Abstract: A clutch sensor system includes a clutch part that is rotatable about and axially displaceable along an axis of rotation, and a sensor device having at least one sensor element configured to detect a rotary movement parameter of the clutch part. A circumferential transmitter structure is disposed on a circumference of the clutch part, and has a first sub-structure and at least one second sub-structure that follow each other in alternating fashion in a circumferential direction. The sub-structures are separated by structure transitions that move past a detection area of the sensor element as the clutch part rotates, whereby the sensor device generates a sensor signal that includes information about the rotary movement parameter. A circumferential distance between successive structure transitions depends on an axial displacement of the clutch part, such that the sensor signal also includes information about the axial displacement position of the clutch part.

The torque sensor has a rotatable torque transmitter having magnets, which generate a magnetic field, and a magnetic flux unit for amplifying the magnetic field. The index elements and the magnetic flux unit are connected to one another in a rotationally fixed manner.

A measuring structure, e.g., a thermopile measuring structure as a series circuit made of thermocouple pairs, is implemented between the measuring diaphragm and the reference diaphragm for measuring a temperature differential between the measuring diaphragm and the reference diaphragm. First and second thermal contacts lie alternately on the two diaphragms.

Abstract: The quantitative determination of aging effects on motor oil is of great interest. According to a method, two variables of the motor oil are detected, one of the two variables being the viscosity and the other variable being the acid content of the motor oil. A first deviation of the detected first variable from a default value is then determined, and the second variable is estimated based on the deviation. By determining a second deviation of the estimated second variable from the detected second variable, the second deviation is determined as a measure of the aging effect on the motor oil. Since various aging effects influence the two variables in different manners, individual aging effects may be quantitatively determined in a targeted manner.

Abstract: A procedure to operate an internal combustion engine, whereby at least one fuel afterinjection is conducted, and a device to implement the procedure are proposed. An oil dilution signal is ascertained as a measurement for, for example, the volume of the oil dilution brought into the motor oil of the internal combustion engine by at least one fuel afterinjection. The fuel afterinjection, which is at least one in number, is, for example, so designed to introduce non-combusted fuel as combustible fuel into the exhaust gas area of the internal combustion engine, which reacts exothermally in the exhaust gas area to heat the exhaust gas treatment device.

Abstract: A method for operating a particulate filter disposed in an exhaust-gas region of an internal combustion engine and a device for implementing the method. Based on an oil signal provided by an oil sensor, an oil-consumption determination determines the oil consumption of the internal combustion engine. From the oil signal, an ash-load determination calculates a measure for the ash-load state of the particulate filter, which can be taken into account for the operation of the particulate filter, particularly in establishing a threshold value for the maximum permissible particulate-load state. Moreover, a filter replacement signal can be obtained from the ash-load state.
