摘要： A method of producing a laminated core of a stator of an electric motor, includes at least one laminated core of a stator formed by stacked sheet-metal laminates, which have mechanical individual poles and of poles connected in the circumferential direction of the stator, at least one pole shank and at least one pole shoe facing a rotor. The sheet-metal laminates are configured with indentations and protrusions and, as a result, the sheet-metal laminates form the laminated core of the stator by interengagement of the indentations and protrusions. The mechanical poles of the laminated core of the stator have windings, and webs are provided between the poles to connect the connected mechanical poles in the circumferential direction. The axial set-up of the sheet-metal laminates of the laminated core of the stator has a predeterminable alternating succession of poles with a connecting web and poles without a connecting web.

摘要： A method for operating a self-igniting, air-compressing internal combustion engine, in which the engine is supplied with fuel by an injection system that has a high-pressure fuel reservoir, which is supplied with fuel by a high-pressure fuel pump and outputs fuel to electrically controlled injection valves. A control unit is provided, which detects the operating mode of the engine and upon occurrence of an overrunning mode allows a pressure increase in the high-pressure fuel reservoir. On resumption of normal operation, the drive of the high-pressure fuel pump is then interrupted, and the engine is supplied from the fuel previously stored at elevated pressure, until a lower limit value of the high pressure fuel is attained.

摘要： A method for learning and determining a minimum injector-specific electric actuation duration for at least one fuel injector of an internal combustion engine of a motor vehicle. Starting with a predefined electric actuation duration which definitely does not result in an injection, the electric actuation duration is gradually increased in each engine stop and/or in each engine start in successive engine stops and/or in successive engine starts of the internal combustion engine up to an actuation duration in which an injection with a combustion occurs, and then this actuation duration may be determined as the minimum electric actuation duration. The invention also relates to a corresponding device.

摘要： In an internal combustion engine, fuel is injected directly into a combustion chamber by an injector that has a piezoactuator. An electrical charge conveyed to and/or removed from the piezoactuator is ascertained by a method that is calibrated at least once during an operating time span of the internal combustion engine. To allow the calibration to be carried out or performed as often as possible, the method for ascertaining the electrical charge transferred to and/or removed from the piezoactuator may be calibrated during at least one triggering off-time (dtK) of the piezoactuator while the internal combustion engine is operating.

摘要： A method for operating a fuel injection system for an internal combustion engine is provided, in which monitoring is performed as to whether an overlapping occurs between a time interval in which one piezoelectric element for injecting fuel into a cylinder is to be charged or discharged, and a time interval in which a different piezoelectric element for injecting fuel into a different cylinder is to be charged or discharged. The monitoring is performed as to whether, in the context of a lower-priority injection, the charging or discharging occurs within a predefined time interval around the point in time of a charging or discharging of a higher-priority injection, the spacings of time-related charging and/or discharging edges (edge overlaps) being determined during operation of the fuel injection system, and the magnitude of the shift and/or shortening of the lower-priority injections with respect to the higher-priority injections being determined therefrom.
