The aim of the work is to increase the efficiency of machinery units running on biofuels and their mixtures by substantiating the performance of the power supply system and the mixing process. Research methods include theoretical and experimental studies of the process of obtaining and supplying biofuels using a mixing device, comparative studies of diesel engines in bench conditions and MA in conditions of operation on this fuel using modern technical means of measurement and methods of processing these data on personal computers machines (PCs) using standard software packages for electronic computers. This work concerns the current scientific and technical problem of improving the efficiency of machine units when working on fuel mixtures. The difference between the opening of the supply choke DP and BP, which corresponds to the required percentage. This indicator affects the technical and economic performance of the engine, increasing the content of vegetable fuel, leads to an increase in specific fuel consumption, so at ∆S = 0.5, which corresponds to a ratio of 5% DP / 95% BP ge = 267 g / (kWh) , torque when working on mixed fuel 5% DP / 95% BP by 9.9% more than 95% DP / 5% BP, and fuel economy when working on mixed fuel 5% DP / 95% BP by 3, 9% less than 95% DP / 5% BP. Power decreases by 10% when the biofuel content increases to 95%. Using the developed methodology and the experiment conducted on it, the relationship between the factors influencing the work of AIT, presented in the form of regression equations, which allowed to choose the gear ratio and the number of plows depending on the conditions and efficiency of arable tractor. unit using a mixture of fuels.
