  • Trapped soot measurement
    Patent number: 9422853
    Abstract: A quantity of soot trapped in a particulate filter in an engine exhaust system is calculated for use in a regeneration control strategy by drawing electric current from an electric power supply through a circuit which comprises in series an internal portion of the particulate filter and an electric impedance external to the filter. At least one electric measurement device connected to the circuit provides circuit-related data sufficient to enable a processor to calculate temperature-adjusted electric resistance of soot trapped in the internal portion of the particulate filter by calculating non-temperature-adjusted electric resistance of soot trapped in the internal portion of the particulate filter and temperature-adjusting a calculation of non-temperature-adjusted electric resistance of soot trapped in the internal portion of the particulate filter based on temperature data from a source of temperature data indicative of an internal temperature of the particulate filter.
