Abstract (en)
[origin: EP0854274A1] The filter is regenerated by burning-off the collected particles. During this process, the exhaust pressure in front of the particle filter (3) is maintained at a level, which is required for complete burn-off of the particles. The load- independent flow resistance of a filter (1) across its complete flow profile, is at least 5% of the flow resistance of the regeneration threshold of the laden particle filter. The filter medium is formed by solid walls of porous, heat- resistant material, with a flow resistance, which is influenced by wall thickness, porosity, and degree of surface coating. The filter is preferably a honeycomb, and a drag body (4) is positioned in front of or behind it.
