| 中文摘要: |
| 车辆实际道路排放状态与运动特征、运行工况关系密切，本文以混凝土运输车为对象，基于OBD和远程监测技术，研究其实际道路行驶条件下的车辆运动和排放特征。结果显示：混凝土运输车在实际运行过程中活动特征呈现明显规律性，且NOx排放浓度随着车辆运行车速的增加具有降低趋势，提升车辆通行效率对改善车辆排放水平具有积极作用。 |
| 英文摘要: |
| The real drive emission status of vehicles is closely related to their activity characteristics and driving conditions. This article takes concrete transport vehicles as the object, and based on OBD and remote monitoring technology, studies their vehicle activity and emission characteristics under real driving conditions. The results show that the activity characteristics of concrete transport vehicles exhibit obvious regularity during real operation, and the NOx emission concentration shows a decreasing trend with the increase of vehicle speed. Improving vehicle traffic efficiency has a positive effect on improving vehicle emission. |
