摘要：A method for operating a particulate filter disposed in an exhaust-gas region ofan internal combustion engine and a device for implementing the method. Based on an oilsignal provided by an oil sensor, an oil-consumption determination determines the oilconsumption of the internal combustion engine. From the oil signal, an ash-load
determination calculates a measure for the ash-load state of the particulate filter, whichcan be taken into account for the operation of the particulate filter, particularly inestablishing a threshold value for the maximum permissible particulate-load state.Moreover, a filter replacement signal can be obtained from the ash-load state.
