Scientific Bulletin of Namangan State University


the study was carried out by selecting composite additives to adapt the indicator "octane number" to the desired parameters. A separate substance, A-18, has also been studied as a flame-making agent, determining its effectiveness in various concentrations. In connection with the work, the optimal number of additives that meet the requirements of GOST 8226-2015 octane number of gasoline fraction in the desired composition was selected, and the influence of changes in the physicochemical and operational properties of gasoline fuel was studied
