Abstract

Vengono descritti un procedimento e un dispositivo per comandare un utilizzatore elettromagnetico 120, specialmente una valvola magnetica di un impianto di iniezione di un motore endotermico. I tempi di commutazione dell'utilizzatore elettromagnetico 120 vengono preassegnati in dipendenza di grandezze caratteristiche di esercizio nel corso del comando per definire l'inizio dell'iniezione e, oppure la fine dell'iniezione.(Figura 1).A method and a device for controlling an electromagnetic user 120, especially a magnetic valve of an injection system of an internal combustion engine, are described. The switching times of the electromagnetic user 120 are pre-assigned depending on the operating characteristics during the command to define the start of the injection and / or the end of the injection (Figure 1).
