Abstract :
This paper demonstrates the viability of frequency modulation of discrete voltage pulses via feedback loops as a means of control for an electronically actuated fuel injection system. Specifically, this study targets the effectiveness of such control with regards to the Hydraulically actuated Electronically controlled Unit Injector (HEUI). A more accurate model for electromechanical actuator (EMA) using solenoid has been implemented together with models of other subsystems. Significant improvements have been made to the existing MATLAB/Simulink modeling approach in order to implement a higher degree of system control.
