中文摘要:
      柴油车排放的NOx量大且占比高,污染状况不容忽视。针对目前柴油车排放环保定期检验中缺少NOx检测方法和标准的情况,采用非分散红外法对210辆柴油车NOx排放进行实测。结果显示,加载减速检测工况中80% VelMaxHP工况点可用于柴油车NOx排放检测,有利于识别高排放车辆。该方法的推广应用,将为今后柴油车后处理装置的效果监管和车辆NOx实际排放的日常检测提供重要技术支撑。
英文摘要:
      It cannot be ignored that diesel vehicles emit large amounts of NOx. Nowadays, NOx detection methods and standards are lack during the process of regular inspection for diesel vehicles. On the 210 diesel vehicles, NOx emissions were measured by NDIR. Detection results showed that 80%VelMaxHP operating points of lug-down condition can be used for NOx testing of diesel vehicles, which helps the identification of high emission vehicles. The application of this method will provide important technical support for the monitoring of the effectiveness of diesels′ after-treatment devices as well as the annual check of NOx emissions.
