摘要
为更有效控制机动车的实际道路排放,轻型车国六法规中规定了实际行驶排放(RDE)的实验要求。由于没有固定的驾驶循环,道路交通状况和驾驶员的驾驶行为对RDE实验结果有重要影响,进而影响对车辆实际排放的客观评价。本文选择典型车辆研究了不同驾驶行为对实际道路车辆排放的影响。实验结果表明:NO_x和PN排放量与车辆的动力学参数v·a_(pos_)[95]和RPA具有明显的相关性,而CO排放量与车辆动力学参数之间的相关性不明显。市区工况下,NO_x排放量随动力学参数v·a_(pos_)[95]的增大而增大,而PN排放量随动力学参数RPA的增加而增加;在市郊和高速工况下,NO_x排放量与动力学参数RPA有较强的相关性,而PN排放量则与动力学参数v·a_(pos_)[95]和RPA都有较强的相关性。
For more effectively controlling the emissions in real road driving,China-VI regulation for light vehicles provisions the requirements for real driving emission（ RDE） test. Because there is no fixed driving cycle,so the road traffic conditions and the driving behavior of drivers have significant effects on the results of RDE test,and hence on the objective evaluation of real vehicle emissions. In this paper,a typical vehicle is chosen to study the effects of different driving behaviors on real road vehicle emissions. The results show that the emissions of NOx and PN have obvious correlations with vehicle dynamics parameters v·apos〈/sub〉[95]and RPA,while CO emission has not. Under urban condition,NOx emission increases with the rise of v·apos〈/sub〉[95],while PN emission rises with the increase of RPA. Under suburban and high speed driving conditions NOx emission has rather strong correlation with RPA,while PN emission has strong correlation with both v·apos〈/sub〉[95]and RPA.
