摘要： A method for the operation of a particulate filter system for an internal combustion engine wherein an. An exhaust gas stream enters a housing via a gas inlet opening. The housing receives a particulate filter, the stream flows into crude gas ducts connected to the gas inlet opening, and the stream can flow out of the particulate filter via clean gas ducts that are in fluid connection with a gas outlet opening, and are separated from the crude gas ducts. The crude gas ducts are connected to a connecting space in the direction of flow, and the connecting space has an exhaust port controlled by a closing mechanism. According to the invention, a method for operating an open particulate filter system is provided, by which the degree of separation of the soot particles from the exhaust gas can be increased. This is achieved in that a partial exhaust gas stream of the exhaust gas stream can be discharged via the exhaust port into the environment, just as the primary exhaust gas flow can be discharged into the environment via the gas outlet opening, according at least to a particulate load thereof.

摘要： A method for operating a filter includes forcibly passing a stream of a fluid through a filter wall of the filter from a raw gas side to a clean gas side of the filter so as to separate out particles and particle constituents from the stream, wherein the particles and particle constituents are collected on the raw gas side and performing a regeneration process on the filter during operation of the filter. The regeneration process includes removing particles and particle constituents from the raw gas side of the filter and moving the removed particle constituents to a receiving device disposed on the raw gas side. Alternatively, the filter walls includes a plurality of channels on the raw gas side, each channel closed by a closure wall configured to be partially opened to enable the disposing of the particle constituents.
