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.
Claims1
A mixing chamber for mixing an additive 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 all of the exhaust gas is guided through the channel to the outlet having an outlet cross-section;
- and
- a downstream substrate positioned 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.
