摘要
根据国Ⅵ轻型车排放标准中规定的实际道路排放测试规程,选定试验车在规定道路进行试验,用车载排放分析设备测量排放数据,用CO_(2)平均窗口法分析排放因子在不同路段的差异。结果表明:当加速度较小时,CO排放量在低速段随车速增加而增加,在高速段排放量基本为0;当车速较大时,NO_(X)排放量随着车速和加速度的增加而增大;若车速和加速度同时增加,NO_(X)排放量会显著上升。各工况中的HC排放量一直控制在较低水平。市区路段是影响CO排放的主要路段,市区、市郊和高速路段的NO_(X)排放量都很高,HC排放量在不同路段都很小。
According to the actual road emission test procedures specified in the National VI light vehicle emission standards,the test vehicle is selected to test on the specified road,the on-board emission analysis equipment is used to measure the emission data,and the CO_(2) average window method is used to analyze the difference of emission factors in different road sections.The results show that when the acceleration is small,the CO emission increases with the increase of vehicle speed in the low-speed section,and the emission is basically zero in the high-speed section.When the vehicle speed is large,the NO_(X) emission increases with the increase of vehicle speed and acceleration.If the vehicle speed and acceleration increase at the same time,the NO_(X) emission will increase significantly.HC emissions have been controlled at a low level.Urban road section is the main road section affecting CO emission.NO_(X) emission in urban area,suburb and high-speed road section is very high,and HC emission is very small in different road sections.
