Abstract
A method and a device for controlling a fuel injection system for an internal combustion engine of a motor vehicle, whereby the internal combustion engine has a common rail, a high-pressure pump, a flow control valve for controlling the fuel delivery rate of the high-pressure pump into the common rail and a control unit for triggering the flow control valve. The method comprises the steps of determining the prevailing fuel demand in the common rail as a function of the prevailing driving state of the vehicle and controlling the pulse duty factor and frequency of the triggering of the flow control valve as a function of the prevailing fuel demand determined in the common rail.
