Claim Text:
1. A method for detecting the development of detonation phenomena in an internal combustion engine ( 1 ) provided with a number of cylinders ( 2 ), a control unit ( 16 ), and a number of detonation sensors connected to the control unit ( 16 ); wherein, detonation sensors include at least one of an accelerometer and a voltage gauge which is connected and arranged in series to the electric circuit of a spark plug ( 15 ) to measure the voltage at the terminals of the electrodes of the spark plug ( 15 ) during combustion and/or a pressure gauge which measures the maximum amplitude pressure oscillation (MAPO) of the intensity of the pressure waves generated in the cylinders ( 2 ) during combustion; the method comprises the steps of: acquiring the signal (S) coming from said number of detonation sensors connected to the control unit ( processing the signal (S) coming from said number of detonation sensors connected to the control unit ( filtering the detonation energy (μ calculating the mean detonation energy (μ comparing the detonation energy (μ determining the variance (σ calculating the maximum variance (σ comparing the maximum variance (σ determining the development of detonation phenomena for each combustion taken into account for a given cylinder (
