    Abstract: A method of estimating a total amount of soot in a diesel particulate filter includes monitoring a pressure differential across the diesel particulate filter; monitoring an engine speed and an engine load from an engine in fluid communication with the diesel particulate filter; determining a first soot mass estimate from the monitored pressure differential, the first soot mass estimate having an associated confidence indicator based on the monitored engine speed and engine load; determining a second soot mass estimate from the monitored engine speed and engine load; and outputting the first soot mass estimate if the confidence indicator is above a predetermined threshold, and outputting the second soot mass estimate if the confidence indicator is below the predetermined threshold.

    Abstract: An exhaust gas treatment system for an internal combustion engine to control desulfurization of at least one aftertreatment device is provided. The exhaust gas treatment system includes a desulfurization mode trigger module, a desulfurization control module, and an interrupt module. The desulfurization mode trigger module is configured to set a desulfurization request based on one or more trigger conditions. The desulfurization control module is configured to control desulfurization of at least one aftertreatment device based on the desulfurization request. The interrupt module is configured to interrupt the desulfurization of at least one aftertreatment device based on an interrupt condition.
