An annular catalytic converter, having a first, tubular flow path, having a diverting region and having a second, annular flow path, wherein the tubular flow path is formed by an inner pipe, wherein the annular flow path is formed between the inner pipe and an outer pipe surrounding the inner pipe, and the diverting region 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 and/or the outer pipe has a conical cross section that widens or narrows along the flow direction of the exhaust gas.

Annular catalytic converter

A device for exhaust-gas aftertreatment, such as an annular catalytic converter, having a first, tubular flow path, having a diverting chamber and having a second, annular flow path, wherein the tubular flow path is delimited outwardly in the radial direction by an inner pipe and the second, annular flow path is delimited inwardly in the radial direction by the inner pipe and outwardly in the radial direction by an outer pipe, and the diverting chamber is designed to divert the exhaust-gas flow from the tubular flow path (8) into the annular flow path, wherein the annular catalytic converter has at least one annular substrate body which has a catalytically active coating applied to it and which is arranged in the annular flow path.
