Abstract

A process for detecting a misfire in one or more cylinders (3, 3') of an internal combustion engine, including the following operative steps: sampling the exhaust gas pressure values during at least one engine cycle, the sampling frequency being proportional to the crankshaft rotational speed; analyzing the sampled signal in the frequency domain; calculating a misfire index as a function of the results of said analysis;
comparing said index with one or more threshold values. Said frequency domain analysis preferably includes a Fourier transform of the sampled signal. The present invention also relates to a system carrying out said process.
