| 中文摘要 |
| 基于我国5个城市实际道路车载测试数据，引入比功率（VSP）和发动机负荷（ES）作为反映机动车行驶状况的特征参数，建立轻型车基于VSP和ES的60个排放单元BIN的排放率数据库，开发了基于工况的城市机动车排放模型（DCMEM），该模型能够计算城市或任一工况下轻型车不同车型的CO、NOxp>和HC排放因子.DCMEM模型计算值与上路测试结果相比，CO与NOxp>偏差<10%，HC<18%. |
| 英文摘要 |
| Vehicle specific power (VSP) and engine stress (ES) were introduced to reflect the driving characteristics of vehicles in China.Emission rates of 60 BIN based on VSP and ES for light-duty vehicles were calculated on the basis of the on-board emission test data in 5 cities of China.The driving cycle-based mobile emission model (DCMEM) was developed to simulate CO，NOxp> and HC emission factors of light-duty vehicles for different cities or driving cycles.The differences in CO and NOxp> emission factors between the DCMEM simulation results and the on-board emissions testing results were less than 10%，and less than 18% for ＨＣ. |
