摘要： A reciprocating piston internal combustion engine includes: a sensor system on a gas exchange valve which has a valve head situated at a first end of a valve stem; a lever element which engages at a second end of the valve stem and which is designed to actuate the gas exchange valve by displacing the valve head; a detection element which, upon actuation of the gas exchange valve, is displaced along a displacement path; and a sensor device configured to ascertain a position of the detection element. The sensor device is situated in such a way that the detection element, during a displacement along a portion of the displacement path, moves predominantly in a movement toward the sensor device or away from the same, thereby providing a measurement of valve timing of the gas exchange valve.

摘要： A sensor device for acquiring at least one rotational property of a rotating element, particularly a rotational speed of a compressor wheel of an exhaust-gas turbocharger, includes at least one magnetic field generator for generating a magnetic field at the location of the rotating element, at least one magnetic sensor, e.g., a coil, for acquiring a magnetic field generated by eddy currents of the rotating element, and at least one pole pin. The pole pin is elongated at its end facing the rotating element and includes a section that is not enclosed by the magnetic sensor. The sensor can be installed as a plug sensor in a blind-end bore in the housing of the exhaust-gas turbocharger.

摘要： A sensor system for determining at least one rotation characteristic of an element rotating around at least one rotation axis. The sensor system includes at least one sensor wheel, which is connectable to the rotating element, the sensor wheel having a sensor wheel profile. The sensor system also includes at least one position sensor and at least one phase sensor. The sensor system further includes at least one digital interface and at least one incremental interface, the sensor system being configured to output at least one absolute position signal generated with the aid of the position sensor via the digital interface and to output at least one incremental signal generated with the aid of the phase sensor via the incremental interface.
