摘要： A delivery device for delivering liquid reducing agent includes a reducing agent tank. At least a delivery unit, at least one first compensation element, a reducing agent line and a metering unit together have an overall volume to be filled with a reducing agent and are configured for delivering, conducting and metering the reducing agent from the reducing agent tank. The at least one first compensation element is configured for reducing the overall volume when a negative pressure occurs in the delivery device. A method for compensating freezing of a reducing agent in a delivery device and a motor vehicle having a delivery device, are also provided.

摘要： A foil for producing a metal honeycomb or catalyst carrier body, has an average surface roughness of more than 0.3 μm (micrometers) on both surfaces in at least one measurement direction. Preferably, the foil is rolled and has an average surface roughness of more than 0.3 or 0.5 μm, especially approximately 0.6 μm, in the rolling direction and/or transverse thereto. The foil can have an oxide coating with a thickness between 60 and 80 or between 70 and 75 nm (nanometers) on both surfaces. Despite the roughness, an even thickness of the oxide coating with a tolerance of less than 10% or 5% is advantageous on both surfaces. The foil allows production of durable honeycomb bodies, especially for exhaust systems of internal combustion engines, requiring an exactly defined distribution and quality of compounds in the interior thereof. A honeycomb body and method of production using a foil, are also provided.

摘要： A delivery device for delivering a reducing agent from a reducing agent tank to an exhaust gas treatment device of an internal combustion engine, includes a partially rigid reducing agent line and a delivery pump disposed in the reducing agent line and having a delivery direction from the reducing agent tank to the exhaust gas treatment device. The delivery device has at least one vibration compensating device selected from the following group: an inflow compensating device upstream of the delivery pump in the delivery direction, an outflow compensating device downstream of the delivery pump in the delivery direction, a pump-internal compensating device within the delivery pump, and a structure borne noise compensating device on a fixing of the delivery pump. A motor vehicle having the delivery device is also provided.

摘要： An injector mount for completely accommodating at least one injector includes a housing having at least one injector chamber. The at least one injector chamber has a first opening and a second opening. The first opening of the injector chamber can be connected to a region of an exhaust line that conducts exhaust gas, and the second opening of the injector chamber can be closed repeatedly by a closure. An exhaust line having an injector mount is also provided.

摘要： A method for heating a delivery device for a reducing agent includes providing the delivery device with a return valve which is in an open position when an opening current is supplied to the return valve and which is in a closed position and operates as a heater when a heating current that is smaller than the opening current is supplied to the return valve. The return valve is preferably in heat-conducting contact with a metallic base plate of the delivery device.

摘要： A device for evaporating a urea-water solution includes a delivery duct for the urea-water solution. The delivery duct extends through at least a first zone and a second zone for the introduction of heat energy. The zones can be heated separately from one another and, in the second zone, the delivery duct initially has a meandering course in a second inlet region, and thereafter has a rectilinear course. A method for evaporating a urea-water solution includes pre-heating the urea-water solution in the first zone to a temperature in a range from 100° C. to 150° C. and evaporating the urea-water solution in the second zone at a temperature in a range from 420° C. to 490° C. In particular, this significantly reduces the tendency for such an exhaust-gas-external evaporator for a urea-water solution to become blocked. A motor vehicle is also provided.
