    摘要： An injection system for injecting fuel has an actuator, a pilot valve with a valve mushroom, and a supply throttle. The control chamber encompasses a control piston, a first discharge throttle, a first sealing edge for forming a first sealing seat along with the valve mushroom, a second sealing edge of a piston chamber with a valve piston, the second sealing edge forming a second sealing seat along with the valve piston during a maximum actuator working lift for sealing the piston chamber and the valve chamber from each other; and a second discharge throttle connecting the piston chamber to the low-pressure zone between the first and the second sealing edge, wherein d1>d2>d3, d1 are the minimum diameter of the first discharge throttle, d2 being the minimum diameter of the second discharge throttle, and d3 being the minimum diameter of the supply throttle.

    摘要： In a method for determining a vibration-optimised adjustment of an injection device of an internal combustion engine, for each cycle of the internal combustion engine, a plurality of individual injections per cylinder is carried out by the injection device, each of which is defined by a relative injection moment and an individual injection quantity. A temporal course of a resulting pressure influenced by pressure waves is determined in a fuel guiding part, and the above-mentioned adjustment is determined by variation of the injection moment of at least one individual injection and/or the individual quantity, such that the adjustment is characterised by a temporal variation of the resulting pressure, which is reduced by an at least partially destructive interference between the cited pressure waves. A corresponding device can determine a vibration-optimised adjustment of an injection device, and an internal combustion engine may have such a device.

    摘要： A method and system for controlling an injection valve has the following steps: recording a voltage curve of a voltage present at a piezoelectric actuator of the injection valve and a time characteristic curve of an electric charge which is shifted in a circuit with the piezoelectric actuator during a reference injection, computationally determining a force curve of a force applied by the piezoelectric actuator to a moving closing element of the injection valve during the reference injection from the voltage curve and the time characteristic curve of the electric charge, determining a location of a maximum of the force curve,—specifying an activation time instant and/or an activation duration and/or an activation pulse intensity for at least one subsequent injection as a function of a time offset between an activation time instant selected for the reference injection and the maximum of the force curve.
