Improving the Efficiency of the Use of Biodiesel Fuel Mixtures in the Systems of Autonomous Energy Supply of Agricultural Enterprises

Abstract

The research is devoted to solving important tasks of interdisciplinary research work on the topic: «Development of scientific and technical support for energy autonomy of the agro-industrial complex based on environmentally efficient use of agrobiomass for biofuel production», state registration number 0122U000844, implementation of which is planned for 2022–2024 at the expense of the state budget of Ukraine.The use of fossil fuels leads to environmental pollution and climate change in general. To ensure energy security and to improve the environmental conditions necessary for the use of alternative energy sources and to determine their potential impact on the climate and our planet. Looking for more in-depth analysis of all aspects of the use of biofuels in order to determine their potential through the use and economic components.During studies carried out comparing the performance of different fuels. It has been found that the fuel obtained from biomass is advantageous in environmental protection performance in the production process, is absorbed when the biomass in the growth process and the carbon dioxide in operation.Analyzing the following requirements fuel when executed estimate (European) emission standards (CO, ShNu, NO X) for the test cycle, reduced CO2 emissions, the minimum consumption of natural resources and energy, and minimal impact on the environment in its life cycle. There are theoretical ways to increase the effective capacity of machine units and to determine the impact of this increase on the technical, economic and environmental efficiency of a diesel internal combustion engine. It has been found that the use of biofuels from plant oils can reduce the use of fossil fuels and environmental improvements. However, when using a fuel, wherein the content of the organic component exceeds 50%, i.e. deterioration of technical and economic parameters of the diesel engine. Among the mixed fuel we studied the best technical and economic characteristics of a mixture containing 70% of mineral fuels and biofuels 30% rapeseed oil. Thus, the subject to reach a dosage adjustment of the change of the fuel mixture, depending on the speed of rotation of the crankshaft of the engine the best environmental performance.
