To solve the problem of improving the quality of fuels used in internal combustion engines, a comprehensive approach is proposed, which includes the use of additives to gasoline, increasing the detergent properties in parallel with completeness of fuel combustion. The results of laboratory studies of present-day gasolines as well as the results of motor-bench tests of a gasoline injection engine when it operates on gasolines of various group and oxygenate compositions, including those containing detergent additives and a combustion activator are presented. The relation of the group and oxygenate gasoline compositions, concentration of the introduced additive with the technical, economic and environmental characteristics of the gasoline engine is considered. The optimum concentration of multifunctional additive introduction into gasolines of different group composition is determined. It is shown that the efficiency of the additive deteriorates with increasing content of oxygenates.
