Abstract:
1. A method for the operation of a particulate filter system for an internal combustion engine, an exhaust gas stream entering a housing, the housing receiving a particulate filter via a gas inlet opening, the exhaust gas stream flowing into a crude gas duct connected to the gas inlet opening, and flowing out of the particulate filter via clean gas ducts separated from the crude gas ducts, the clean gas ducts being in fluid connection with a gas outlet opening, the crude gas ducts being connected to a connection space in the direction of flow, and the connection space has an exhaust port controlled by a closing mechanism, the method comprising: discharging a partial exhaust gas stream of the exhaust gas stream into the environment via the exhaust port according to a particulate load, as the primary exhaust gas stream is discharged via the gas outlet opening into the environment; and closing the exhaust port when conditions are favorable for regeneration of the particulate filter with a soot oxidizing agent.
