Abstract: An electronic monitoring circuit for detecting a variation in the power or current absorbed by an electronic circuit under test is disclosed. The circuit includes an input terminal adapted to receive a pulse-width modulation control signal, a resistor having a first terminal connected to the input terminal, and a capacitor having a first terminal connected to a second terminal of the resistor. The output terminal is adapted to generate an output signal as a function of the value of the voltage drop at the ends of the capacitor, said output signal being representative of a variation of the pulse width of the pulse-width modulation control signal. The variation of the pulse width is a function of the power or current absorbed by the electronic circuit under test.

Abstract: A method for monitoring an engine cylinder in an internal combustion engine includes, for each engine cycle, detection of the ionisation current generated in the cylinder in a predetermined time interval of a combustion cycle, generation of a signal representing the ionisation current and comparing a maximum value of the signal with a threshold value. Successively, the value of one or more parameters associated with the signal can be changed with respect to an equal number of corresponding reference values when the maximum value of the signal exceeds the threshold value, to reduce the maximum value of the signal in the time interval of a successive combustion cycle. The presence of water in the cylinder can be determined when the maximum value of the signal exceeds the threshold value for a predetermined first number of combustion cycles occurring within a predetermined period of time.

Abstract: An electric or hybrid electric-endothermic traction system, comprises an electric machine, an inverter, a battery, and a switching device configured to switch between a low-speed configuration, wherein the stator windings assume a first electric configuration, and a high-speed configuration, wherein the stator windings assume a second electric configuration, wherein the first electric configuration determines a voltage induced by the rotation of the rotor that, on reaching a pre-determined threshold value of the angular velocity of the rotor, exceeds a supply voltage of the battery pack, while the second electric configuration of the stator windings determines a voltage induced by the rotation of the rotor that is lower than the voltage of the battery for any angular velocity within a field of use of the machine. The switching device switches from the low-speed to the high-speed configuration when the rotor reaches a switching speed lower than or equal to the threshold value.

Abstract: A method of detecting the breakdown voltage between the electrodes of a spark plug connected to an ignition coil for a cylinder ignition system, in an internal combustion engine, includes a detection of an opening of the switch on the primary winding and a detection of a voltage on that primary winding, with the generation of a first signal representative of the voltage trend following the opening of the switch.
The first signal is then integrated and, following an identification of a breakdown at the ends of the spark plug, a breakdown voltage value is determined as a function of the value of the integrated signal at the time of the breakdown.
