| Abstract: | Six typical China-VI heavy-duty diesel vehicles were selected for the real driving emission test with Portable Emission Measurement System (PEMS), and the CO, NOx, and PN emission characteristics of heavy-duty vehicles were evaluated by the work-based window method. The results showed that the emission aftertreatment devices of heavy-duty diesel vehicles could effectively control the CO and PN emissions under real driving conditions, but there was significant uncertainty in NOx emission. Up to 46.68% of the high specific NOx emission windows were removed from the real driving emission evaluation by the work-based window method adopted in the current China-VI emission regulation, which led to serious underestimation of real NOx emissions from heavy-duty vehicles under real driving conditions, especially in urban traffic congestion. In the subsequent revision of the emission regulations, a more scientific and reasonable evaluation method should be introduced to evaluate the real driving emissions of heavy-duty vehicles. |
