Zusammenfassung:The invention relates to a method for controlling a fuel injector (100) comprising a valve needle (110) which is movable by an armature (130) that engages a stop (120) on the valve needle (130), in order to inject fuel into an internal combustion engine; in said method, an additional armature-lifting energization pulse that decelerates a movement of the armature (130) is applied to an electromagnetic coil (140), which cooperates with the armature (130), between a first and a second fuel-injecting energization pulse applied to the electromagnetic coil (140) to inject fuel. 本发明涉及种用于操控燃料喷射器(100)的方法,所述燃料喷射器包括阀针(110),所述阀针能够借助于作用在构造在所述阀针处的止挡部(120)上的磁衔铁(130)被运动,用以将燃料喷射到内燃机中,其中,在与所述磁衔铁(130)共同作用的磁线圈(140)的第与第二喷射-通电之间进行所述磁线圈(140)的附加的、制动所述磁衔铁(130)的运动的衔铁行程-通电,所述第和所述第二喷射-通电分别用于喷射燃料。
