摘要： A hollow body for capturing particles includes at least one at least partially permeable wall extending between two at least partially oppositely disposed openings and along a first longitudinal direction. The hollow body has a primary cross-sectional shape defining a first cross-sectional area. At least one of the openings defines a second cross-sectional area. The second cross-sectional area is greater than the first cross-sectional area. An exhaust-gas treatment device having an exhaust line and a motor vehicle having an exhaust-gas treatment device are also provided.

摘要： A honeycomb body for an exhaust-gas purification system may be used, for example, as a carrier body for catalytically acting coatings or as a filter, absorber or mixer in the exhaust system of an internal combustion engine. The honeycomb body has channels, an axial main direction, a planar front surface, a planar end surface and a circumferential surface disposed parallel to the axial main direction. The front surface and/or the end surface are disposed obliquely with respect to the axial main direction. Such a honeycomb body is advantageous, in particular, for applying reducing agent to the oblique end or front surface. A method for producing a honeycomb body, an exhaust line section and a motor vehicle are also provided.

摘要： A device for cleaning exhaust gas from an internal combustion engine, especially a diesel engine, includes at least one catalyst carrier body through which an exhaust gas can flow. The catalyst carrier body is disposed in a casing tube and has a honeycomb-shaped structure. An electrical heating element has a supply terminal at each end and a twisted current path over an electrically insulating gap in the heating element. The heating element is a honeycomb body which is fixed to the catalyst carrier body by electrically insulating support elements and which is located downstream of the catalyst carrier body in exhaust gas flow direction. A honeycomb body, especially a particle filter, situated downstream, may be heated particularly effectively and a temperature required there may be reached and/or maintained, especially for igniting soot that has collected.
