Abstract

Il sistema (1) comprende una pluralità di circuiti di attuatore includenti ciascuno un condensatore (Ci) ed un primo interruttore controllato (SWi) interposto fra la bobina di un iniettore (Li) ed una linea di riferimento per consentire l'alimentazione dell'iniettore (Li) da parte del condensatore. Un secondo interruttore controllato (SWR) è interposto fra una linea dei condensatori ed una linea di alimentazione (104) degli iniettori. Il sistema (1) comprende una centralina elettronica (12) la quale è atta a controllare la commutazione del primo (SWi) e del secondo (SWR) interruttore al fine di fornire agli iniettori una corrente presentante una zona ad ampiezza elevata con rapido fronte di salita, una zona con crescita lenta ed una zona con ampiezza oscillante intorno ad un valore medio.[Fig. 1, 3].
