| 摘 要： | 本文介绍了摩托车排放的WMTC（World-wide Motorcycle Test Cycle）测试循环，研究了WMTC测试循环的行驶特征及其与欧3排放测试循环的差异，并初步探讨了两种测试循环下摩托车排放因子的相关性。研究结果表明，较之欧3测试循环，WMTC怠速比例低，稳态工况少，瞬态工况比例高，对摩托车的排放控制技术提出了更为苛刻的要求。WMTC测试循环下和欧3测试循环下摩托车排放因子的相关性分散度较大，且规律性并不明显，表明两种排放因子的相关性有可能只存在于统计意义上。

| Abstract: | This paper presents a brief introduction of World-wide Motorcycle Test Cycle,usually known as WMTC.The difference of driving property between WMTC and EURO III,as well as the correlation of emission factor between WMTC and EURO III are also given.The results show that the idle proportion of WMTC is much lower than that of EURO III,whereas the acceleration and deceleration proportion of WMTC is much high,which means that the emission property of transient modes of a motorcycle is very critical to undertake WMTC test cycle.Also,it is proved that huge amounts of emission testing data on all kinds of motorcycles are absolutely necessary if the limitation values for WMTC are expected to be obtained through the emission correlation factor between WMTC and EURO III. |
