Abstract:
A method and system for actively controlling the fuel pressure in the fuel rails of a fuel injection system is disclosed for providing wideband fuel rail control. An active pressure control circuit controls the pressure control valve over the entire range of engine operating conditions and in the frequency domain. Implementation of a closed-loop feedback control is effective for attenuating fuel pressure fluctuations in the fuel rail assembly.
