Abstract

The purpose of this article is to perform research to improve the stability, quality and efficiency of gasoline-alcohol fuel compositions, as well as obtaining high-octane gasolines corresponding to the modern standards with the addition of alcohols and their mixtures to these gasolines. Research methods: The article considers physicochemical methods for studying the stratification of alcohol-gasoline mixtures, determining the water content in them, as well as determining the octane number of alcohol-gasoline compositions. Results: The raw material base and possibilities of bioethanol production in Ukraine as an ecological additive to gasoline and as a way to increase their octane number were studied. Stratification temperatures of alcohol-gasoline mixtures and octane numbers of A-92 gasoline with different alcohol content were determined. Discussion: It is proposed to use higher concentrations of ethanol (bioethanol) in gasoline mixtures more than 40% of alcohol, because it does not require dehydration. It is proposed to use an additional fuel pump, which would work only for mixing the fuel mixture, to prevent stratification of the fuel-ethanol composition during its long-term storage in the car’s tanks.
