    摘要： In a method and a device for controlling an internal combustion engine (1), the accuracy of the detection of knocking in an internal combustion engine (1) can be increased by determining a reference ignition advance angle for an actual operating point of the internal combustion engine (1) at which the efficiency of the engine is a maximum. An actual ignition advance angle at which the internal combustion engine (1) is to be operated at the actual operating point is determined. Signals from a knocking sensor (14) are detected, allowing conclusions to be drawn concerning a knocking event in a combustion chamber (30) of the internal combustion engine (1). To detect knocking, only the signal values which lie within a predetermined evaluating interval are used, wherein the position of the evaluating interval is determined depending on the difference between the reference ignition advance angle and the actual ignition advance angle.

    摘要： An exhaust-gas turbocharger for an internal combustion engine has a turbine in the exhaust-gas tract and a compressor, driven by the turbine, in the intake tract, the turbine having a flow channel with a radial flow-inlet cross-section and a semi-axial flow-inlet cross-section, and a flow ring being provided which limits the two flow-inlet cross-sections. The turbine is furnished with variable turbine geometry for the changeable adjustment of the flow-inlet cross-section. To improve efficiency, the position of the flow ring in the housing of the exhaust-gas turbocharger is variably adjustable.

    摘要： A method and current sensor arrangement for measurement of a primary current in a primary conductor which is magnetically coupled to a secondary conductor via a ferromagnetic core, with a voltage of a specific amplitude being applied to the secondary conductor, such that a secondary current flows for remagnetization of the ferromagnetic core, and the secondary current is measured during the remagnetization of the core, in order to obtain a first measured value. The voltage polarity is then reversed such that a secondary current flows for renewed remagnetization of the ferromagnetic core, and the secondary current is measured during the remagnetization of the core, in order to obtain a second measured value. The primary current is calculated as a function of the first and of the second measured value, with the polarity reversal being carried out at least once at a time which occurs before that time at which the ferromagnetic core reaches its saturation magnetization.
