摘要
为了研究重型车远程监控与实际道路试验数据的差异,该文通过对2辆样车拟合结果以及对100辆样车的统计结果分析,研究了远程监控平台接收数据与便携式排放测试系统(PEMS)测量数据的一致性。结果表明:PEMS设备的实测或计算结果可以应用于对重型车远程监控数据的数据一致性核查,二者车速数据一致性结果较好,燃料流量和进气量数据一致性结果次之;对于NOx排放应适当放宽数据一致性要求;远程监控数据可以较好地反映车辆实际道路中的运行工况;远程监控和PEMS试验数据的功基窗口基本一致,但NOx传感器精度误差有可能导致远程监控功基窗口法的计算结果与PEMS实测数据产生较大偏差。
In order to study the difference between the remote monitoring data of heavy-duty vehicles and the actual road test data,this paper studies the consistency of the data received by the remote monitoring platform and the measurement data from the portable emission measurement system(PEMS)by fitting the results of two vehicles and analyzing the statistical results of 100 vehicles.The results show that the measured or calculated results from the PEMS equipment can be applied to the consistency verification of the remote monitoring data of heavy-duty vehicles;The consistency of the speed data is acceptable,followed by the consistency results of the fuel flow rate and the intake flow;For NOx emissions,the data consistency requirements should be more flexible.The remote monitoring data can reflect the actual operating conditions of vehicles on the road.The work-based windows from the remote monitoring data and the PEMS test data are basically the same.However,the accuracy error of NOx sensors may lead to a large deviation of the work-based window method calculation results between the remote monitoring and the PEMS measurement.
