【摘要】 统计了中国七大地区燃油品质的特点,分析了各地区燃油组分的组成和特点;研究分析了燃油品质对汽车发动机排放的影响因素,通过使用华中地区和西南地区的燃油实验,对不同燃油,适当调整发动机的过量空气系数、点火提前角,测试其发动机COx(碳氧化合物)、HC、NOx(氮氧化合物)等排放变化,指出了针对不同地区燃油芳烃、烯烃的特点,适当调整发动机的过量空气系数或点火提前角,可使发动机的工作相对平稳些,其发动机排放物有所降低和控制。更多还原

【Abstract】 Quality,composition,and characteristics of fuel from 7 areas of P.R.China were analyzed.Fuel quality factors influencing engine emission performance were studied.Using fuel from the HuaZhong and XiNan areas,engine COx,HC,and NOx emissions were tested by adjusting the excess air coefficient and the advanced ignition angle.In light of the characteristics of aromatic hydrocarbon and alkenes of fuel from different areas in P.R.China,we have shown engines can operate smoothly and engine emissions can be decreased when the excess air coefficient and the advanced ignition angle are properly adjusted.更多还原
