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(DC MEM),该模型能够计算城市或任一工况下轻型车不同车型的CO、NOx和HC排放因子.DC MEM模型计算值与上路测试结果相比,CO与NOx偏差<10%,HC<18%.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, NOx and HC emission factors of light-duty vehicles for different cities or driving cycles.The differences in CO and NOx emission factors between the DCMEM simulation results and the on-board emissions testing results were less than 10 %, and less than 18 % for HC.
