摘要
统计了我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,适当调整发动机的着火提前角,测试其发动机CO2、HC、NOx的排放变化,指出了针对燃油芳烃偏高的燃油,如华中地区燃油芳烃偏高的特点,适当减小发动机的着火提前角,可使发动机的工作相对平稳些,其HC有所下降,同时NOx也有所降低。
It discusses and analyzing the fuel quality and composition and characteristics of 7 areas in our country. By using the fuel of HuaZhong and XiNan area,the engine CO2,HC,NOx emissions are tested under adjusting the advanced ignition angle suitably form researching and study influence factors ,engine can operate smoothly and HC and NOx emission can be decreased when the advanced ignition angle is diminished properly to aim at the fuel aromatic hydrocarbon is high partially such as HuaZhong area fuel.
