Abstract:
In this paper a mathematical model of a Common Rail Injector (CRI) fitted to automotive diesel engines is presented. The CRI model includes submodels of solenoid, working chamber and needle. It has been simulated using Matlab/Simulink software environment. CRI is a fully flexible fuel injection system in which quantity, timing and pressure of the injection are controllable separately. Also, the non-linearity in fuel compression is considered. The high fuel pressure is supplied by a pump while an ECU calculates and sends a signal to injector which opens and shuts a solenoid. The model results have been validated with experimental data.
