The analysis of resource use shows the annual dynamics of increasing the use of fossil fuels. A special place in the structure of the use of motor fuels falls on diesel fuel of petroleum origin; the annual increase is about 5%. Today, European trends are aimed at reducing the use of diesel engines and diesel biofuels as sources of nitrogen oxide pollution. One way to reduce the pressure on the environment is to use biofuels, which by their nature are renewable resources. However, the use of diesel biofuel in its pure form requires significant changes in the design of the diesel engine and will require a significant increase in the area occupied by oilseeds. Many countries have a propensity to add about 5% of diesel biofuel to diesel fuel of petroleum origin. This approach does not significantly affect the environmental situation or reduce the amount of fossil fuels. The study and analysis of the fractional composition of diesel fuel of petroleum origin and diesel biofuel based on methyl esters of fatty acids of plant oil are performed. Diesel biofuel has significantly higher boiling points compared to diesel fuel. The obtained results indicate the possibility of adding 20% of diesel biofuel to diesel fuel of petroleum origin. When creating such a fuel mixture, it is advisable to replace part of the heavy fractions of diesel fuel of petroleum origin with diesel biofuel. Studies of physical and mechanical properties have shown the feasibility of using this method when creating a fuel mixture. The obtained results allow increasing the quantitative use of diesel biofuels and reducing the negative impact on the environment.
