    • An injection valve has a magnetic actuator and an injector needle able to be moved axially by the magnetic actuator. To meter a fluid by the injection valve the magnetic actuator is activated for an individual metering process with at least one actuation signal with a first or second signal waveform. The two actuation signals differ from one another in that, on activation of the magnetic actuator by the actuation signal with the first signal waveform, less energy is transmitted to a magnet unit of the magnetic actuator than during activation of the magnetic actuator by the actuation signal with the second signal waveform. The magnetic actuator is activated by the actuation signal with the second signal waveform if an activation of the magnetic actuator by the actuation signal with the first signal waveform leads to an undesired premature closure of the injector needle.
    • 注射阀具有磁性致动器和能够由磁性致动器轴向运动的注射器针头。 为了通过注射阀计量流体,磁致动器被激活用于具有第一或第二信号波形的至少一个致动信号的单个计量过程。 两个致动信号彼此不同之处在于,在通过具有第一信号波形的致动信号激活磁性致动器时,与通过致动信号激励磁致动器的能量相比,较少的能量传递到磁致动器的磁体单元 与第二信号波形。 如果通过具有第一信号波形的致动信号激活磁性致动器导致喷射器针的不期望的过早闭合,则磁性致动器由具有第二信号波形的致动信号激活。

    • A first energy control unit has a pilot controller with an applied setpoint energy and outputs a pilot control signal, and a regulator outputting a regulator signal as a function of the setpoint energy and an actual energy of the piezo actuator. The energy control unit creates a control signal representative for a current threshold of a charge current, depending on the pilot control and regulator signals. Furthermore, there is a second energy control unit for another setpoint energy and another control signal. A power output stage sets a charge current for the piezo actuator as a function of the predetermined control signal and performs this for the predetermined time. A scheduling unit predetermines, for setting the setpoint energy, the control signal and the time to the power output stage, and for setting the another setpoint energy, the another control signal and the time to the another power output stage.
