In order to understand the emission characteristics of National VI heavy-duty diesel vehicles on long slopes under full load in plateau environment, an N3 heavy-duty diesel vehicle was tested on actual road emissions to study the instantaneous emissions of pollutants from heavy-duty diesel vehicles on long uphill and downhill slopes and compare their emission factors. The results show that the engine exhaust temperature decreases with the decrease of altitude. When heavy diesel vehicles are going uphill, with the increase of road slope, NOx emissions show a downward trend and PN emissions show an upward trend. However, when heavy diesel vehicles go downhill, with the decrease of road slope, NOx emissions show an increasing trend and PN emissions show a decreasing trend. When heavy diesel vehicles go uphill, the pollutant emission is worse than that when they go downhill.
