不同积分方法在摩托车国四排放试验过程中的应用研究

Research on Effects of Different Integration Methods Application in China National Stage-IV Motorcycle Emission Test

摩托车国四排放试验过程中,各排气污染物排放量计算需要的试验过程中的行驶距离。本文旨在研究车速对时间积分法求解行驶距离,重点研究了矩形积分法和梯形积分法对试验结果的影响。

In the process of China national stage-IV motorcycle emission test, the distance traveled during the test is needed during computing the amount of each pollutant. This paper aims to research vehicle speed integral methods, the in？uence of rectangle integration and trapezoidal integration on the test results is mainly studied.
