摘要
为探究驾驶行为对重型柴油车实际行驶污染物排放的影响,利用车载便携式排放测试系统(PMES,portable emissions measurement system)对3辆车分别进行了平稳驾驶、正常驾驶和激烈驾驶共9次PEMS试验。对每辆车前后3次试验的市区、市郊、高速路段和总行程路段动力学参数v·a pos [95]和比排放进行了计算,并利用动力学参数v·a pos [95]对污染物排放特性影响进行了深入分析。结果表明:相较于平稳驾驶,正常驾驶和激烈驾驶行为下3辆车NO_(x)比排放增加33.73%~621.10%,PN比排放增加21.26%~122.40%;同时CO比排放与车辆动力学参数v·a pos [95]之间无明显影响关系,市郊、高速路段NO_(x)比排放和PN比排放与车辆动力学参数v·a pos [95]存在较强的相关性,可见其驾驶行为对车辆排放的影响不容忽视。
In order to investigate the impact of driving behavior on real driving emissions(RDE)of heavy-duty diesel vehicles,a total of 9 times of smooth driving,normal driving and rough driving were carried out on three vehicles using the portable emissions measurement system(PMES).The dynamic parameters v·a pos [95] and emission factors of the urban,rural,motorway section and total travel distance of each vehicle were calculated before and after the three tests,and the dynamic parameters v·a pos [95] were used to analyze the effects of pollutant emission characteristics.The results show that compared with smooth driving,the NO_(x) emission factors of the three vehicles under normal driving and rough driving behavior increase by 33.73%621.10%and the PN emission factors increase by 21.26%122.40%.At the same time,the correlation between CO emission factors and the dynamic parameters v·a pos [95] is not obvious,but the NO_(x) emission factors and PN emission factors of suburbs and high-speed sections have a strong correlation with the dynamics parameters v·a pos [95].It can be seen that the impact of driving styles on vehicle emissions cannot be ignored.
