Patent number: 11492942Abstract: An exhaust gas heater for an exhaust gas system of a combustion engine includes a carrier and a heating conductor supported on the carrier. The heating conductor includes a heating region arranged on an axial side of the carrier, wherein the heating conductor is electrically uninsulated in its heating region at least in part. A holding arrangement has at least one holding unit which holds the heating conductor on the carrier in its heating region. The holding unit includes at least one electrically conducting holding block which is in contact with the heating conductor in an electrically uninsulated region of the heating region. The holding block is electrically insulated with respect to the carrier.Type: GrantFiled: April 22, 2021Date of Patent: November 8, 2022Assignee: Purem GmbHInventors: Enver Kurpejovic, Fatih Uysal, Holger Prommersberger, Dietmar Kuschel, Sandra Hoeckel

Patent number: 7861824Abstract: The invention relates to a sound absorber for an exhaust system having a Y-shaped feed piece arranged upstream from the sound absorber, combining two exhaust gas-carrying lines to form a single line entering into the sound absorber whereby the Y-shaped feed piece and the sound absorber are assembled from a common bottom shell and a common top shell. The invention also relates to an exhaust system equipped with the sound absorber.Type: GrantFiled: July 14, 2005Date of Patent: January 4, 2011Assignee: J. Eberspacher GmbH & Co. KGInventor: Holger Prommersberger

Patent number: 7384613Abstract: The present invention relates to a catalyst for an internal combustion engine, particularly of a motor vehicle, with a housing, which is assembled from at least two housing portions, telescopically inserted one into another in the throughflow direction of the housing, which is assembled from two housing portions telescopically inserted one into the other. A first monolith is mounted in a first housing portion, and a second monolith is mounted in a second housing portion. In an insertion region, an outer end section of the second housing portion and an inner end section of the first housing portion inserted into the outer end section mutually overlap. A transition zone, in which the monoliths, are spaced apart from one another in the throughflow direction, is formed within the insertion region.Type: GrantFiled: April 23, 2003Date of Patent: June 10, 2008Assignee: J. Eberspacher GmbH & Co. KGInventors: Holger Prommersberger, Jochen Hägele, Georg Wirth
