Abstract: 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.

Abstract: It is described a method to control the amount of particulate coming out of a particulate filter for an internal combustion engine comprising: estimating an objective value of the amount of particulate coming out of the particulate filter; determining an amount of particulate trapped in the particular filter, which allows reaching said objective value of the amount of particulate coming out of the particulate filter; and adjusting an amount of particulate produced by the internal combustion engine and/or an amount of particulate burnt in the particulate filter based on said amount of trapped particulate.
