A device and a method for actuating an injector in a fuel-injection system of an internal combustion engine are described. Using a first calibration method and based on a control parameter, an injector parameter which characterizes the injection process is determined. Starting from this injector parameter, a first feature is determined for calibrating the injector. A second calibration method determines a second feature for calibrating the injector, based on an engine parameter. The first calibration method is monitored on the basis of the second feature.

Method and device for actuating an injector in a fuel injection system of an internal combustion engine

A method for operating an internal combustion engine in which a speed-based feature of the internal combustion engine, which is correlated with an indicated mean effective pressure of the fuel, is determined during the warm-up of the internal combustion engine and an ideal fuel quantity, which is to be injected into at least one combustion chamber of the internal combustion engine during the warm-up, is ascertained therefrom.

Method for operating an internal combustion engine

In a method for operating an injection valve, in particular a fuel injector of an internal combustion engine of a motor vehicle, one component of the injection valve, particularly a valve needle, is disposed in a manner allowing movement relative to other components of the injection valve, and preferably is able to be driven at least partially by an actuator. A structure-borne-noise signal is detected by a structure-borne-noise sensor, and the structure-borne-noise signal is evaluated in order to infer an operating state of the movably disposed component.

Method and control unit for operating an injection valve

A method for setting a combustion in a combustion engine, particularly in a diesel engine, having the following steps of generating a manipulated variable, particularly a point of injection (PI), as a function of a combustion feature (MFB50%), the combustion feature (MFB50%) representing a condition in cylinder, especially a pressure characteristic in the cylinder, and setting the combustion in cylinders of the combustion engine with the aid of the manipulated variable, the manipulated variable further being generated as a function of a correction value (CV), which is determined as a function of combustion information (dQ) that provides an indication about the quality of the combustion.
