  • Patent number: 12201941
    Abstract: 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.
    Type: Grant

  • Patent number: 12168203
    Abstract: 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.

  • Publication number: 20240375094
    Abstract: A method for producing a device for the aftertreatment of exhaust gases and for coating a honeycomb body, provided in the device, with a catalytically active surface coating. The honeycomb body is formed from a multiplicity of metallic, at least partially structured foils stacked one on another and wound so that the honeycomb body forms a multiplicity of flow channels through which fluid can flow along a main flow direction. The honeycomb body is received in an inner casing and is durably connected thereto. The inner casing is arranged in an outer casing serving as a housing and is durably connected thereto. Before the introduction of the catalytically active coating into the flow channels formed by the honeycomb body, an air gap or air gaps, which have been formed between the outer casing and the components arranged therein, are filled by a filler.

  • Publication number: 20220106899
    Abstract: 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.

  • Publication number: 20220072474
    Abstract: 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.
