Reducing the technosphere impact of agricultural machines by expanding the low-temperature applicability of alternative fuels

Abstract

Abstract The subject of the study was alternative fuels used in agricultural machines. As an alternative fuel, a mixture consisting of diesel fuel, rapeseed oil and a targeted additive was considered. The main task was to develop a method for expanding the limits of low-temperature properties of alternative fuels used in tractors of agricultural machines. Because of the studies, a mathematical calculation model for determining the clouding temperature of an alternative fuel with the addition of a targeted additive was developed, the obtained calculation mathematical model was tested with experimental data, which showed 96 % convergence of theoretical calculations with experimental data. The low-temperature applicability of alternative fuel has been expanded by 9 degrees, and it has been proven that for normal operation of a diesel engine in low temperature conditions on fuel with rapeseed oil additives, it is advisable to use a multifunctional additive DIFRON H372 up to 2 %, which allows reducing the level of technospheric impact on the environment.
