Abstract
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.

A mixing chamber for mixing an additive with exhaust gas in an exhaust system of an internal combustion engine, comprising:
- a housing including an entry opening for exhaust gas having a first flow cross-section and a central entry axis and an exit opening for exhaust gas having a second flow cross-section and having a central exit axis;
- a flow-guiding element arranged within the housing between the two openings, the flow-guiding element is tubular and forms a channel including a channel wall, one inlet and one outlet, via which the exhaust gas is guided through the channel to the outlet having an outlet cross-section including a size and a shape;
- and
- a downstream conduit positioned adjacent to the outlet in the direction of the central exit axis, the downstream conduit having a conduit cross-section including a size and a shape that corresponds to the outlet cross-section size and shape, wherein the housing includes a dome that radially protrudes to provide a path for the exhaust gas to enter the inlet, wherein the inlet is at least partially positioned in the dome.
A mixing chamber for mixing an additive with exhaust gas in an exhaust system of an internal combustion engine, comprising:
- a housing including an entry opening for exhaust gas having a first flow cross-section and a central entry axis and an exit opening for exhaust gas having a second flow cross-section and having a central exit axis;
- a flow-guiding element arranged within the housing between the two openings, wherein the flow-guiding element is tubular and forms a channel including a channel wall, an inlet and an outlet, via which all of the exhaust gas passing through the entry opening is guided through the channel to the outlet, wherein the outlet includes an outlet cross-section including a size and a shape, wherein the channel is adapted to receive the additive;
- and
- a downstream conduit positioned adjacent to the outlet in the direction of the central exit axis, the downstream conduit having an inlet opening with a cross-section including a size and a shape that corresponds to the outlet cross-section size and shape.
