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.

Abstract: 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.

Abstract: Control method for a vehicle with an engine in the case of a fault that advises/imposes driving the vehicle with reduced performance; the control method provides for the phases of: diagnosing the fault, limiting the maximum performance of the vehicle by degrading the performance of an engine of the vehicle and giving the driver of the vehicle advance warning of the imminent operation of performance degradation on the engine before effectively degrading the performance of the engine.
