- 摘要：通过调查研究天津市机动车车型构成、保有量、车辆行驶状况、气象数据和油品等基础数据，利用COPERT IV模型计算了在国1、国2、国3、国4和国5排放标准下机动车尾气中CO、NOx、VOC和PM2.5的排放因子.应用车载测试系统在实际道路上对国4柴油货车的排放因子进行了测量，并将模型结果与实测结果进行了比较，研究表明，国4排放标准下，污染物排放实测数据普遍高于模型模拟数据.对于轻型载货柴油车而言，实际道路测量的CO、NOx、VOC和PM2.5的排放因子分别是模型模拟数据的2.5、4.3、1.9和1.2倍；对于中型载货柴油车而言，以上污染物的实测排放因子分别是模型的1.3、2.1、1.0和1.2倍；对于重型载货柴油车而言，以上污染物的实测排放因子分别是模型的1.7、1.9、1.1和1.2倍.
- Abstract：Based on the investigation of Tianjin basic vehicular data including vehicle type composition, population, driving conditions, meteorological data and oil quality, etc. COPERT IV model was applied to calculate the emission factors of vehicle exhaust pollutants with different emission standards of China-1, China-2, China-3, China-4 and China-5, including carbon monoxide(CO), nitrogen oxides(NOx), volatile organic compounds(VOC) and particulate matter(PM2.5). Emission factors of China-4 diesel trucks were measured by portable emission measurement system on real road. The emission factors from modeling simulation and on-board test were compared and the results showed that:the test data were generally higher than the calculateddata conforming to the China-4 emission standard. For light duty diesel trucks, the tested emission factors of CO, NOx, VOC and PM2.5 were 1.5, 3.3, 0.9 and 0.2 times higher than the calculated data, respectively. For medium duty diesel trucks, the tested emission factors of the above four pollutants were 0.3, 1.1, 0和0.2 times higher than the calculated data, respectively. Moreover, for heavy duty diesel trucks, the tested emission factors of the pollutants were 0.7, 0.9, 0.1 and 0.2 times higher than the calculated data, respectively.
