    摘要: The invention relates to a method for controlling an injection of an internal combustion engine. The invention provides that after the internal combustion engine is started, the injection and/or the ignition is carried out according to a signal of an absolute position sensor device, particularly according to an absolute position sensor of a camshaft or according to an absolute position sensor of a crankshaft and to an angular range sensor. When a synchronization signal is detected by a sensor wheel of the crankshaft, the following control processes are carried out according to the synchronization signal, i.e. according to the position of the crankshaft. The inventive method is advantageous in that immediately after the internal combustion engine is started, a relatively precise signal for controlling the injection and/or the ignition is available. This enables a more precise combustion shortly after the internal combustion engine is started.

    摘要: The invention relates to an actuator device which holds an actuator, for actuating a gas exchange valve of an internal combustion engine for instance, in an end position by means of a coil. The aim of the invention is to switch said actuator device into the other end position in time. To this end, the impingement of the coil with voltage is stopped a certain period of time tk before the moment when the actuator is released from the end position. The period of time tk is selected according to the supply voltage of the actuator device and/or of the coil current during holding in the end position. It is possible to adapt the period of time tk.

    摘要: The invention relates to a control device which comprises a magnetic actuator (1), a final controlling element (2), a control unit (3) and a measuring device (4). The magnetic actuator (1) has a coil (10), a core (11), a spring (12) and an armature (13). The actuator (1) is connected to the final controlling element (2). The measuring device (4) determines an inductance value L of the coil (10) and produces in relation to the inductance value L a first control signal which is used to set at a hold value a theoretical value for the current through the coil (10). The current through the coil (10) is adjusted by the control unit (3) to the theoretical value when there is a pulse signal P.
