Patent number: 8033101Abstract: An exhaust-gas system has an exhaust-gas pipe for guiding an exhaust-gas flow and an injection nozzle mounted to the exhaust-gas pipe for injecting reducing agent into the exhaust-gas flow. Downstream of the injection nozzle, the exhaust-gas pipe branches into at least two exhaust-gas lines. A fluid divider, formed with a front face that faces upstream into the gas flow, is disposed between the injection nozzle and the branching. The front face is oriented with respect to the cross section of the exhaust-gas pipe and the injection nozzle, such that the exhaust-gas flow and the medium are divided among the exhaust-gas lines in a predefined dividing ratio.Type: GrantFiled: March 26, 2008Date of Patent: October 11, 2011Assignee: Faurecia Abgastechnik GmbHInventors: Bernd Amon, Herbert Albert

Patent number: 7793490Abstract: An exhaust gas system for diesel vehicles has a first exhaust line and a second exhaust line that can be connected at the exhaust end to an engine. The first and second lines with their ends pointing downstream are connected to an SCR catalytic converter and a device with which a reducing agent can be introduced into the exhaust gas at a location situated upstream from the SCR catalytic converter. An injection unit for the reducing agent is provided only on the first exhaust line, and a mixing device is provided upstream from the SCR catalytic converter so that the exhaust lines open into the mixing device, where the exhaust gas stream of the first exhaust line to which the reducing agent has been added becomes mixed with the exhaust gas stream from the second exhaust line that is free of reducing agent.Type: GrantFiled: September 26, 2007Date of Patent: September 14, 2010Assignees: Faurecia Abgastechnik GmbH, Audi AGInventors: Bernd Amon, Herbert Albert, Peter Reif, Yohann Perrot, M. Stéphane Londos, Werner Peter

Patent number: 6824744Abstract: The invention relates to a catalytic converter, especially for motor vehicles, and to a method for the production thereof. The inventive method is characterized in that a monolithic packet (17) consisting of at least one monolith (1) with wrap-around supporting matting (7) is pressed into a tube section (2) acting as a housing. The tube section (2) has two longitudinal sections (9, 10) with different inner cross-sectional surfaces. The monolithic packet (17) is pressed inwards from the end (21) of the tube section with the bigger or biggest inner cross-sectional surface. The inventive catalytic converter is characterized in that it has at least one contracted longitudinal section (9) with a reduced diameter (12) or reduced inner cross-sectional surface, whereby the inner surface (5a) of the tube section (2) runs parallel to the central longitudinal axis (32) thereof.Type: GrantFiled: June 5, 2000Date of Patent: November 30, 2004Assignee: Faurecia Abgastechnik GmbHInventors: Walter Stoepler, Thomas Buckel

Patent number: 6732511Abstract: The exhaust flap closes an exhaust duct. An exhaust-gas stream flows directly onto a closure plate which closes the cross section of the exhaust duct at least partially. A flow body is disposed next to the closure plate, onto which the exhaust-gas stream can flow and which takes effect as an actuator for the exhaust flap.Type: GrantFiled: October 19, 2001Date of Patent: May 11, 2004Assignee: Faurecia Abgastechnik GmbHInventors: Martin Unbehaun, Frank Jürgen Lehringer, Gerhard Zintel, Gerhard Olejniczak

Patent number: 6604759Abstract: A pipe connection of two pipe ends pushed into a sleeve. The pipe connection includes a spherical shape between the inside wall of the sleeve and the outside wall of at least one pipe end.Type: GrantFiled: September 24, 2001Date of Patent: August 12, 2003Assignee: Faurecia Abgastechnik GmbHInventor: Harald Binöder

Patent number: 6527820Abstract: A soot filter for the exhaust gas of a diesel engine comprises a filter body and a glow plug for thermally regenerating the filter body. At least one glow rod has a contact part that is spring-mounted at the glow rod in an axially displaceable fashion. Its face side which is averted from the glow plug shaft, therefore, protrudes beyond the free end of the glow rod and is pressed onto the face of the filter body.Type: GrantFiled: June 18, 2001Date of Patent: March 4, 2003Assignee: Faurecia Abgastechnik GmbHInventor: Walter Stöpler
