Abstract
A diesel particle filter for lowering the emission of particles contained in the exhaust gas of a Diesel engine, is disclosed with the impaction surface of the diesel particle filter is developed such that binding forces of the ash to filter is lowered. Therefore, the adhesion of noncombustible ash particles occurs, if at all, on the impaction surface of the diesel particle filter at only with such binding forces that more the ash particles can be removed from this surface of the diesel particle filter with a fluid and/or by vibrational effects.
