Abstract
A method of detecting during a combustion cycle a peak value of pressure in a cylinder of an internal combustion engine includes providing and installing on the engine body an accelerometer that generates an acceleration signal representing vibrations of the engine body. The acceleration signal is filtered by comparing the band-pass filtered replica of the acceleration signal to a threshold. When the threshold is surpassed, a pressure peak is detected and flagged.
