Abstract

L'invention porte sur un dispositif d'injection (20) d'une charge dans une chambre de combustion (4) d'un moteur à combustion interne et à allumage commandé, le dispositif (20) comprenant : • Un conduit de stratification (21) communiquant avec la chambre de combustion (4) à proximité d'électrodes d'une bougie d'allumage (7) ; • Une ligne d'amenée (22) d'un fluide entre le conduit de stratification (21) et une source (30) présentant une pression déterminée ; Le dispositif (20) est remarquable en ce qu'il comprend : • Un clapet anti-retour (23) entre la ligne d'amenée (22) et le conduit de stratification (21), pour permettre l'écoulement du fluide de la source (30) à la chambre de combustion (4), et ainsi y injecter la charge, uniquement lorsque la pression dans la ligne d'amenée (22) est supérieure à la pression dans le conduit de stratification (21) ; • Un système obturateur (24) pour mettre en communication fluidique la ligne d'amenée (22) avec la source (30) de fluide et/ou avec un canal d'admission (5b) du moteur.
