Abstract:V prispevku je predstavljen matematični model za numerično simuliranje procesa vbrizgavanja v elektronsko krmiljenem visokotlačnem vbrizgalnem sistemu ECD-U2 za dizelske motorje tovornih vozil. Matematični model temelji na predpostavki, da je tlak vbrizgavanja na izbranem delovnem režimu nespremenljiv. Glede na to je pozornost posvečena predvsem procesom, ki potekajo v vbrizgalni šobi. Obravnavane so različne izvedbe vbrizgalne šobe. Tako se lahko v modelu zbira med dvema različnima tipoma solenoidnih ventilov kakor tudi med uporabo dušilne ploščice ali hidravličnega ventila. Vplivi različnih elementov na karakteristike procesa vbrizgavanja so na podlagi numeričnih rezultatov na kratko analizirani.

Title:A mathematical model for numerical simulation of the fuel injection process in the ECD-U2 high pressure injection system
Abstract:In this paper a mathematical model for numerical simulation of the fuel injection process in the electronically controlled high pressure ECD-U2 fuel injection system for a Diesel truck engine is presented. The proposed mathematical model is based on the assumption that the injection pressure of a selected engine operating regime is kept constant. Keeping this is mind, attention is focused on the processes in the injector. Several configurations of the injector are considered. Consenquently it is possible to choose between two different types of solenoid valves, as well as between the return and the boot valve. The influence of different parameters on the injection characteristics is discussed briefly using the obtained numerical results.
Keywords:Diesel engine, injection process, numerical simulations, injection characteristics
