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.

Control method in the case of a fault in an internal combustion engine; the control method provides for the phases of: cyclically checking the correct functioning of a connection between an electronic control unit and an electric drive of an electric actuator coupled to a butterfly valve to control the position of the same butterfly valve, switching off the electric drive in the case of interruption in the connection between the electronic control unit and the electric drive so that the butterfly valve sets itself in a predefined limp-home position, and piloting the engine in the case of interruption in the connection between the electronic control unit and the electric drive to keep the number of revs constant and equal to a predefined emergency value.
