Abstract:
A metal sheet having a microstructure relieved of notching, a carrier body having a plurality of sheets, and an exhaust system having the carrier body, are distinguished by a particularly long useful life in an automobile. Moreover, it is possible to bring about flow profiles coordinated exactly with the respective fields of use, so that a particularly efficient or extremely adaptable carrier body for purifying the exhaust gas of automobiles is provided.
Abstract:
A tank for a reducing agent includes a tank wall having an outer side and an interior at least partially delimited by the tank wall. A sensor is disposed at the tank wall and has a first electrical contact and a second electrical contact. The first electrical contact and the second electrical contact communicate in an electrically conductive manner with the interior, extend through the tank wall from the interior to the outer side of the tank wall and are disposed at a first spacing of less than 5 cm from one another. A motor vehicle having the tank is also provided.
Abstract:
A method for metering a reducing agent from a metering device to an exhaust gas treatment device includes initially determining at least one operating parameter of the metering device. An injector pressure at an injector for feeding the reducing agent into the exhaust gas treatment device is then calculated from the at least one operating parameter. Then, an opening time for the injector is calculated, in which at least the injector pressure determined in step b) is used. The injector is then opened for the opening time calculated in step c). A method for setting up or configuring a control unit for a metering device and a motor vehicle having a metering device are also provided.
Abstract:
A process for producing a structure in a smooth sheet-metal strip includes multiple process steps. In a first step, a first section of a smooth sheet-metal strip is fed to a first tool and a second section of the sheet-metal strip is fed to a second tool in a direction of advance. Then the sheet-metal strip is stopped. A sheet-metal machining of the first section of the sheet-metal strip is carried out using the first tool. A sheet-metal machining of the second section of the sheet-metal strip is carried out using the second tool, with the first feeding step being carried out simultaneously. An apparatus is provided for producing a sheet-metal strip of such a complex structure, which produces the structure with a very high degree of accuracy even when the materials properties differ.
Abstract:
A configuration for purifying or cleaning an exhaust-gas flow of an internal combustion engine includes at least an ionization device, an agglomeration device, and a (catalytically active) radial honeycomb body around a duct. The exhaust-gas is diverted from the duct into the radial honeycomb body, while the agglomerated particles are caught in a particle separator of the duct. A method for purifying or cleaning an exhaust-gas flow of an internal combustion engine and a motor vehicle including an exhaust system having the configuration, are also provided.
Abstract:
A device for exhaust-gas treatment includes at least one housing with an inner surface and at least one sensor foil disposed in the housing. The sensor foil is formed at least with a sensor element and a conductor element. The sensor foil is also provided with an edge up to which the conductor element extends and which bears against the inner surface of the housing. The housing also has an opening for contacting of the conductor element. The opening is surrounded on the inner surface by an electrical insulating layer.
Abstract:
A method for removing soot particles from an exhaust gas of an internal combustion engine, especially of a diesel engine, includes feeding the exhaust gas through a collecting element through which the exhaust gas can pass freely but which is provided with a plurality of deflections and/or zones of swirl and calming or stabilization. At least a proportion of the particles are held or swirled around in the collecting element until there is a sufficient probability of reaction with nitrogen dioxide and a majority of the collected particles have been removed. A collecting element has flow channels through which the exhaust gas can pass freely. However, the flow channels are configured in such a way as to form deflections or zones of swirl and calming or stabilization. A system having the collecting element is also provided.
Abstract:
A honeycomb body includes a housing and a plurality of layers with a curved profile and a predetermined length. Each layer includes at least one at least partially structured metal foil forming a multiplicity of passages with a passage cross section. A majority of the layers have different lengths than one another. A process for producing a honeycomb body, a process for treating exhaust gas, and an exhaust gas assembly, are also provided.
