Abstract
A method for detecting the development of detonation phenomena in an internal combustion engine () which includes determining the variance (σ) of each combustion taken into account for a given cylinder () and in a given engine point as a function of the comparison between the detonation energy (μ) of each combustion taken into account and the self-learnt mean detonation energy (μ) for the given cylinder () and in the given engine point; calculating the maximum variance (σ) for a given cylinder () and in a given engine point with a reduction of the spark advance actuated in the given cylinder (); and determining the development of detonation phenomena for each combustion taken into account as a function of the comparison between the maximum variance (σ) and the variance (σ) of each combustion taken into account for a given cylinder () and in a given engine point.
