Assessment of the quality of alternative fuels for gasoline engines

Abstract

The use of alternative fuels is a strict requirement of the present day. The threatening ecological situation of the environment, the constant growth of the fleet, the high price of petroleum products and the import dependence of Ukraine in oil fuels does not raise doubts about the need to develop, improve the properties and expand the range of biofuels. One of the possible solutions to these problems is the use of bioethanol, both in pure form and as an additive to gasoline of oil origin. The purpose of this article is to study the effect of ethanol on the performance properties of traditional gasoline, the search for the optimal ratio of alcohol and gasoline for use in internal combustion engines. Experimental studies have shown that the concentration of ethanol in gasoline 5–7% performance of physical and chemical properties of the fuel does not change at all. If we add 30% ethanol, we have a serious change in the corresponding indicators, and to ensure the physical stability of the fuel, the reduction of its octane number should be sure to use the appropriate additive. Therefore, the use even in high concentrations of alcohol in the production of alternative fuels for gasoline engines is justified.
