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.
Claims5
A particle filter of use in a diesel engine for lowering the emission of particles contained in the exhaust gas of the diesel engine, said particle filter comprising:
- an impaction side surface and an exhaust side surface;
- a separating medium removably applied to the impaction-side surface;
- the separating medium functioning to lower the adhesion of ash particles to at least one of each other and the impaction-side surface of the particle filter;
- and
- said separating medium being removable from the particle filter by effect of a fluid.
