摘要： 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.

摘要： A method for operating an internal combustion engine is described. A base controlled variable for influencing an actual value of an operating variable of the internal combustion engine is ascertained. The actual value of the operating variable is compared to a setpoint value of the operating variable. A correcting variable is ascertained as a function of the comparison. A controlled variable is ascertained as a function of the base controlled variable and as a function of the correcting variable. An actual value of a state variable of the internal combustion engine is ascertained. A start point in time of a time interval of a critical state change of the internal combustion engine is ascertained as a function of the ascertained actual value of the state variable. The controlled variable is essentially ascertained from an intermediate controlled variable and a correcting variable following the start point in time.

摘要： The invention concerns a procedure for determining the composition of a fuel mixture from a first fuel and a second fuel or for determining the quality of a fuel for operating a combustion engine with at least one cylinder pressure sensor in at least one cylinder of the combustion engine for determining the pressure history during a combustion process and a cylinder pressure based motor regulation for regulating the load and the combustion situation of the combustion engine. It is thereby provided that the determination of the composition of the fuel mixture or the quality of the fuel takes place with the aid of regulator information of the cylinder-pressure-based motor regulation. The procedure enables the continuing determination of the composition of the fuel mixture and the quality of the fuel at cylinder-pressure-based motor regulations without additional components as for example an ethanol sensor.

摘要： A method for recognizing uncontrolled combustions in an internal combustion engine which occur independently of the ignition by a spark plug. The pressure oscillations in the combustion chamber triggered by the combustion are detected and evaluated. To allow identification at any time of an uncontrolled combustion prior to ignition by the spark plug and/or prior to the normal combustion initiation for a given ignition point, the rotational speed of a crankshaft of the internal combustion engine which is influenced by the pressure oscillations, is evaluated.
