Patent number: 11187133Abstract: A mixing chamber for mixing an additive in an exhaust system of an internal combustion engine includes a housing, a flow-guiding element and a downstream substrate. The flow-guiding element is arranged within the housing between an inlet opening and an outlet opening. The flow-guiding element is tubular and forms a channel including a channel wall, one inlet and one outlet, via which all of the exhaust gas is guided through the channel to the outlet.Type: GrantFiled: September 28, 2018Date of Patent: November 30, 2021Assignee: Tenneco GmbHInventors: Joachim Gehrlein, Frank Terres, Andreas Lang

Patent number: 10208645Abstract: A mixing chamber for mixing an additive in an exhaust system of an internal combustion engine, having a single-part or multi-part housing which has an entry opening for exhaust gas having a flow cross-section and having a central entry axis, and which has, arranged downstream of the entry opening, an exit opening for exhaust gas having a flow cross-section and having a central exit axis. A flow-guiding element is arranged within the housing between the two openings, wherein the flow-guiding element is tubular and forms at least one channel having a channel axis, said channel having an inlet and having an outlet, via which the entire exhaust gas stream is guided, in a flow direction parallel to the channel axis, to the outlet having an outlet cross-section, and the flow direction deviates relative to the central exit axis by an angle a of between 20° and 80°.Type: GrantFiled: August 5, 2014Date of Patent: February 19, 2019Assignee: TENNECO GMBHInventors: Joachim Gehrlein, Frank Terres, Andreas Lang

Method for inserting a ceramic functional body in a tubular metal housing and a device thus produced
Publication number: 20070048198Abstract: A method for inserting a ceramic functional body in a tubular metal housing is disclosed. After the functional body is measured, it is wrapped with a support mat and slid into the housing. This is followed by a heating step of the entire housing. In this state, the housing is then reduced to a dimension that results from the current dimension of the ceramic functional body plus the desired gap dimension in the hot state. Upon cooling, the housing shrinks, and the functional body and the support mat sit correctly in the housing.Type: ApplicationFiled: August 31, 2006Publication date: March 1, 2007Inventor: Frank Terres
