A device for purifying an exhaust gas contains at least one first and one second component with a respective shell and core through which the exhaust flows, as well as with two front faces each. At least one of the front faces of the first component and at least one front face of the second component has a predetermined profile with elevations and depressions. The elevations of the front face of the first component extend into the depressions of the front face of the second component and vice versa, thereby configuring a penetration section. The first component is disposed electrically insulated from the second component. The components have a potential difference between them and plasma is generated in the penetration section. The compact plasma reactor reduces the pollutant concentration in the exhaust gas of an internal combustion engine operated in the lean mode, especially when combined with an oxidation catalyst.
A device for purifying an exhaust gas from an internal combustion engine, the device comprising:
A method of operating a device for purifying an exhaust gas from an internal combustion engine, the device containing components including at least a first component and a second component, each of the components having a shell and a core through which the exhaust gas flows, the components each having two end faces and at least one of the end faces of the first component and at least one of the end faces of the second component having a predeterminable profile containing elevations and depressions, the elevations of the end face of the first component extending into the depressions in the end face of the second component and vice versa, thereby forming a penetration section, the first component disposed so that the first component being electrically insulated from the second component, the components having a potential difference with respect to one another and a plasma being generated in the penetration section, which comprises the steps of:
