Abstract: 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.

Abstract: 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.

Abstract: An exhaust gas turbocharger for an internal combustion engine comprises a turbine in the exhaust line and a compressor, which is driven by the turbine and which is located inside the intake tract of the internal combustion engine. The turbine comprises a flow duct having a radial flow entrance cross-section, and a flow ring is provided that delimits the flow entrance cross-section. An adjustable vane is placed in the radial flow entrance cross-section for variably adjusting this flow entrance cross-section. The flow ring inside the housing of the exhaust gas turbine can be axially displaced between a contact position toward the vane and a position that frees a gap toward the vane.

Abstract: A gas bag module comprises a gas bag with a gas bag wall having a front wall serving as an impact surface for an occupant, where, in an inflated state of said gas bag, the front wall has a centric orifice as a transition to an indentation. The indentation is formed by restraining a center section of the gas bag wall during inflation and preventing the center section from moving freely. The orifice is surrounded by a stabilizer defined by a closed ring in a region of the orifice and the stabilizer is a part separate from the gas bag wall.

Abstract: A method for check the phase adjustment of a camshaft, in which the present phase angle of a variable phase camshaft can be detected reliably. A first value which corresponds to the actual noise level of the internal combustion engine is determined during a predetermined evaluation window and is compared with a second value, which corresponds to the actual noise level after phase adjustment of the camshaft, with the operation of the phase adjustment of the camshaft being assessed as a function of this comparison.
