Abstract: A method and apparatus for maintaining a diesel particulate filter (DPF) is provided. A pressure drop across the DPF is measured and an initial estimate of soot loading in the DPF is provided to a recursive filter. Using the recursive filter, the initial estimate of soot loading is updated in view of the measured pressure drop to provide an updated estimate of soot loading in the DPF. Active regeneration of the DPF is triggered when an earliest one of at least one triggering condition occurs, the updated estimate of soot loading reaching a predetermined value being one of the at least one triggering condition.

Abstract: A method for controlling injection of a substance in a diesel engine exhaust aftertreatment system includes generating a feedforward signal as a function of a desired output signal, the desired output signal corresponding to an output sought to be achieved through injection of the substance. Actual system output is measured and an actual output signal is generated corresponding to an output actually achieved through injection of the substance. The desired output signal and the actual output signal are compared and an error signal is generated corresponding to a difference between the desired output signal and the actual output signal. A control signal is generated as a function of the error signal and the feedforward signal for controlling an amount of the substance to inject, and the feedforward signal is adjusted by an adaptive factor, the adaptive factor being a function of the error signal. A diesel engine is also provided.
