Abstract (en)
[origin: EP2143921A1] Intended is to smoothen the dispersion of combustions between a plurality of cylinders satisfactorily. In an internal combustion engine having a plurality of cylinders, a fuel control system for smoothing the dispersion of the combustions between the cylinders detects an output signal (dÉact) indicating the running states of the internal combustion engine, sets a reference signal (Fcr#i) for each of the cylinders, takes a correlation between an output signal and the corresponding reference signal for each of the cylinders, and calculates the value of a correlation function (Cr#i). The fuel control system calculates a target value (Cr_trg) for the cylinders, and calculates a correction value (Kcom#i) for correcting a fuel injection rate (Kin#i) to the cylinders so that the value of the correlation function may converge to the target value for each cylinder. Here, one of the cylinders is set as a reference cylinder, and the reference signals set for the individual cylinders are generated on the basis of the signals obtained by extracting the portion corresponding to the reference cylinder, from the output signals.
