    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: 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: The present invention relates to a method for detecting an angular position signal representing the rotary motion of a rotating part of an internal-combustion engine. The internal-combustion engine includes at least one combustion chamber. In addition, a speed sensor of the type mentioned initially is provided, the speed sensor outputting a rotation-measurement signal representing the rotary motion of a sensing wheel connected with the rotating part. At least one pressure sensor is also provided that outputs a pressure signal representing the pressure in a combustion chamber. The method according to the present invention has the following steps: Detect the pressure signal, detect the rotation-measurement signal, calculate a correction quantity that is a function, at the least, of the detected pressure signal and rotation-measurement signal, and determine the angular position signal by linking the detected rotation-measurement signal with the correction quantity. The core of the present invention is the identification and very good compensation of the sensing wheel error by performing a joint evaluation of the rotational-speed signal and the compression chamber pressure of one or more indicated cylinders.
