Abstract: A method is described to control an actuation profile of an electromechanical linear actuator device of an internal combustion engine designed to control the movement of a component; the internal combustion engine comprises a sensor, which faces the actuator device and is designed to detect the noise generated by the movement of the component; the method comprises the steps of acquiring, by means of the sensor, the intensity of a signal generated by the impact of the component against a limit stop; identifying a first listening window of the signal associated with said impact; calculating a noise index inside the listening window; comparing the noise index with a reference value; and controlling the actuation profile of the actuator device based on this comparison.

Abstract: An actuator comprising a main body which delimits a kinematic chamber inside which a valve and/or a relative drive mechanism of the valve is at least partially housed, a closing lid that can be associated to close the kinematic chamber of the main body, wherein the throttle body contains a position sensor, of the magnetic or magneto-resistive type, facing a slider of the valve and/or a component of the drive mechanism so as to read the position of the slider and therefore of the relative valve and/or of the relative component of the drive mechanism. Advantageously, the closing lid is provided with a screening device of electromagnetic fields for the position sensor and the slider, positioned near the position sensor, on the side opposite the kinematic chamber with respect to the position sensor.

Abstract: Method to determine a closing instant of an electromagnetic fuel injector; in a beginning instant of the injection, a positive voltage is applied to a coil of an electromagnetic actuator so as to cause an electric current to circulate through the coil, said electric current determining the opening of an injection valve; in an end instant of the injection, a negative voltage is applied to the coil of the electromagnetic actuator so as to cancel the electric current circulating through the coil; a first voltage time development is detected at least one end of the coil of the electromagnetic actuator after the cancellation of the electric current circulating through the coil; the voltage actuation time development is compared with a voltage comparison time development; and the closing instant of the electromagnetic injector is determined based on the comparison between the voltage actuation time development and the voltage comparison time development.

Abstract: A rotor for a rotary electric machine; the rotor has: a shaft, which is mounted so as to rotate around a rotation axis; a magnetic core, which is arranged around the shaft and consists of a plurality of lamination sheets stacked together; and a pair of end discs, which are arranged around the shaft at the two opposite ends of the magnetic core and are designed to keep the lamination sheets of the magnetic core stacked together; wherein the end discs are designed to have balancing holes, which dynamically balance the rotor around the rotation axis. Each end disc consists of an inner component with an annular shape, which is arranged around the shaft and is made of a first metal material, and of an outer component with an annular shape, which is arranged around the inner component and is made of a second metal material, which is different from the first metal material and is non-magnetic.

Abstract: An instrument cluster is provided with a display panel having a plurality of graphic areas and with a backlighting device arranged behind the display panel for backlighting the graphic areas. The backlighting device has at least one light source and at least one light-guide element, which is provided with a receiving portion facing the light source for directly receiving a light beam and with at least one transmitting portion for transmitting and guiding the light towards at least one of the graphic areas. A cover is provided for shielding rays of light passing through the receiving portion and directed onto the display panel. The cover defines a channel, which has an inlet facing the receiving portion and at least one outlet facing one of the graphic areas. The channel is shaped in such a way as to transmit light indirectly from its inlet to its outlet.
