ECONOMIC EFFECTIVENESS OF USE OF BIOETHANOL ON INTERNAL COMBUSTION ENGINES
Journal Title: Автомобильный транспорт - Year 2018, Vol 42, Issue
Abstract
Problem. Research of alternative types of motor fuels from renewable sources is becoming widespread in Ukraine and in the world. This is due to the increased environmental requirements for commercial fuels and exhaust gases of internal combustion engines through the introduction of Euro 6 standards. The problems of environmental safety of road transport have long been an integral part of the environmental safety of each country. Significance and acuteness of this problem grow with each passing year due to the annual increase in emissions of vehicles by polluting substances into the atmosphere (an average of 3–5 %). The purpose of research is to assess the feasibility of using bioethanol in equivalent fuels, taking into account the economic efficiency, which was calculated on the basis of commercial fuel costs. Methodology. In studies of the economic efficiency of using bioetha-nol as an additive to gas, the necessary condition is to provide the same octane number of equivalent fuel compared with commercial gasoline. In the final result, the authors received dependence of the price change of the gasoline used, depending on the con-tent of bioethanol in it. In processing the results of the research methods of least squares and mathemat-ical statistics were used. Result. Authors obtained the dependence of changes in the price of gasoline, depending on the amount of bioethanol used. The study found that the use of bioethanol in a mixture with gasoline can reduce fuel consumption due to the use of fuel mixtures of cheaper ethanol and the use of low-octane low-cost gasoline. From an ac-ceptable price for petrol and bioethanol from stud-ies, it follows that with an increase in the percent-age of bioethanol in equivalent fuels, up to 80 % reduces the cost of the received alternative fuel to 30 %. Research on the effectiveness of using bioeth-anol as additives to low-octane gasoline is original as all previous studies are based on the mixing of alternative fuels with commercial gasoline and pro-vides the most cost-effective. Research results can be practically used by scientists and engineers of the relevant profile to create mixed alternative fuels.
