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.
