Summary:A method to determine the actual quantity of metal powders or ashes trapped in a particulate filter, which involves determining an estimated value of the quantity of metal powders trapped in the particulate filter based on an estimation model; determining a measured value of the quantity of metal powders trapped in the particulate filter; updating the estimated value of the quantity of metal powders trapped in the particulate filter as a function of the measured value; and determining the actual quantity of metal powders or ashes trapped in a particulate filter as a function of the update of the estimated value of the quantity of metal powders trapped in the particulate filter.
