Abstract
Currently, the search for alternative renewable fuels for internal combustion engines is becoming strategic. At the same time, it is necessary to work on adapting and improving the design of power transport units, conduct research on optimizing the composition of fuels, their quality and safety, and improve the combustion process of fuels in the cylinder. Vegetable oil-based fuels and alcohol-based fuels are well established and widely distributed. Their valuable property is that when burned, they are less prone to the formation of toxic components and carcinogens. The purpose of this work was to analyze the characteristics of the diesel engine and the combustion process when working on ethanol and rapeseed oil when changing the ratio of cyclic feeds. At the same time, diesel fuel was not used and alcohol fuel was injected into the combustion chamber by a separate injector and ignited with a flame from the rapeseed oil. A 2F10,5/12,0 tractor diesel was upgraded to run on alternative fuels. The article presents the effective characteristics, indicator diagrams, the functions of heat dissipation and the average gas temperature at various portions of the rapeseed oil. The optimal relations portions of the fuels (ethanol and rapeseed oil) is established and justified.
