Abstract (en)
[origin: EP1188907A2] Before passing through the filter the exhaust gas is heated up by heating means (3) and at least one partial stream of exhaust gas inside the exhaust pipe (1) is additionally heated so that the partial stream enters the filter at a higher temperature than the other exhaust gas stream. Independent claim describes regenerating device with heating means (3) in exhaust pipe which divides gas stream into at least two partial streams so that one is additionally heated to higher temperature. The heating means can be made from conductive ceramic. It can be a heating strip (4) set in the region of the exhaust pipe to form split channels.
