Abstract

See full text

A method of determining fuel quality in an internal combustion engine comprises the steps of: a) sampling a signal representative of the revolution speed of said engine during a sampling window, thereby obtaining an array of samples; and b) computing a Fourier component corresponding to a predetermined index in the frequency domain and determining a fuel quality indicator therefrom. The fuel quality indicator is representative of a magnitude of the Fourier component of this predetermined index.
