Automobile industry is one of the most developed industries in Ukraine and in the world today. The ever-increasing demand for transportation leads to an increase in demand for fuel, which in turn increases its deficit and value. Therefore, the high cost of traditional hydrocarbon fuels and the constant reduction of their world reserves compels scientists to find renewable biofuels. The objective of this paper is to present results of a study aimed at investigating the possibility of using alternative fuels derived from the alcohol industry waste, in pure form and as additives to hydrocarbon fuels. According to the results, the main technical and operational properties of alternative fuels received on the basis of A-92 petrol and fusel oils, experimental values of density, viscosity, distillation temperature on the ENGLER machine, temperature of formation steam congestion, their optimal percentages in the mix for different types were obtained in internal combustion engines. The findings of the research also indicate that an addition of fusel oils to A-92 gasoline leads to improvement of the viscosity-temperature characteristics of formed mixtures and increase in the temperature of formation steam cork, which ultimately reduces the consumption of fuels by 10-12% and also contributes to solving the problem of recycling fusel oils.
