Abstract

Viene proposto un procedimento per l'esercizio di un motore a combustione interna, a più cilindri, a compressione d'aria, in cui il carburante, alimentato da una pompa ad alta pressione viene alimentato ad almeno un condotto di alimentazione ad alta pressione, comune per: tutti i cilindri e da esso viene alimentato sotto il controllo di valvole magnetiche, secondo una prestabilita successione di iniezioni, agli ugelli coordinati ai cilindri, in cui un impulso di sincronizzazione coordina l'iniezione di un determinato ugello ad un prestabilito cilindro e in cui inoltre un sensore di pressione, disposto nel condotto di alimentazione ad alta pressione rileva il valore di pressione di un determinato punto di esercizio giacente nel percorso di alimentazione e in caso di una differenza dal valore di pressione nominale, la pressione viene aggiustata attraverso una unità di controllo elettronica nel circuito di regolazione ad alta pressione, mentre in caso di mancanza dell'impulso di sincronizzazione il valore di pressione rilevato dal sensore di pressione di un determinato punto di esercizio giacente nel percorso di alimentazione, viene utilizzato per l'azione-
