Abstract

Vengono descritti un procedimento ed un dispositivo per comandare un sistema di dosaggio del combustibile comandato da valvola magnetica specialmente per un motore diesel. In tal caso un dispositivo di comando elettronico partendo da almeno la durata della mandata determina l'istante di comando di chiusura A per una valvola magnetica. Correggendo il segnale FD della durata della mandata si possono preassegnare caratteristiche localmente decrescenti (Figura 2).A method and a device for controlling a fuel metering system controlled by a magnetic valve, especially for a diesel engine, are described. In this case, an electronic control device starting from at least the delivery duration determines the closing command instant A for a magnetic valve. By correcting the FD signal of the delivery duration, locally decreasing characteristics can be pre-assigned (Figure 2).
