Patent number: 11898484Abstract: A mixing subassembly for an exhaust gas system of an internal combustion engine for mixing exhaust gas, which is discharged by an internal combustion engine, with reactant includes a mixing path which extends in the direction of a mixing path longitudinal axis and which has an upstream mixing path inflow region for receiving exhaust gas and/or reactant in the mixing path. The mixing path includes a core flow channel, through which a first exhaust gas partial flow flows, and a bypass flow channel, through which a second exhaust gas partial flow flows. At least one flow blocking element reduces a flow cross section of the bypass flow channel and is arranged in the bypass flow channel.Type: GrantFiled: February 3, 2023Date of Patent: February 13, 2024Assignee: Purem GmbHInventors: Philipp Weinmann, Vincent Eder, Mathias Rothfuss, Tobias Wolf, Michael Dentler, Alexander Kauderer

Patent number: 11795860Abstract: An exhaust gas treatment assembly for an exhaust gas system of an internal combustion engine includes a housing defining a longitudinal axis. A first exhaust gas treatment unit is inserted in the housing and has a first casing and at least one first exhaust gas treatment unit carried in the first casing. A second exhaust gas treatment unit is inserted in the housing and has a second casing and at least one second exhaust gas treatment unit carried therein. A locking arrangement is for locking a first exhaust gas treatment unit in the housing at least against movement in the direction of the longitudinal axis in a locked state, wherein, when the first exhaust gas treatment unit and the second exhaust gas treatment unit are inserted in the housing, the locking arrangement is blocked in the locked state by the second exhaust gas treatment unit.Type: GrantFiled: February 4, 2022Date of Patent: October 24, 2023Assignee: Purem GmbHInventors: Shengxiao Lin, Kirill Karelin, Alexander Kauderer

Patent number: 10697338Abstract: An exhaust system for an internal combustion engine, especially diesel internal combustion engine, includes an exhaust gas flow duct (12). At least one exhaust gas treatment unit (23, 26, 28, 30) is provided in an exhaust gas treatment duct area (16) of the exhaust gas flow duct (12). The exhaust gas treatment duct area (16) of the exhaust gas flow duct (12) extends, in at least some areas, in an insulation volume (20), through which exhaust gas discharged from the exhaust gas treatment duct area (16) can flow.Type: GrantFiled: January 4, 2018Date of Patent: June 30, 2020Assignee: Eberspächer Exhaust Technology GmbH & Co. KGInventors: Felix Neumann, Alexander Kauderer, Wolfgang Datz, Philip Weinmann, Simon Krammer, Andreas Sauer

Patent number: 10294847Abstract: An exhaust gas treatment device (1), for an exhaust system of an internal combustion engine, is equipped with a housing (2). At least one mounting pipe (3), which contains a mounting space (4), is arranged within the housing. At least one cartridge (5) is arranged replaceably in the mounting space (4) and has a cartridge pipe (6) as well as at least one exhaust gas treatment element (7) arranged in the cartridge pipe (6). The cartridge pipe (6) is supported axially under axial prestress at an annular step (9) at least on an axial front side (31) via at least one spring element (27).Type: GrantFiled: August 3, 2016Date of Patent: May 21, 2019Assignee: Eberspächer Exhaust Technology GmbH & Co. KGInventors: Felix Neumann, Alexander Kauderer, Simon Krammer, Kirill Karelin

Patent number: 9810123Abstract: An exhaust system injection section (10) includes an exhaust gas flow channel (19), a laterally arranged injector connection (21), with a fluid introducing injector (22) and an injection chamber (24) formed in the channel, which is delimited by a perforated first separating wall (25), arranged in the channel upstream of the injector connection, and a perforated second separating wall (26) arranged in the channel downstream of the injector connection. To provides intensive mixing of the injected fluid with the exhaust gas flow a perforation (29) of the first separating wall (25) is configured so that exhaust gas largely flows eccentrically through the first separating wall (25) with respect to a longitudinal center axis (23) of the channel and a perforation (31) of the second separating wall (26) is configured so that exhaust gas largely flows concentrically through the second separating wall (26) with respect to the longitudinal center axis (23).Type: GrantFiled: November 5, 2015Date of Patent: November 7, 2017Assignee: Eberspächer Exhaust Technology GmbH & Co.
