One of the promising areas of modern fuel science and electrical technologies in bioenergy systems of enterprises is the creation of three-component alternative fuel mixtures based on bioethanol, diesel and biodiesel. Such mixtures combine the advantages of each component: bioethanol helps reduce emissions of harmful substances and improves environmental performance, biodiesel increases fuel stability and lubricating properties, and diesel fuel provides high energy density and stable engine operation. The growing interest in such mixtures is due to the need to reduce dependence on traditional petroleum products, increase energy security and introduce more environmentally sustainable energy sources in bioenergy systems of enterprises.

In the context of modern challenges – energy crisis, global warming and environmental degradation – ternary fuel mixtures are becoming particularly relevant. They allow to reduce the harmful impact on the environment, reduce emissions of CO, NOx and soot particles, as well as increase the efficiency of combustion processes in diesel engines. Bioethanol, as an environmentally friendly alcohol of plant origin, improves the process of fuel mixture formation and combustion, contributing to the reduction of exhaust gas toxicity. Biodiesel obtained from renewable raw materials is characterized by high lubricating properties and biodegradability. Its combination with diesel fuel allows to compensate for the decrease in energy density caused by the addition of bioethanol.

Studies show that the ratio of components significantly affects the physicochemical properties of the mixture - density, kinematic viscosity, ignition temperature, heat of combustion and stability. With an increase in the proportion of bioethanol, a decrease in viscosity and ignition temperature is observed, the combustion process improves and the level of toxic emissions decreases. The optimal combination of bioethanol, biodiesel and diesel fuel provides high engine performance and minimizes the negative impact on the environment.

The use of such three-component alternative fuel mixtures in bioenergy systems of enterprises creates the prerequisites for the development of energy-efficient technologies, reduction of the carbon footprint, and integration of renewable energy sources, which is of strategic importance for the energy independence and environmental security of the state.
