A method for the operation of a particulate filter in an exhaust aftertreatment system of a combustion engine () with the following steps: set up () a pressure difference model, which models a measured pressure difference (&#x394;p) which drops across the particulate filter () as a function () of a volume flow ({dot over (V)}) through the particulate filter () with an offset value (a, C); measure () multiple measurement values () for the pressure difference (&#x394;p) at different volume flows ({dot over (V)}) and solve () the pressure difference model as a function of the pressure difference (&#x394;p), whereby the offset value (a, C) is also determined.

A cable passage for sealing and for electrically contacting an exhaust-gas sensor includes: a protective sleeve; and at least one connecting cable which is run out of the protective sleeve on at least one front side of the protective sleeve. At least one cross section of the space existing between the protective sleeve and the at least one connecting cable is filled with a thermoplastically workable fluoropolymer-containing material.

Sealed cable passage for an exhaust-gas sensor

A contact element for contacting a contact point formed on a body includes: an element section on the contact point side for a force-locking connection to the contact point, an element section on the connection side for connection to an electrical connection conductor, and an intermediate section which connects the two element sections to one another for compensating for thermal expansions. At least the element sections on the contact point side and on the connection side are made of different integrally bonded materials having material properties which are adapted to the functionality of the corresponding element section.

Contact element and method for manufacturing same

A gas-measuring probe for determining a physical characteristic of a measuring gas, in particular the concentration of a gas component or the temperature or pressure of the measuring gas, which includes a sensor element accommodated in a housing, at least one connection cable for the sensor element having an electrical conductor, which is enclosed by an insulation sheath and contacts the sensor element, and a cable channel sealing the housing end, which has at least one axial cable feedthrough through which the connection cable is guided out of the housing. To achieve long-lasting sealing at the cable-exit end of the housing even at higher temperatures, the insulation sheath of the connection cable is at least regionally welded to the cable wall of the cable feedthrough. To this end, a tube made of a material that fuses with the insulation sheath and the cable channel when heated is slipped over the cable section of the connection cable lying inside the cable channel.

A sensor unit for determining a physical sensor parameter of a measuring gas, in particular an oxygen concentration in an exhaust gas of an internal combustion engine is provided, which includes a sensor housing and at least one connection cable having an electrically insulating cable sheathing, for the transmission of energy and/or the sensor parameter, the sensor housing having at least one cable opening for the connection cable and at least one sealing element for sheathing and sealing the connection cable, the cable having better sealing than the related art and/or the ability to resist higher temperature loading. According to the invention, this is achieved by at least partially forming the sealing element as tube.

Sensor unit having a connection cable

A gas sensor, whose purpose is to determine a physical property of a measuring gas, e.g., to determine the concentration of a gas component or the temperature of an exhaust gas. The gas sensor includes a sensor element arranged in a metal housing which is sealed by at least one sealing element arranged in a metal receptacle. The metal receptacle is affixed to the housing. The sealing element surrounds the sensor element in a centered position along its longitudinal extension L or on its half facing the measuring gas.

Gas sensor and method for production thereof

A detecting element is described, in particular a gas sensor for detecting the concentration of a gas component in a measuring gas, including a sensor element which is exposable to the measuring gas and has a connecting end section which is contacted by connecting cables and is exposed to a reference gas atmosphere. The end section is accommodated in a protective sleeve having a radial opening over which a gas-permeable diaphragm covering the at least one radial opening is provided, the diaphragm, in turn, being engaged by a clamping sleeve having at least one radial opening. To avoid the axial penetration of liquids between the clamping sleeve and the diaphragm, which would cause the detecting element to malfunction, the clamping sleeve is caulked axially above and below the radial openings. Both caulking zones are designed in such a way that the diaphragm is compressed with increasing force from the inner caulking edges facing each other to the outer caulking edges facing away from each other.

A sensing element for determining a physical property of a gas mixture, in particular the exhaust gas of internal combustion engines, includes a sensor element, arranged in a housing and connected to at least one electrical cable, as well as a molded piece, which seals the housing and is made of an elastically deformable material, which encloses the at least one cable in a gas-tight manner by radial compression. To ensure the gas-tightness of the cable feed-through also under a higher temperature load, which results in decreased elasticity of the molded piece, a spring element is arranged inside the molded piece, which is able to be tensioned by the radial compression and in the tensioned state generates a force component that acts on the cables in a radial direction.

A method for precision-grinding a bezel at the inlet of a bore of a workpiece, comprising the following steps: a. generating a bezel at the inlet of the bore of the workpiece by grinding the workpiece at the inlet of the bore with a first grinding tool into a first shape defining an angle correspondingly slightly greater than a desired nominal angle; b. honing the bore to generate a honed bore; and c. again grinding the bezel to its nominal shape by means of a second grinding tool, while simultaneously guiding the second grinding tool in the honed bore by means of a pilot.
