摘要： An exhaust-gas system for guiding and aftertreating exhaust gases from an exhaust-gas source, such as an internal combustion engine, with a flow section through which the exhaust gas may flow, with at least one component which is provided for the exhaust-gas aftertreatment, is arranged in the flow section and through which the exhaust gas may flow, and with an actuator for influencing the exhaust-gas flow in the flow section. The actuator is in fluid communication with the gas volume in the flow section, as a result of which the flow direction of the exhaust gas which flows through the flow section is influenced.

摘要： A device for exhaust-gas aftertreatment, having a first, tubular flow path, having a diverting region and having a second, annular flow path. The tubular flow path is formed by an inner pipe and the annular flow path is, by an outer pipe running substantially parallel to the inner pipe, formed between the inner pipe and the outer pipe, and the diverting region is designed to divert the exhaust-gas flow from the tubular flow path into the annular flow path. The device has an annular catalytically active substrate body and an annular particle filter, wherein the substrate body and the particle filter are arranged in the annular flow path.

摘要： The invention relates to an annular catalytic converter, having a first, tubular flow path, having a diverting region (4) and having a second, annular flow path, wherein the tubular flow path is formed by an inner pipe (1), wherein the annular flow path is formed between the inner pipe (1) and an outer pipe (2) surrounding the inner pipe, and the diverting region (4) is of pot-shaped form for the purposes of diverting the exhaust-gas flow from the tubular flow path into the annular flow path, wherein the inner pipe (1) and/or the outer pipe (2) has a conical cross section (D1, D2, D1, D4) that widens or narrows along the flow direction of the exhaust gas.

摘要： A honeycomb body for exhaust gas aftertreatment includes a plurality of interconnected metal foils stacked on one another. The honeycomb body has a central first flow channel running in the axial direction of the honeycomb body, as an inflow section, and has a plurality of second flow channels between in each case two mutually adjacent metal foils. The first flow channel is in fluid communication with the second flow channels. The second flow channels formed between two mutually adjacent metal foils run in a straight line and parallel to one another along a radial direction of the honeycomb body.
