Patent number: 10066526Abstract: An exhaust gas line section, through which an exhaust gas can flow, includes a flow guiding structure, a feed unit configured to supply a liquid additive to the exhaust gas, and a permeable impingement structure, the flow guiding structure, the feed unit, and the permeable impingement structure being positioned one behind the other in the flow direction. The feed unit and the flow guiding structure are arranged and configured such that an impingement region of the liquid additive on the impingement structure overlaps the center of gravity of a flow distribution of the exhaust gas flowing through the impingement structure.Type: GrantFiled: January 27, 2014Date of Patent: September 4, 2018Assignee: Continental Automotive GmbHInventor: Klaus Mueller-Haas

Patent number: 9726059Abstract: An exhaust system includes at least one exhaust gas purification component, at least one exhaust line, at least one connecting device for connecting the exhaust system to an internal combustion engine of a motor vehicle and at least one fastening element for additionally fastening the exhaust system to the motor vehicle. The purification component can oscillate at a first resonance frequency range of less than 150 Hz in a fastened state. The purification component can oscillate due to vibrations of the engine at least when the engine is started or switched off. This, in particular, allows ash residues to be removed from a purification component during starting of the motor vehicle, so that maintenance expense for the purification component is reduced and effective operation thereof is possible over the long term. A motor vehicle having an exhaust system and a method for operating the motor vehicle are also provided.Type: GrantFiled: April 1, 2013Date of Patent: August 8, 2017Assignee: EMITEC Gesellschaft fuer Emissionstechnologie mbHInventors: Wolfgang Maus, Rolf Brueck, Klaus Mueller-Haas

Patent number: 9617895Abstract: A device includes a pipeline section for an exhaust gas flow. The pipeline section has an inlet end, an outlet end, a rectilinear section and a protuberance having an opening for installing a metering device for a liquid additive (in particular urea/water solution) in the rectilinear section. The protuberance has a height and an extent and the extent is at least twice as large as the height. At least one respective disk-shaped honeycomb body is disposed at each of the inlet end and the outlet end. A central axis of the opening is oriented toward one of the disk-shaped honeycomb bodies. A motor vehicle having the device is also provided.Type: GrantFiled: September 2, 2014Date of Patent: April 11, 2017Assignee: EMITEC Gesellschaft fuer Emissionstechnologie mbHInventors: Klaus Mueller-Haas, Rolf Brueck
