Abstract
Die Erfindung betrifft einen Rußfilter für Dieselfahrzeuge mit einem in einem Gehäuse (25) gelagerten Filterkörper (1) insbesondere aus Keramik und wenigstens einem auf der Einlassseite des Filterkörpers (1) angeordneten und am Gehäuse fixierten Heizelement. Im Filterkörper (1) ist wenigstens eine sich in die vom Abgasstrom beaufschlagte vordere Stirnseite (7) des Filterkörpers (1) öffnende Ausnehmung (12) vorhanden, in die sich das Heizelement mit Axial- und Radialabstand hineinerstreckt. The invention relates to a soot filter for diesel vehicles with a filter body (1) mounted in a housing (25), in particular made of ceramic, and at least one heating element arranged on the inlet side of the filter body (1) and fixed to the housing. In the filter body (1) there is at least one recess (12) which opens into the front end face (7) of the filter body (1) and into which the heating element extends at an axial and radial distance.
