Particulate filter e.g. soot filter used in exhaust gas in an internal combustion engine has filter medium and catalyst forming rope-like shape and wound into one of the cylindrical filters

摘要

In particulate filter, the filter medium (17) and catalyst (14) are formed into rope-like shape and are wound up into one of the cylindrical filters (13a, 13b,22), where the catalyst in front of the filter medium is arranged in the stream direction of fluid to be filtered. The particulate filter, particularly soot filter for exhaust gas on internal combustion engine, has a filter medium (17) and a catalyst (14), which has a housing with an outlet (11) and an inlet (12). An Independent claim is included for a filter (13a,13b,22).
