  • Patent number: 12241396
    Abstract: An exhaust-gas treatment arrangement for an exhaust-gas system of a combustion engine has a first exhaust-gas treatment unit and, downstream thereof, an exhaust-gas treatment assembly. The treatment unit and the treatment assembly are arranged axially one after the other in the direction of a flow-path longitudinal axis of a flow path including the treatment unit and the treatment assembly. A hydrocarbon introducer for introducing hydrocarbon into exhaust gas flowing in the flow path is in the flow path substantially axially between the treatment unit and the treatment assembly. The hydrocarbon introducer includes an introduction ring flow channel annularly surrounding the flow-path longitudinal axis. The channel is open in an upstream end region toward an outlet region of the treatment unit and is open in a downstream end region toward an inlet region of the treatment assembly. The hydrocarbon introduction assembly includes a discharging unit for discharging hydrocarbon into the channel.

  • Publication number: 20240183305
    Abstract: An exhaust-gas treatment arrangement for an exhaust system of an internal-combustion engine includes a diesel internal-combustion engine. The arrangement includes a first exhaust-gas treatment unit and, downstream of the first exhaust-gas treatment unit, an exhaust-gas treatment assembly. The first exhaust-gas treatment unit and the exhaust-gas treatment assembly are arranged axially succeeding one another in the direction of a longitudinal axis of a flow path encompassing the first exhaust-gas treatment unit and the exhaust-gas treatment assembly. A hydrocarbon-feeding assembly is provided for feeding hydrocarbon into exhaust gas flowing in the flow path. The hydrocarbon-feeding assembly includes a hydrocarbon-dispensing unit dispensing hydrocarbon into the flow path downstream of the first exhaust-gas treatment unit and upstream of the exhaust-gas treatment assembly. A swirl-flow-generating unit is provided in the flow path upstream of the hydrocarbon-dispensing unit.

  • Publication number: 20240183297
    Abstract: An exhaust-gas treatment arrangement for an exhaust gas system of an internal combustion engine includes a first exhaust-gas treatment unit and an exhaust-gas treatment assembly being arranged axially one after the other in the direction of a longitudinal axis of a flow path. The flow path includes the first exhaust-gas treatment unit and the exhaust-gas treatment assembly. A hydrocarbon introduction assembly for introducing hydrocarbon into exhaust gas flowing through the exhaust-gas treatment arrangement is provided. The hydrocarbon introduction assembly includes a bypass flow channel which includes a flow-channel inlet region for receiving exhaust gas upstream of the first exhaust-gas treatment unit and a flow-channel outlet region for discharging exhaust gas or/and hydrocarbon into the flow path downstream of the first exhaust-gas treatment unit and upstream of the exhaust-gas treatment assembly.
