Abstract: Method to detect and control detonation phenomena in an internal combustion engine provided with a number of cylinders and with at least two detonation sensors. For each combustion cycle as a function of the cylinder and of the engine point that is being explored, the method comprises the steps of processing the signal coming from each detonation sensor so as to determine a detonation energy for each detonation sensor; calculating a detonation index for each detonation sensor and controlling the internal combustion engine as a function of a total detonation index through the algebraic sum of the detonation indexes for each detonation sensor.
