| 摘 要： | 采用机动车实际上路排放测试系统对北京、重庆和成都3城市27辆轻型车进行了测试和分析;采用发动机比功率VSP、发动机负荷ES和排放单元BIN分析了轻型车瞬态排故的特征及影响排放的主要因素.结果表明.发动机技术和累计行驶里程对排放的影响很大,而VSP等概念还反映了道路坡度对排放因子的影响;由于城市道路坡度的差异,导致同一测试车辆在重庆和成都2个城市的排放水平相差10%～100%.

| Abstract: | Twenty-seven light duty vehicles were tested in Beijing,Chongqing,and Chengdu using an on-board vehicle emission test system.Vehicle Specific Power(VSP),Engine Stress(ES),and BINwere introduced to analyze the instantaneous emission characteristics of the vehicles and the major factors influencing vehicle emissions.The results showed that engine technologies and accumulative vehicle mileage affect the emission rates significantly.Besides,concepts such as VSP also reflect the influence of variation in road height on vehicle emission factors.The emission factors of the same vehicles varied by 10%-100% in Chongqing and Chengdu due to differences in the average road gradient of the two cities. |
