| description | A particulate trap regeneration system is provided, which may include a particulate trap having a filter medium configured to remove one or more types of particulate matter from an exhaust flow of an engine and a regeneration device configured to reduce an amount of particulate matter in the particulate trap, as well as a radio frequency-based particulate loading monitoring system configured to determine an amount of particulate matter trapped by the filter medium. The particulate loading monitoring system may include at least one radio frequency transmitting probe configured to transmit radio frequency signals of predetermined magnitude and predetermined frequency toward the filter medium and at least one radio frequency receiving probe configured to receive and measure the magnitude of received radio frequency signals that pass through the filter medium. Further, the system may include a temperature sensing device configured to take a temperature measurement indicative of a temperature of the particulate trap at the time the radio signals are received by the receiving probe and a controller, which may be configured to determine, based on the measured magnitude of received radio frequency signals, a particulate loading value indicative of the amount of particulate matter trapped in the filter medium. The controller may also be configured to perform a temperature compensation including modifying, based on the temperature measurement, at least one of the following: the measured magnitude of the received radio frequency signals that pass through the filter medium or the particulate loading value. |
