Physical and chemical properties of innovative and high-quality grades of gasoline

Studies of the physicochemical properties of traditional gasoline (G), innovative gasoline (IG) and high-quality gasoline (HQG) have been carried out. The purpose of this work was to analyze the physicochemical properties of innovative, high-quality grades of gasoline, to compare the performance of these fuels with those of conventional fuel that does not contain substances that improve the operational and environmental qualities. The research of the properties of gasolines was carried out using an automatic apparatus for distillation of petroleum products ARNS-1E, indicator (octanometer) OKTAN-IM, gas analyzer INFRACAR 5M3T, single-cylinder, 4-stroke, overhead valve engine (Biggs Stratton). It has been established that the density of gasolines, the final boiling point, the residue in the flask and the acidity correspond to the GOST standards. A six-month storage period for fuel samples does not affect the parameters of the fuel, its physical and chemical stability. It is shown that substances that improve the properties of innovative and high-quality fuels do not affect the result of measuring the octane number of gasoline. It has been established that the chemical stability of improved grades of gasoline is higher than that of traditional fuel. It is shown that innovative and high-quality gasoline is superior to gasolines that do not contain combustion-improving substances in terms of combustion efficiency. A similar conclusion was made for nitrogen oxides, the content of which is associated with the presence in gasoline of components that increase the temperature of gases that occur in the combustion chamber of the power unit.
