| Abstract: |
| The purpose of this paper is to calculate vehicle emissions from high power and large tonnage diesel vehicle. According to “Guidelines for Design of Ventilation of Highway Tunnels” and the report provided by The World Road Association (PIARC) in 2012, the pollutant emissions of 32 t heavy-goods diesel vehicles and ventilation volume required to dilute pollutants are calculated respectively, and the differences between the two calculation methods are compared and analyzed. Propose reasonable suggestions for vehicle type factor and altitude factor for “Guidelines for Design of Ventilation of Highway Tunnels”. According to the report provided by PIARC in 2012, in 0~2000 m altitude area the emissions of CO, NOx and PM from domestic 32 t diesel vehicle are 88.6, 166.0 m3/(h.veh) and 84.2 m2/(h.veh) respectively. The air volume flow necessary for pollutant dilution is about 33,000 m3/h if air pollution of NOx is considered. If not, 28,000 m3/h is required. Combined with project experience, it is suggested the report provided by PIARC in 2012 should be the suitable method for calculating high-power and large-tonnage HGV emissions. |
