Abstract: A method for operating an exhaust gas purification system of a motor vehicle internal combustion engine is disclosed. The system has an SCR catalyst where a reducing agent containing ammonia is metered into the exhaust gas at a predeterminable metering rate which is produced from a base value and an adaptation factor which corrects the base value. A test procedure checks and, if appropriate, adjusts the adaptation factor where a first nitrogen oxide value is compared with a second nitrogen oxide value of the exhaust gas, where the first and the second nitrogen oxide value are determined by the same nitrogen oxide sensor disposed downstream of the SCR catalyst. The first nitrogen oxide value is determined when the metering of the reducing agent is switched off and the second nitrogen oxide value is determined when the reducing agent is metered at a test metering rate which can be predetermined.

Abstract: A method for producing a body of a passenger car is provided. A plurality of body components are connected to each other, the body components are provided at least in part with a plastic. The body is produced in a combined internal high pressure forming and injection molding process.
Abstract: A container, in particular for integrating into a tailgate of a motor vehicle, is disclosed. The container has a container lower part which is able to be attached to the tailgate and having a container cover which is able to be connected or is connected to the container lower part for the selective opening or closing of the container lower part. The container cover is connected to the container lower part via a joint arrangement by which the container cover is able to be arranged at at least two different distances to the container lower part such that a height of the container is able to be adjusted.
Abstract: A lighting unit for a passenger motor vehicle is disclosed. The lighting unit includes a housing having a lens fastened to the housing and having a sealing element supported on the housing which has a receiver to support a bumper of the passenger motor vehicle. The sealing element is fastened to the housing by a support element fastened to the housing.
Abstract: A motor vehicle parking lock device has at least one locking element for locking a parking lock piston in a positive-fit manner and a release unit having at least one electromagnetic actuator for releasing the parking lock piston. The release unit has a hydraulic and/or pneumatic actuator acting parallel to the electromagnetic actuator and which releases the parking lock piston at least in the event of a failure of the electromagnetic actuator.
Abstract: A motor vehicle steering column includes an inner jacket pipe that receives a steering spindle, which is received in a longitudinally adjustable manner in an outer jacket pipe held on a steering console and having a hollow cross-section. The steering column also includes a clamping device, by means of which the inner jacket pipe can be releasably secured in its adjusted longitudinal position relative to the outer jacket pipe. The outer jacket pipe has a recess at least over a longitudinal region, whereby its hollow cross-section can be altered by the clamping device.

Abstract: A membrane electrode assembly (MEA) for a fuel cell which exhibits enhanced reversal tolerance. In particular, a layer of iridium or an iridium compound, preferably metallic iridium or iridium oxide supported on TiO2, is provided on the anode to electrolyze available water and pass the majority of the current during a reversal of the fuel cell, thereby preventing damage to the MEA. The iridium or iridium compound is applied to an anode structure according to a predetermined pattern, with only part of the anode active area containing Ir. The parts of the MEA that do not contain Ir are not expected to suffer degradation from Ir cross-over, so that overall degradation of the cell will be diminished. Having less precious metals will also translate into less cost.
Abstract: A crossmember for the base region of a motor vehicle shell structure is disclosed. The crossmember is a light metal or a light metal alloy, preferably aluminum or an aluminum alloy, preferably magnesium or a magnesium alloy, at least in regions and is produced at least in regions by forging.
Abstract: An arrangement of a side door on a body of a motor vehicle is provided. The side door is held on the body in a closed position that closes a door opening corresponding to the side door with respect to the transverse direction of the vehicle with at least regional overlapping with a side sill of the body. The side door has a reinforcing element, with which the side door can be supported on the side sill in the event of an application of force, caused by an accident, acting on the side door from the outside in at least substantially in the transverse direction of the vehicle.
