摘　　要：将重型车车载诊断系统(OBD)采集的成都市2023年12月国六重型车OBD远程排放监控数据作为分析对象,筛查NO_(x)超标排放车辆。研究结果表明,统计周期内共检测到826辆NO_(x)超标车辆,占总车辆数的9.93%;超标车辆的NO_(x)排放总量为2735.57 kg,日均排放量为88.24 kg。生成了超标车辆的活动热力图,编制了详细的超标排放重型车辆清单,并将超标车辆清单与成都市现有的年检数据库进行匹配,可进一步与遥感检测、路检、场检等监管业务数据开展横向对比。研究可为成都市重型车排放监管提供数据支撑,有助于进一步推进成都市移动源精准污染防治。In this paper,the on-board diagnostic(OBD)remote emission monitoring data of Stage VI heavyduty vehicles(HDV)collected by the HDV OBD system in Chengdu in December of 2023 were used as the object of analysis to screen vehicles with excessive NO_(x)emissions.The results showed that 826 NO_(x)-exceeding vehicles were detected during the statistical cycle,accounting for 9.93%of the total number of vehicles;the total amount of NO_(x)emissions of the exceeding vehicles were 2735.57 kg,with an average daily emission of 88.24 kg.This study generated a heat map of the activities of excessive vehicles,compiled a detailed list of HDV with excessive emissions,and matched the list of excessive vehicles with the existing annual inspection database of Chengdu,which could be further compared horizontally with the data of remote sensing detection,roadside inspection,field inspection,and other regulatory operations.This study could provide data support for the supervision of HDV emissions in Chengdu,and help to further promote the precise pollution prevention and control of mobile sources in Chengdu.
