<p>The invention concerns an arrangement (100) tor filtering soot particles from an exhaust flow of a combustion engine (2). The arrangement comprises an exhaust collector ( 20), which collects exhaust from the cylinders ( 2a-2f) of the combustion engine, wherein each of the cylinders (2a-2f) is connected to the exhaust collector (20) via an outlet duct ( 22a-22f). A filter device ( 24; 24'; 24a-24f) is arranged in each of the outlet ducts (22a-22f) between the cylinders (2a-2f) of the combustion engine and the collecting chamber (21) of the exhaust collector (20), wherein each of the filter devices (24; 24'; 24a-24f) comprises a fiber filter (240; 240') of silicon dioxide fibers and is adapted so as to filter particles from the exhaust flow in that the particles adhere to or are captured by the fibers of the fiber filter. The invention also concerns a filter device (24; 24'; 24a-24f) for the arrangement (100) and an exhaust system that contains the arrangement and/or the filter device, and a vehicle that contains the exhaust system. Soiling of equipment downstream of a combustion engine in relation to the direction of exhaust flow can be reduced by means of the arrangement, and the total atmospheric emissions can also be reduced.</p> |
