实评价机动车实际道路行驶排放特性的模拟测试循环 ,构造了能表征速度构成特性的准则数 ,并根据各种参数对机动车有害排放物影响的程度确定了不同的准则数相对误差阈值。试验结果表明 ,其设定值是合理的。

| Abstract: | Based on the comparisons of average parameters and speed composing parameters between real-road testing data in Tianjin and testing procedures of ECE-15,FTP-75, it is proved that there exist great distinctions between their properties.In order to obtain testing cycles which can be used to evaluate truly the amount of vehicle emissions in laboratory,it is reasonable to make criterion numbers which can denote the speed-composing property and to adopt different threshold according to their influences. |
