| 摘 要： | 针对定量评价机动车在特定运行状况下排放状况的问题，采用轻型车在OEM-2100的基础上搭建了车载排放测试试验平台进行实际道路试验. 分析了机动车在不同运行工况模式下3种排放污染物的差异；分别分析了速度和加速度对机动车3种排放污染物质量排放率的影响，并获得了速度和加速度联合分布下3种污染物的排放特征. 研究结果表明加速工况下的排放值要明显高于其他工况，巡航次之，其次是怠速和减速；速度和加速度对车辆排放都有较大的影响，轻型车的行驶速度控制在30~50 km·h-1范围内中速行驶，加速度小于等于0.5 m·s-2时，可达到最佳的排放性能.

| Abstract: | In order to accurately reflect the vehicle emissions change with operation condition, vehicle emission test experiment platform is established for the actual road test based on light-duty vehicle by OEM-2100. The difference of emission pollutants under different operation modes and the influence of three kinds of motor vehicles emission pollutants discharge rate caused by velocity and acceleration were analyzed. Three kinds of pollutants emission characteristics under the joint distribution of velocity and acceleration were given. The results show that emission value under accelerated condition is significantly higher than under other conditions, and cruise takes second place, followed by idle speed and slow. What's more, when the speed is in 30~50 km·h-1, the acceleration is less than or equal 0.5 m·s-2, it can achieve the best emissions performance. |
