摘要： A method for reducing the particulate emissions containing carbon of diesel motors uses surface discharges to regenerate a filter. An appropriate wall flow filter is configured from alternately closed longitudinal channels. The electrodes are embedded in the filter material and are thus protected from erosion. Two electrodes are sufficient for selectively generating the surface discharges in the inlet channel of the wall flow filter as a result of a suitable geometric arrangement.

摘要： According to the invention, the emission of polycyclic aromatic hydrocarbons (PAH) from the exhaust-gas system of diesel motors with particle filters can be minimized or prevented. During the regeneration of the particle filter, the polycyclic aromatic hydrocarbons (PAH) are first fixed in adsorption layers and are cracked there at high temperatures. The cracking products are then preferably eliminated in an oxidation step.

摘要： This invention relates to an exhaust gas purifying apparatus having a particulate filter for collecting particulates in exhaust gas. This particulate filter (22) contains partition walls defining paths (50, 51) in which exhaust gas flows. This partition wall is formed of porous material. This particulate filter (22) is created by gathering tips of the partition walls and then baking with the adjacent partition walls being in contact with each other. The adjacent partition walls are bonded together at a predetermined bonding strength if the partition walls are baked such that they are in contact. According to this invention, the end portion of the particulate filter (22) has a higher strength than the predetermined bonding strength.
