摘要
A method of estimating the MFB50 combustion index of the cylinders (2) of an internal combustion engine (1) provided with a drive shaft (4) coupled to at least a pair of position sensors (5,5*; 5A, 5B), each of which is arranged at a respective end of the drive shaft (4); the estimation method comprising the steps of: acquiring the signals coming from two position sensors (5,5*; 5A, 5B); determining the angular torsion (”¸) of the drive shaft (4) based on the signals from the two position sensors (5,5*; 5A, 5B); and estimating the MFB50 combustion index of the single cylinders (2) of the internal combustion engine (1) based on the angular torsion (”¸) of the drive shaft (4).
