Influence of High-Octane Bioadditives on Physical and Chemical Properties of Low-Octane Gasoline

The problem of environmental safety of road transport has become an integral part of the security of Ukraine. The annual increase in vehicle emissions into the atmosphere requires the strengthening of environmental requirements for commercial fuels and exhaust gases of internal combustion engines. Modern cars require high-octane fuel with anti-knock properties, which are characterized by an experimental octane number of 92.95 and 98. For cars with gasoline engines with a compression ratio of up to 8, which are present in the fleet of Ukraine, as well as for trucks of the previous generation, there is a need for gasoline with a lower octane number. The presence of imported cars requires the production of gasoline, which would meet environmental requirements and would have a low cost. In this regard, increasing interest in the use of bioadditives, that would improve the environmental and operational properties of the fuel. World experience shows that the use of 10–15% bioadditives in the gasoline mixture does not have a negative impact on the technical and operational performance of the internal combustion engine. Therefore, the study of the influence on the physical and chemical properties of low octane gasoline is relevant.
