摘要： A particulate trap regeneration system (16) is provided. The system may include a particulate trap (19) having a filter medium (24) configured to remove one or more types of particulate matter from an exhaust flow of an engine (14). The system includes a radio frequency-based particulate loading monitoring system (44) configured to determine an amount of particulate matter trapped by the filter medium. The determination may be accomplished by transmitting radio frequency signals having frequencies less than 500 MHz and measuring the magnitude of the received radio signals that pass through the filter medium. In addition, the system includes a controller (28) configured to activate a regeneration device. The controller is configured to perform a temperature compensation including modifying, based on temperature measurement, at least the measured magnitude of the received radio frequency signal or the particulate loading value.

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 (22), 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. The calculated soot mass is used to determine a relative soot loading state of the filter (22) in conjunction with information as to ash loading. Responsive to determining the relative soot loading state satisfies regeneration suitability conditions, a regeneration initiation command may be outputted.
