Abstract
A device for aftertreatment of exhaust gases, having a flow section which is able to be flowed through by exhaust gas and has at least one honeycomb body, acting as a catalytic converter, and has at least one heating element. The heating element is formed from a ceramic material which is able to be flowed through along a plurality of flow channels from an inflow side to an outflow side. The heating element is electrically conductive along the walls delimiting the flow channels and, by an electrical contact, is connectable to a voltage source, wherein the heating element runs in a meandering manner over a through-flowable cross section of the flow section.
Claims7
A device for aftertreatment of exhaust gas, comprising:
- a flow section which is able to be flowed through by the exhaust gas;
- at least one honeycomb body configured as a catalytic converter;
- and
- at least one heating element formed from a ceramic honeycomb body which is able to be flowed through along a plurality of flow channels from an inflow side to an outflow side, wherein the at least one heating element runs in a meandering manner over a through-flowable cross section of the flow section,
- wherein the meandering manner comprises at least one deflection in a plane,
- wherein, at the deflection, the ceramic honeycomb body has a cell density that is higher in comparison with a remainder of the heating element,
- wherein the at least one heating element is electrically conductive along walls delimiting the flow channels;
- and
- an electrical contact configured for connection to a voltage source.
