Abstract
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.
