摘要： A mixer for an exhaust system of an internal combustion engine for mixing additives into an exhaust gas flow, with at least one inlet pipe having a pipe axis, with at least one outlet pipe having a pipe axis and with a housing for receiving the inlet pipe and the outlet pipe, wherein the outlet pipe has an inner part which is arranged within the housing and is provided with at least one outflow opening for the purpose of conducting the exhaust gas out of the housing, wherein the housing has a first housing part with a first housing edge and at least one second housing part with a second housing edge, wherein the two housing parts are at least partially connected via the housing edge, and in that the inlet pipe has an inner part which is arranged within the housing and is provided with at least one inlet opening for the purpose of introducing the exhaust gas into the housing, wherein a) the respective housing edge as at least two formations, each having a center axis, and/or b) the respective housing part has at least two rim holes, each having a center axis, and the respective pipe has bearing points via which said pipe is mounted within the formations or within the rim holes, wherein i) the respective pipe is formed symmetrically with respect to the design of the bearing points, and, for the purpose of installation, can be mounted in at least two different positions R1, R2 in the respective formation, or ii) the inlet pipe and the outlet pipe are of identical design with respect to the design of the bearing points, or iii) the two housing parts are connectable in a plurality of positions S1, S2 relative to each other via the housing edge.

摘要： 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°. The mixing chamber is to be designed and arranged in such a way that, with a reduced overall length, an improved distribution of the mixture of exhaust gas and additive over the substrate surface is achieved and at the same time deposits of the additive are avoided. A downstream substrate is provided adjacent to the outlet in the direction of the central exit axis, the downstream substrate having a substrate cross-section that corresponds to the outlet cross-section.

摘要： 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.
