Abstract: A method of estimating the MFB50 combustion index of the cylinders of an internal combustion engine provided with a drive shaft coupled to at least a pair of position sensors, each of which is arranged at a respective end of the drive shaft; the estimation method comprising the steps of: acquiring the signals coming from two position sensors; determining the angular torsion of the drive shaft based on the signals from the two position sensors; and estimating the MFB50 combustion index of the single cylinders of the internal combustion engine based on the angular torsion of the drive shaft.

Abstract: A method to control a supercharged internal combustion engine by means of a turbocharger provided with a turbine and a compressor which compresses the air taken in; the control method includes the steps of determining the instantaneous rotation speed of the turbocharger; and calculating the average power delivered by the turbine as a function of the absolute value of the j-th harmonic component of the instantaneous rotation speed of the turbocharger and of the instantaneous rotation speed of the turbocharger; and controlling the supercharged internal combustion engine as a function of the average power delivered by the turbine.
