Model for calculating the characteristics of fuel injection and atomization in diesel when working on alcohol-fuel emulsions

Abstract

Abstract The solution to the problem of air pollution can be the transfer to alternative mixed fuels based on alcohol with the specified physical and chemical characteristics of power engines installed on vehicles and running on oil fuel, which will significantly expand the raw material base for obtaining motor fuels. The mechanisms of crushing a drop burning in an open atmosphere are considered, taking into account the repeated crushing of an emulsion drop as a result of boiling of intra-phase water inclusions and the model of evaporation of the drop in the absence of intensive internal circulation, when the rate of fractional evaporation of each component is determined by its mass fraction.
