Low-carbon fuel is the main trend in the development of oil refining in leading countries. Likewise, efforts continue optimizing internal combustion engines for increasing their fuel economy, and therefore exhaust emissions will be reduced. This research proposes a novel approach for producing low-carbon high-octane oxygenated environmentally friendly motor gasoline based on low-octane hydrocarbon fractions. Experimental studies of the antiknock performance for four representatives of oxygenated compounds, involving bioethanol, methyl tertiary butyl ether (MTBE), isopropanol, and 2-methylfuran with low-octane hydrocarbon fractions, as well as low-octane blends of individual hydrocarbons of surrogate fuels were carried out. Additionally, the change in antilocking performance of oxygenated compounds has been dependent on their types and group composition of the base low-octane motor fuel. The results illustrated that high-octane environmentally friendly motor gasolines RON 91 and RON 95 have been produced. Besides, the injectivity of hydrocarbons to oxygenated compounds by the ability to increase the octane rating by the research method will increase in the series: olefins < naphthenes < aromatics < paraffins, and by the motor method:naphthenes < olefins < aromatics < paraffins. Finally, environmentally friendly motor gasoline can decrease the environment impacts, reduce the overhead charges, as well as maximize the product quality.
低碳燃料是领先国家炼油发展的主要趋势。同样，人们也在不断努力优化内燃机，以提高其燃油经济性，从而减少废气排放。本研究提出了一种基于低辛烷值烃类生产低碳高辛烷值含氧环保车用汽油的新方法。实验研究了四种含氧化合物（生物乙醇、甲基叔丁基醚（MTBE）、异丙醇和 2-甲基呋喃）与低辛烷值烃类以及替代燃料中单个烃类的低辛烷值混合物的抗爆性能。此外，含氧化合物的抗爆性能变化取决于其类型和基础低辛烷值车用燃料的基团组成。结果表明，生产出了辛烷值为 91 和 95 的高辛烷值环保车用汽油。此外，通过研究方法提高辛烷值的能力，烃类对含氧化合物的注入性将按以下顺序增加：烯烃<环烷烃<芳烃<烷烃，而按发动机方法则为：环烷烃<烯烃<芳烃<烷烃。最后，环保车用汽油可以减少对环境的影响，降低运营成本，并最大限度地提高产品质量。
