  • 摘要: 对低温环境中乙醇汽油和普通汽油的冷凝水、CO、HC、NOx和CO2排放特性进行了研究,并对5种排放物的形成机理和排放趋势进行了分析。ECE工况(-20、-10和0 ℃)和怠速工况(-30、-20、-10和0 ℃)下,乙醇汽油和普通汽油的冷凝水排放量主要受含氢量、车辆构造和外界环境的共同影响。ECE工况中冷凝水的总体排放趋势是随着温度降低而增加,乙醇汽油的总排水量持平或略低于普通汽油。-10 ℃时乙醇汽油的高含氧量能促进燃烧速度和燃烧效率,减少CO和HC排放,增加NOx排放;0 ℃时低温环境和乙醇的高汽化潜热会影响可燃混合气形成和燃烧速度,降低缸壁温度,增加CO和HC排放。
    Abstract: The emissions characteristics and trends of condensate water, carbon monoxide (CO), hydrocarbon (HC), nitrogen oxides (NOx), and carbon dioxide (CO2) from ethanol gasoline and regular gasoline in a low-temperature environment were studied, and the formation mechanisms were analyzed. Under ECE conditions (-2, -10 and 0 ℃) and idling conditions (-30, -20, -10 and 0 ℃), the condensate water discharge of ethanol gasoline and regular gasoline were mainly affected by the hydrogen content, vehicle structure, and external environment. Generally, condensate water in ECE conditions increased as temperatures decreased, while the total water amount from ethanol gasoline was equivalent to or less than that from regular gasoline. At -10 ℃, the high oxygen content in ethanol gasoline could promote the velocity and combustion of combustion, which could then decrease CO and HC emissions, as well as increase NOx emissions. At 0 ℃, the high latent heat of vaporization and low environment temperature could affect the formation and combustion velocity of the inflammable mixture, which could increase CO and HC emissions.
