Vrublevsky O. Scientific bases of parameters choice of accumulating fuel equipment with electronic control for high-speed diesel engine

Processes in accumulating fuel equipment with electronic control for high-speed diesel engine. Solving of problem of choice of accumulating fuel equipment with electronic injection control for high-speed diesel engine that allows to develop and implement fuel equipment with flexible control system of fuel supply parameters. The fundamental aspects of internal combustion engines theory, the theory of hydrodynamics and magnetism lie in the basis of the given dissertation research. The author has offered the of choice of parameters of accumulating fuel equipment with electronic control the basis of witch is composed of the following: the mathematical model of fuel supply process; the method of multiparametric verification of mathematical model of processes occurring in accumulating fuel equipment. The quantitative effect of constructive and adjusting parameters of electro fluidic injector, high pressure fuel pump on fuel supply process that allowed to determine the parametric and functional limitations at problem definition of optimal parameters search is determined. The supplementary criteria for accumulating fuel equipment quality estimation - productivity criteria and power expenditure criteria on high pressure fuel pump actuator are offered and pounded. The perspective method of required operation speed support of electro magnetic actuator of electro fluidic injector valve by means of magnetic conductors application that include, in comparison with existing analogues, magnetically hard and soft materials is offered. The possibility of electro fluidic injector actuator with application of magnetostriction phenomenon that can be observed in intermetallic compound Terfenol-D is scientifically grounded. The offered scientific principles for choice of parameters of accumulating fuel equipment with electronic control for high-speed diesel engine are implemented according to the method that includes the following: the mathematical model of fuel supply process, the method of mathematical model verification, the optimization method, the method of experimental research of fuel equipment at engineless and prompt stands. The results of accumulating fuel equipment tests became the basis for electronic fuel injection implementation in home high-speed diesel engine, developed at KP KhCBD. The model of fuel supply process and the method of experimental investigation offered in the given thesis are introduced into the studying process at students training on specialty 7.090210 - internal combustion engines at KhNAHU.
