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 full implementation of strict regulations on vehicle emissions, in addition to requiring cars with high performance, low emissions, the car fuel also put forward higher requirements. This article selects the representative of gasoline and diesel vehicles, respectively, the use of emission standards for the benchmark fuel and ordinary commercial fuels for exhaust pollutants and fuel consumption test. The results show that there is a significant increase in pollutant emissions and fuel consumption when using commercially available oils compared to the reference oils. Therefore, to ensure the implementation of China’s automobile emissions standards good effect, improve the quality of oil is also a key factor.
