Stocks of fossil fuel oil are exhausted. Explored oil reserves of traditional extraction in the world will last 40-50 years of extraction. Still about the same reserves of oil, that is extracted from shale seams and bituminous sands. In Ukraine, its own oil production accounts for only 20% of its needs. Therefore, it is necessary to find new sources of energy that could replace oil fuels. These resources include biofuels, which can also be used to supply diesel engines. The article analyzes diesel biofuels, which can be replaced by petroleum diesel fuels: dimethyl ether, vegetable oil and biodiesel. It has been established that dimethyl ether has a low heat of combustion, in a result is significant reduction in engine power. Vegetable oil by its properties is significantly different from diesel biofuels. Yes, it has a much higher viscosity, which leads to the formation of larger droplets, which burn significantly worse. And due to the fact that during the shooting, it polymerizes, forming a stable pellicle that covers the nozzles, through which there is spray of fuel in the engine, the latter may break down. Therefore, today, the most suitable biofuel for Ukraine, which can both replace physical and energy indicators with mineral diesel, is methyl ether or biodiesel.
