Abstract
The method includes the steps of generating a detonation signal related to the intensity of the vibration on an engine block; wide-band filtering the detonation signal; rectifying the filtered detonation signal; integrating the rectified signal; calculating the logarithm of the integration result; calculating a mean value as a function of the calculated logarithm; calculating the values of a first and second standard-deviation-related quantity as a function of the logarithm value and the mean value; and calculating a detonation coefficient value as a function of the values of the standard-deviation-related quantities.
