Abstract: A method for recognising the type of fuel actually used in an internal combustion engine; the recognition method includes the steps of: sensing the intensity of the vibrations generated by the internal combustion engine within a measurement time window; determining the value of at least one synthetic index by processing the intensity of the vibrations generated by the internal combustion engine within the measurement time window; comparing the synthetic index with at least one predetermined comparison quantity; and recognising the type of fuel actually used as a function of the comparison of the synthetic index to the comparison quantity; and forcedly altering, when detecting the intensity of the vibrations, the engine control with respect to the normal standard engine control, so as to enhance the behavioural differences of the different types of fuel that can be used by the internal combustion engine.

Abstract: A method for detecting the development of detonation phenomena in an internal combustion engine (1) which includes determining the variance (σi) of each combustion taken into account for a given cylinder (2) and in a given engine point as a function of the comparison between the detonation energy (μi) of each combustion taken into account and the self-learnt mean detonation energy (μi_m) for the given cylinder (2) and in the given engine point; calculating the maximum variance (σi_max) for a given cylinder (2) and in a given engine point with a reduction of the spark advance actuated in the given cylinder (2); and determining the development of detonation phenomena for each combustion taken into account as a function of the comparison between the maximum variance (σi_max) and the variance (σi) of each combustion taken into account for a given cylinder (2) and in a given engine point.
