Modeling of Processes Into Electro-Hydraulic Valves of an Engine’ Fuel System

Abstract

This work proposes the way to increase reliability of fuel feeding mathematical model by taking into account processes from the inside of electro-hydraulic valves - like parts collision during their movements; fuel flow in the clearances between the supports and moving parts; effect of joined mass. The equations to describe the mentioned processes and modeling results are shown. Practical value for received results is the possibility to evaluate effectiveness for changes proposed to be made in the construction and designed control algorithms for multipurpose valves of the given type
