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 piezoelectric actuator is proposed, having a plurality of piezoelectric elements that are stacked on top of each other. Piezoelectric layers between each of which an inner electrode having a polarity alternating within the layer structure is provided. Outer electrodes are present at two opposing lateral surfaces, through which the inner electrodes are supplied with an electric charge. From each outer electrode at least one conductive fuse bar is directed to these inner electrodes, preferably in the inactive region, for contacting each of these inner electrodes that are associated with the polarity. The fuse bar forms an electric resistance cross-section to the respective inner electrode with the respective contact surface. In case of high current flow, the respective fuse bar blows, thus forming a fusible cut-out.

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： A fuel injection valve for internal combustion engines having a valve body in which a bore is embodied, a valve seat face, at least one injection opening embodied on the end toward the combustion chamber of the bore, and at least one injection opening connecting the bore with the combustion chamber of the engine. A nozzle needle is longitudinally displaceably guided in the bore and on its end toward the combustion chamber it has a sealing face, which cooperates with the valve seat face and thus controls the at least one injection opening. The nozzle needle has a central longitudinal bore, in which an inner needle is disposed that is fixed immovably relative to the valve body. The nozzle needle is guided over at least part of its length on the inner needle, so that the nozzle needle is kept exactly centrally in the bore at all times.

摘要： The invention relates to a fuel injector for injecting fuel into the combustion chamber of an internal combustion engine, comprising a nozzle needle (1) which is able to perform stroke motions and by the stroke motion of which at least one injection opening can be exposed or closed, and further comprising a control valve (2) for controlling the stroke motion of the nozzle needle (1) in that, depending on the respective switch position of the control valve (2), hydraulic pressure applied in closing direction to the nozzle needle (1) in a control chamber (3) is altered, and further comprising a sensor array (4) for detecting the needle closing time. According to the invention, the sensor array (4) is arranged in the low-pressure area of the fuel injector in a space (5) which is sealed with respect to the fuel-conducting area (6). Sealing of the space (5) is effected by a membrane (7) made of a fuel-resistant, electrically conductive material, allowing the membrane (7) to also be utilized for implementing a ground connection.
