Filter element for diesel particle filter of internal-combustion engine, has electrical heating device provided in flow direction in front of outer area of surface, where area lies radially outward

摘要

The element (18) has a withdrawal surface (24) including two groups of channels (28, 30) separated by filter walls made of an open-porous material. An electrical heating device is provided in a flow direction in front of an outer area of a surface (22), where the area lies radially outward. The electrical heating device extends across the entire area of the filter element. The electrical heating device has more than one electrical heating resistor. An independent claim is also included for a method for regenerating a filter element of a filter device of an internal-combustion engine.
