    摘要: A method for operating a valve actuated with the aid of an actuator, in particular, an injection valve of an internal combustion engine of a motor vehicle, where the actuator is activated using an activation signal characterizing a desired opening duration of the valve. The activation signal characterizing the desired opening duration is corrected as a function of a valve delay time, in order to obtain a corrected activation signal for activating the actuator; the valve delay time representing a temporal deviation between the activation signal and an actual change of an operating state of at least one component of the valve, in particular, of the valve element of an electromagnetic actuator, or of a valve needle.

    摘要: A method for operating a fuel injection system of an internal combustion engine is described. The fuel injection system has an injector for metering fuel into a combustion chamber of the internal combustion engine. The injector has an actuator, a control valve and a nozzle needle. In the method, the actuator is supplied a voltage and/or a current during an activation period. The control valve is set into a lifting motion by the actuator. The injector is opened and closed by the nozzle needle, using the lifting motion of the control valve. A further time period is ascertained. The further time period ends at the closing time of the nozzle needle. A function is ascertained, which links the activation period to the further time period. A shortest activation period, for which the nozzle needle opens and produces an injection, is ascertained with the aid of the function. An opening delay period (do1) of the nozzle needle is ascertained as a function of the shortest time period.

    摘要: The invention relates to a fuel injector having a magnetic assembly, a magnetic core, and a magnetic coil. The magnetic assembly is accommodated in a magnetic sleeve. The magnetic sleeve is provided with feedthroughs for electric contacting pins of the magnetic coil. Elastic sealing elements are inserted into the feedthroughs of the magnetic sleeve such that a pretensioning force acting in radial direction is applied to the contacting pins of the magnetic coil in the mounted state.

    摘要: An arrangement is proposed for forming a piezoelectric actuator, which has at least one piezoelectric element that in each case consists of a multi-layer structure of piezoelectric-layers, wherein internal electrodes arranged between the piezoelectric-layers in the direction of the build-up of the layers of the piezoelectric element, have an electrical voltage of different polarity alternately applied to them. Around the piezoelectric element, or in the case of multiple piezoelectric elements positioned in series in the activation direction, around the piezoelectric elements, and at least partially around the actuator head and the actuator foot there is arranged a covering system made from at least one layer of an insulating material. The at least one layer encloses the joints between the piezoelectric element or elements and the actuator head and the actuator foot, forming a seal.

    摘要: A common rail fuel system essentially comprising at least one rail, at least two injectors, and a respective supply line of a definite length between the rail and each injector. In order to prevent oscillation-generated movements of one supply line from being transmitted to the adjacent supply lines, the respective adjacent supply lines are embodied with different natural frequencies as a result of the supply lines of a rail being of different dimensions, for example different lengths.
