Slobodianiuk M. Improvement of fuel injection processes of marine diesel engines

The dissertation is devoted to the solution of theoretical substantiation and development of applied recommendations for maintaining the reliability and efficiency of high pressure elements of the fuel system of a marine diesel engine by determining the differences in each of the pressure elements of the working substance in the operating speed range. The method of probability (regressive) construction of the characteristics of the fuel supply system of marine diesel engines based on the results of experimental tests of the high-pressure fuel pump, the pipeline section and the injector of the diesel fuel system has been proposed. The mathematical model of mechanical processes in high pressure fuel systems has been improved by the regression method with the addition of transient components in fuel equipment. Methods for constructing the characteristics of fuel supply systems for marine diesel engines, by dynamic tests to obtain speed and load characteristics. The method of research of high-pressure fuel systems of marine diesel engines has been further developed. Key words: fuel system, marine diesel, fuel supply characteristics, research technology, fuel system parameters, fuel system operation modes, simulation modeling, software and hardware complex, regression equations, control method
