摘　　要：对装载柴油机的轿车模态排放特性进行了试验研究,分析了柴油轿车NEDC循环HC、CO、NOx和CO2的模态排放特性。结果表明,在NEDC循环中,ECE城区行驶循环第1个循环的HC和CO排放量较高,分别占NEDC循环HC和CO总排放量的60%和89%;EUDC循环排放的NOx和CO2排放量较高,分别占NEDC循环NOx和CO2总排放量的52%和47.7%。A research on modal emission property of a diesel car was made,and the modal emission property of HC,CO,NOx and CO2 from the diesel car in NEDC cycle was analyzed.The results show that HC emissions mass and CO mass in the first ECE urban drive cycle are a little higher than the other cycles,which account for 60% and 89% respectively in the total emission mass in NEDC cycle.The percentage of NOx mass and CO2 mass of EUDC cycle are higher than other cycles,which account for 52% and 47.7% in the total emission mass of NEDC cycle respectively.
