RESEARCH OF WATER-DIESEL MIXTURE PREPARED IN A DYNAMIC DEVICE FOR AUTOMOTIVE TECHNOLOGY

Abstract

Water-fuel emulsions are used mainly with an emulsifying system, which significantly increases the cost of such fuel. At the same time, the use of fuel emulsions without expensive emulsifiers has not been sufficiently studied, which is an urgent scientific problem. The article describes experimental research on the study of a water-fuel emulsion prepared in a dynamic apparatus. The analysis of injection of conventional diesel fuel and the resulting mixture containing 17% of the aqueous phase and DT-L-K5 fuel in the amount of 83% was carried out. To study the process of preparing the mixture, a pilot plant was developed and created. The paper investigates the processes of the formation of a fuel jet when fuel is injected from a nozzle atomizer. The results obtained showed the advantage of using a water-diesel mixture in comparison with the considered diesel fuel. To confirm the experimental data, field studies were carried out to determine the fuel consumption when the D-241 engine was running. The conditions for carrying out transport work on the MTZ-80 tractor were reproduced when operating on diesel fuel and on a water-diesel mixture. It has been experimentally established that when the aqueous phase is introduced in an amount of 17% in relation to the volume of fuel in the prepared water-diesel mixture, the specific fuel consumption decreases by 17% when operating on the emulsion.
