燃油品质对汽车排放标准实施的影响研究

Study on the Impact of Fuel Quality on Vehicle Emission Standards Implementation

全面实施严格的汽车排放法规,除了要求汽车具有高性能、低排放外,对车用燃油也提出了更高的要求。本文选用具有代表性的汽油车和柴油车,分别使用排放标准规定的基准燃油和普通市售燃油进行排气污染物和燃油消耗量试验。结果表明,与使用基准油相比,汽车使用市售油时污染物排放量和燃油消耗量均有显著的提高。因此,要保障我国汽车排放标准实施的良好效果,提高油品质量亦是关键因素。

The implementation of stringent vehicle emission standards requires not only better performance and lower emission of vehicles, but also higher quality of vehicle fuels. Representative gasoline-fueled and diesel-fueled vehicles were chosen, and specified reference fuels and common commercial fuels were used for this project to conduct exhaust emissions and fuel consumption tests. The result shows that sample vehicles （both gasoline and diesel） which used commercial fuels as test fuels had relatively higher emission and fuel consumption values than those using reference fuelsl Therefore, improving fuel quality is one of the key factors to attain and maintain the effectiveness of the implementation of more stringent vehicle emission standards.
