摘要： A method of detecting ash in an exhaust particulate filter system (22) for an internal combustion engine (18) includes transmitting electromagnetic energy through an exhaust particulate filter (24) containing soot and ash, and sensing a strength of the transmitted electromagnetic energy after having been attenuated in response to the soot. The method further includes electronically storing a filter monitoring history responsive to a difference between the transmitted strength and the sensed strength of the electromagnetic energy, and detecting an amount of the ash based at least in part upon a pattern of electromagnetic energy attenuation defined by the stored filter monitoring history. An exhaust particulate filter system (22) for implementing related methodology includes a microprocessor (46) configured to determine a value indicative of an amount of ash contained within an exhaust particulate filter (24) responsive to a pattern of electromagnetic energy attenuation defined by a stored filter monitoring history.

摘要： A method of operating an exhaust particulate filter system (20) for an internal combustion engine (18) includes transmitting electromagnetic energy, for example having a frequency above about 2 GHz through an exhaust particulate filter (22) containing trapped soot. The transmitted electromagnetic energy may be attenuated in response to the trapped soot, and a filter soot loading value calculated based at least in part upon a correlation among an attenuation of the electromagnetic energy, a temperature of the filter, and a mass of the trapped soot. An algorithm based upon a partial derivative of an equation representing the correlation may be used in calculating the filter soot loading value, and a resulting soot mass. Responsive to determining the calculated soot mass satisfies regeneration suitability conditions, a regeneration initiation command may be outputted.
