Abstract

Il sistema comprende primi cilindri (3a) realizzati lungo un primo asse (Y), secondi cilindri (3b) realizzati lungo un secondo asse (Z), delle valvole di aspirazione (6) una per ogni cilindro, un collettore carburante (7), condotti di alimentazione (8) che sfociano in corrispondenza della testa del rispettivo cilindro, e degli iniettori (11) uno per ogni cilindro per iniettare carburante lungo un rispettivo condotto di alimentazione. Gli iniettori comprendono un ugello (18) nel quale è realizzato un foro di iniezione (23) definito lungo un asse (8) convergente sull'asse Iongitudinale (A) dell'iniettore secondo un angolo (?) Gli iniettori che alimentano i primi cilindri presentano l'asse del foro di iniezione convergente sulla valvola di aspirazione dei primi cilindri, mentre gli iniettori che alimentano i secondi cilindri presentano l'asse del foro d'iniezione convergente sulla valvola di aspirazione dei secondi cilindri. (Figura 2).
