    摘要: Switching off a fuel pump of a fuel supply system for the internal combustion engine with the aid of a signal from a retardation sensor of the airbag in the event of a crash in which the motor vehicle is involved is known. To further enhance the safety of motor-vehicle occupants, a method is proposed for an internal combustion engine which has at least one fuel injection valve, a fuel supply system for the at least one fuel injection valve, and a sensor for detecting a crash. After the crash has been detected by means of the sensor, the fuel injection valve is brought into an open position, with the result that fuel is discharged from the fuel supply system of the fuel injection valve into a combustion chamber of the internal combustion engine. The method according to the invention is provided for internal combustion engines with at least one fuel injection valve.

    摘要: In a valve for the dosed discharge of fluids particularly a fuel injection valve for fuel injection systems of internal combustion engines, the valve includes in an valve housing at the front end of an injector housing a valve structure at a fluid discharge end of the valve housing and a stack of piezo elements disposed in the opposite end of the injector housing and a high pressure fluid passages leads to the fluid discharge end which is isolated from the area in which the stack of piezo elements is disposed and which is in communication with a low pressure drain passage such that the piezo elements are not exposed to the high pressure fluid. Isolation is obtained by a compensation cylinder movably disposed in an annular space between, and in sealing relationship with, the valve housing, the piezo stack being enclosed in a piezo guide tube which is sealingly connected to the valve housing.

    摘要: A piezoelectric actuator for media flowing around it having a piezo stack which is arranged within a deformable isolating material so as to be in direct contact therewith at least over certain regions. The isolating material is for its part enclosed by a fluidically closed actuator housing, which is formed by a housing shell which is delimited at its one end by a dimensionally stable actuator top and at its other end by a dimensionally stable actuator bottom. The actuator top and bottom are arranged on the active main surfaces of the piezo stack. To increase the service life, the housing shell is produced from a limp and/or elastic material and is disposed at a distance from the piezo stack. The length of the housing shell, measured along the surface line, corresponds at least to the maximum extent of the piezo stack and/or the housing shell can be stretched. accordingly.

    摘要: A method for evaluating an ion current signal of a self-igniting internal combustion engine, with the ignition shift being derived from the time shift of the local maximum in the curve of the ion current signal relative to an injection point in time. Similarly, continuous injection in a cylinder can be detected when the ion current signal is integrated and evaluated in terms of area and/or when the position and/or height of the maximum of the ion current signal are evaluated. Carbon formation can be detected by an evaluation of the time curve of the ion current signal following an injection. For example, the parameters of the main injection can be controlled as a function of an evaluation of the measured ion current following a preinjection. When a continuous injection is detected, injection can be suppressed at least in those cylinders in which continuous injection was detected.
