摘要： A method is provided for operating an internal combustion engine 10 in overrun condition, which method includes the steps of: release of a monitoring of a control signal for a power actuator of the internal combustion engine when predetermined release conditions have been satisfied, which include the exceeding of a release rotary speed of the internal combustion engine; after the release, comparing a control signal for the power actuator of the internal combustion engine to a threshold value, and triggering an error response if the control signal exceeds the threshold value. The method provides that the release speed is varied as a function of the intervention of an idling speed control in the formation of the control signal. Also provided is a control unit which controls such a method.

摘要： A method is proposed for diagnosing the drive voltage for a piezoelectric actuator of an injector, in which the drive voltage is measured for the individual phases of the injection procedure. With respect to each control phase, a corresponding tolerance band is provided, which is set using the setpoint value of the drive voltage. The tolerance ranges are established as a function of operating and/or environmental conditions. If, for the individual drive cycles, the corresponding tolerance ranges are not reached, then, in response to repeated measurement, these erroneous measurements are counted. When a preestablished number for the erroneous measurements is exceeded, then an ongoing error is diagnosed. If, after a certain time, the number is not exceeded, then the counter is reset. In the case of an error, the error storage unit can be reset using a maintenance plug-in device during maintenance.
