Performance of a diesel injector operating on reverse fuel emulsions

The relevance of the work is due to the growing interest in alternative fuels in the face of increasing demand for energy resources. Insufficient lubrication of the elements of fuel equipment when using ethanol—fuel emuLSIon is further complicated by the fact that today there is no unified approach to determining the LSI of fuel. The paper presents the results of a study of the operability of a diesel nozzle on reverse fuel emuLSIons based on diesel fuel and ethanol. Disclosed is a method of determining the lubricity limit value of a fuel emuLSIon. Mathematical relationship between fuel lubricity index and sprayer needle mobility is established. The study methods included experimental tests on a M107-CR bench. Theoretical assumptions have been experimentally confirmed — the content of ethanol in the fuel emuLSIon should not exceed 80.97% of the total mass. Practical importance lies in the possibility of optimizing fuel emuLSIon compositions for use in diesel engines. The results of the study make it possible to determine the permissible concentrations of the fuel emuLSIon components that ensure the operation of the fuel equipment.
