Abstract

La présente invention concerne un moteur (1) à combustion interne à allumage par compression et à charge de carburant essence en partie pré-mélangée comprenant une chambre (6) de combustion reliée à une ligne (12) d’admission d’air, une soupape (10) d’admission et une soupape (14), des moyens d’injection de la charge en carburant comprenant un premier injecteur (17) de carburant injectant directement dans la chambre (6), des moyens (23) de commande du fonctionnement du moteur, caractérisé en ce que les moyens d’injections comprennent un second injecteur (19) de carburant placé dans la ligne (12) d’admission, les moyens (23) de commande pilotent le second injecteur (19) pour injecter une partie de la charge en carburant de sorte qu’elle entre dans la chambre (6) de combustion pendant la phase d’admission, puis pilotent le premier injecteur (17) pour injecter le reste de la charge en carburant dans la chambre (6) de combustion lorsque les soupapes sont fermées.
