The invention relates to a device and a method for aftertreatment of exhaust gases from combustion engines, especially internal combustion engines. According to the invention, the device and method should be able to be constructed simply and be run cheaply, without exhaust gas flow characteristics being influenced in a detrimental manner. In order to solve this task, at least one area (3) containing metal balls, preferably hollow metal balls, is incorporated into an engine's exhaust flow stream. The combustion engine's exhaust gases are conducted through said area, thus enabling a simultaneous particle agglomeration and particle separation to take place. In addition to said area, the exhaust gases can be conducted through additional areas (5) filled with metal fibres that can be connected to at least one of the previous areas (3) filled with metal balls. |
