Abstract (en)
[origin: EP0625635A1] An electronic system comprising first computing means (42, 140) supplied with a number of information signals (X1,...XN,Qt) measured in the engine and generating an injection time (T) computed on the basis of a characteristic (T=F(X1,...XN,Qt)) depending on the aforementioned signals; means (50, 56, 150, 180) for processing an expansion of the characteristic, which expansion is computed, as a function of a previously computed injection time and of a first value (Qt) of the significant information signal used for computing the injection time, about the first value (Qt) of the significant signal; and second computing means (56, 180) supplied with the expansion of the characteristic and with a second value (Qt+1) of the significant signal, and generating an approximate injection time (Tn) computed as a function of the expansion of the characteristic and of the second value of the significant signal. <IMAGE>
