摘要： 应用车载排放测试系统(PEMS)，测试了城市车辆在实际道路上的污染物排放特征。污染物包括：CO、总碳氢化合物(THC)、NOx和PM。实验车包括：国Ⅲ、国Ⅵ柴油公交车、压缩天然气(CNG)公交车以及排量均为1.6 L的国Ⅲ、国Ⅵ的出租车；进行了在冷启动和热启动，空调是否开启状态等下的实验。结果表明：实际道路上的排放明显高于实验室认证工况下的排放，在实际道路上实验车辆的气体污染物排放因子均随车速的增加而降低；与柴油车相比，CNG公交车PM排放比较低，但是其NOx和THC排放可能比较高；空调的开启导致公交车的排放明显恶化。

Abstract: On-road emission characteristics of urban vehicles were measured using a portable emission measurement system (PEMS). On-road carbon monoxide (CO), total hydrocarbon (THC), nitrogen oxide (NOx) and particulate matter (PM) emissions were measured. The vehicles included complying with ChinaⅢ,Ⅳemission standards, diesel buses, compressed natural gas (CNG) buses and gasoline taxies with the displacement of 1.6 L complying with ChinaⅢ,Ⅳemission standards. The pollutant emissions of taxies were tested under hot-start and cold-start conditions on chassis dynamometer in laboratory. The impacts of air conditioning on emissions of the buses were researched. Results show that the pollutant emissions levels of the tested taxies under real-world driving conditions are obviously higher than that under the certification cycle conditions; compared to diesel buses, the NOx and THC emission factors of CNG buses are lower, but the PM emission factors may be higher; the use of air conditioning results in serious deterioration of emissions of buses.

Key words: urban vehicles, portable emission measurement system (PEMS), compressed natural gas (CNG) buses, exhaust emission
