20080264158 | Method for Determining Oil Dilution in a Internal Combustion Engine Featuring Post-Injection - 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. | 10-30-2008 |
20090211342 | Method for the Quantitative Determination of an Aging Effect on Motor Oil - 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. | 08-27-2009 |

20100085068 | SENSOR DEVICE FOR DETECTING ELECTRICAL PROPERTIES OF A FLUID - The sensor device for detecting electrical properties of a fluid under high pressure has: a pressure-tight housing, whose cavity is connectable to a high pressure line via an opening, a sensor for electrical properties, which is situated in the cavity, glass feedthroughs, which electrically connect the contacts on an external surface of the housing to the sensor. | 04-08-2010 |
20110110394 | Microstructured sensor for the detection of IR radiation - A microstructured sensor for detecting IR radiation includes: one measuring channel having a measuring diaphragm, on which a first sensitive detector surface is implemented for the absorption of a first IR radiation; and one reference channel having a reference diaphragm, on which a second sensitive detector surface is implemented for the absorption of a second IR radiation. 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. | 05-12-2011 |
20110308304 | LIQUID SENSOR - A fluid sensor includes a metal housing body, which has a box and a flanged ring circumferentially surrounding the box. A housing jacket is formed from plastic material and disposed on an exterior side of the housing body. A sealing ring, which is situated circumferentially on top of the flanged ring, subdivides the housing jacket into two sections that are insulated from each other. | 12-22-2011 |
20120152034 | Sensor system - A sensor system has a rotational angle sensor for detecting a rotational angle and a torque sensor for detecting a torque. The rotational angle sensor has a rotatable rotational angle transmitter having index elements. 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. | 06-21-2012 |
