When operating a diesel engine on a mixture of fuels with an increase in the content of BP, the increase in fuel consumption is up to 11.61%, saving money on the purchase of fuel up to 19%. The use of dynamic adjustment of the percentage of the fuel mixture provides economic benefits without compromising the technical performance of the engine. Fuel mixture consumption increases by 5.9%, but its cost decreases by 8.6%. When using a mixture of fuels with diesel YaMZ-238, the reduction of fuel costs reaches 26.4%, depending on the content of biodiesel in the mixture. When using dynamic control of the percentage of the fuel mixture, its consumption increases by 8.7%, but the cost savings will be 14.4% compared to the use of diesel fuel, which is equal to the use of a mixture of 66% BP and 34% DP, which reduces costs by 145 , 57 UAH per 100 km. To improve the diesel power supply system, it is necessary to install additional elements, most of which are standard components for the base diesel; it is necessary to replace a part of details of the power supply system of the diesel engine on details steady against influence of BP. Equipping cars with a system of dynamic regulation of the percentage of the fuel mixture and its maintenance is possible at service stations after training and instructing staff and providing it with components. According to the results of calculations, the payback period for the installation of a system of dynamic control of the fuel mixture for the operation of the car's diesel engine is 9 months. The above scientific results have the following practical value: first - to assess the impact of biodiesel on the efficiency of internal combustion engines; secondly - can serve to improve the technical and economic performance of the internal combustion engine; thirdly - allow to improve the power supply system of the internal combustion Product Description popup.authors Branitsky Yuriy Yu Burlaka Serhii A Galushchak Oleksandr O Гунько Ірина Василівна Kaletnik Hryhoriy M Kupchuk Ihor M Shargorodsky Serhiy A.
