Abstract
In a fuel injection system of an internal combustion engine fuel is delivered into a fuel rail by a high-pressure pump. The quantity of the delivered fuel is influenced by a quantity control valve operated by an electromagnetic operating device. At least one parameter of a braking pulse of the electromagnetic actuating device depends on an efficiency of the electromagnetic actuating device and/or on a supply voltage of a voltage source and/or on a temperature, in particular of a component of the fuel injection system or of the internal combustion engine.
