A fuel injection device includes a nozzle needle, an actuator for actuating the nozzle needle, a force sensor for detecting a force applied by the actuator, and a control unit which is connected to the force sensor. The force sensor supplies signals to the control unit and the control unit is designed for determining a position of the nozzle needle and for precisely determining an injected fuel quantity, based on the supplied signal.
