轻型机动车尾气排放测试研究

Research on the light-duty vehicles emission test

通过在底盘测功机上进行轻型机动车的稳态负荷工况测试和瞬态负荷工况测试 ,进一步研究轻型机动车尾气排放污染物浓度、发动机输出功率、机动车行驶速度的相关性。并提出了通过计算排放变化率 /加速度比例系数来确定稳态工况与瞬态工况的相关关系的方法 ,这对于

According to the Steady\|State Load Test and the Transient Load Test performed on the chassis dynamometer, the relationship between light\|duty vehicles emission pollutants concentration, motor output horsepower and vehicle tracing speed were researched. It also propose the method to definite the relationship between the Steady\|Load Test & the Transient\|Load Test through the calculation of Emission Change Rate/Acceleration ratio coefficient, and it may be of great technical meaning to the I/M system.\;
