Abstract

The particle filter for cleaning the i.e. engine exhaust gas consists of a housing (1) with an inlet (5) and an outlet chamber (11), and an outlet pipe (12). The filter has a number of filter elements, which are supported at each end in retaining plates (2,3). The housing has an inlet for the exhaust gas and an additional inlet (8) for hot gases from an independent burner. The hot gases are used for burning off the carbon particles collected by the filter elements and to clean the filter. The inlet end support plate is provided with holes for the through flow of the exhaust gas and hot gases from the burner.
