Lazaryan popup.description2 Object of study - the fuel system of diesel engine. Purpose - to improve the energy characteristics of the engine by improving the diesel fuel system that runs on fuel of vegetable origin. Methods of study - an experimental study of thermal and physico-chemical properties of bio-fuel mixtures and their influence on the dispersion of the fuel spray, mathematical modeling of the dynamics of the fuel plume movement and evaporation of the droplets. The analysis of the possible conversion of diesel engines to alternative fuels, particularly fuel of vegetable origin, and the influence of fuel properties on the characteristics of their work. Investigations of thermal and physico-chemical properties of bio-fuel mixtures of diesel fuel and rapeseed oil, and their influence on the atomization and mixing in the cylinder diesel engine. As a result of processing the experimental data obtained by empirical correlations for the thermophysical properties of bio-fuel mixtures. Experimental study of the effect of fuel mixture on the dispersion of the fuel torch. Carried out the design study of the dynamics of flame spray a mixture of biofuels, which improved on the basis of a mathematical model of motion and evaporation of fuel drops and determined the dependence of the change in the relative proportions of the fuel evaporated in the volume of the combustion chamber of a film on the walls of the combustion chamber. The technical proposals to improve the fuel system of diesel engine operation on bio-fuel plant and measures to prevent possible negative effects resulting from changes in the properties of fuel mixtures. Research results can be used in the locomotive economy of railways and design institutes to adapt diesel engines in the transition to biofuels and their improvement.
