Abstract

Embodiments for an exhaust gas aftertreatment device are provided. In one example, an exhaust gas aftertreatment device for a gasoline engine comprises a filter body with porous filter walls through which exhaust gas flows to remove soot, the porous filter walls containing a first catalyst material and having a coating of a second catalyst material on partial areas of the filter walls. In this way, a particulate filter and catalyst may be provided in a common aftertreatment device.
