    摘要: The invention relates to an injection valve, comprising a control chamber (15) with a control piston (16) that is functionally linked with a nozzle needle (35). The control chamber (15) is linked, via an inlet throttle (13), with pressurized fuel, and with an outlet throttle (14) with a valve chamber (9). A servo valve (5) is disposed in the valve chamber (9), said servo valve opening a connection between the valve chamber (9) and a return element (40) depending on its position. The inventive injection valve further comprises a bypass throttle (12) that is interposed between the fuel feed line and the valve chamber.

    摘要: In a method and a device for operating an injection valve, a relevant time (t_ACT) is determined during a catch phase (PH_CATCH) when the electromagnetic actuator reaches a predetermined fraction value of the electric current, which value is smaller than a maximum current value, and a fraction of interval (T_FRAC) since the start of the respective catch phase (PH_CATCH) is determined depending thereon and the injection valve is diagnosed depending on the fraction of interval (T_FRAC) and the predetermined minimum and maximum threshold interval values (THD_T_MIN, THD_T_MAX).

    摘要: 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.

    摘要: In a method for determining a control parameter for a fuel injector of an internal combustion engine, the problem of enabling more precise determination of the control parameter, even if the fuel pressure (FUP) present on the fuel injector varies, is solved in that the fuel pressure (FUP) present on the fuel injector during the injection (I1, I2, I1′, I1″) is concluded while allowing for the time of the fuel pressure value detection and/or the crankshaft angle position of the internal combustion engine during the detection of the fuel pressure value, and that the control parameter is determined based on the fuel pressure (FUP) that was concluded.
