Abstract

In a regenerable soot filter for the exhaust gas of diesel engines, the thermally insulated housing (1) is divided into a box-shaped main part (2) and an end face cover (3'). The combustion chamber for burning the catalytically deposited soot particles has the form of a separate combustion chamber (11') which is separated from the housing (1) and is combined with the filter bodies (14) to form a unit which is held in a detachable manner in the housing (1). <IMAGE>
