| 目的 计算大功率大吨位级重型柴油车的污染物排放量。方法 根据《公路隧道通风设计细则》和世界道路协会(PIARC)2012年技术报告，分别计算32 t重型柴油车的污染物排放量和稀释污染物所需的通风量，对比分析两种计算方法的差异。结果 对《公路隧道通风设计细则》中柴油车的车型系数和海拔高度系数提出建议。根据世界道路协会(PIARC)2012年技术报告，在0~2000 m低海拔地区，国产32 t柴油车的CO、NOx和烟尘排放量分别为88.6、166.0 m3/(h.veh)和84.2 m2/(h.veh)，如果考虑NOx的空气污染，稀释单辆国产32 t柴油车排放污染物所需空气量约为33 000 m3/h；如果不考虑NOx的空气污染，所需空气量约为28 000 m3/h。结论 结合工程实际，建议大功率大吨位级重型柴油车的污染物排放量根据世界道路协会(PIARC)2012年技术报告进行计算。 |

| 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. |
