Abstract

Il sistema di controllo dell'iniezione comprende una serie di mappe che consentono di determinare varie grandezze di iniezione (Q, P, ANT, ET) in base alla richiesta di potenza (V?) e al regime del motore (N). A regime, viene inizialmente calcolala la quantità di combustibile da iniettare (Q), in base a questa vengono calcolati la pressione di iniezione (P) e l'anticipo (ANT), mentre la durata dell'iniezione (ET) viene calcolata in base alla quantità di combustibile e alla pressione di iniezione. La pressione di iniezione viene controllata ad anello chiuso (30) controllando il duty-cycle della corrente di alimentazione di una elettrovalvola regolatrice di pressione (7) collegata alla pompa ad alta pressione (6).Figura 1.
