Abstract
Dispositif d'alimentation pour moteur à combustion interne à charge stratifiée du type comportant deux conduits d'admission de mélange, dont l'un est relativement plus pauvre que l'autre, dans la chambre de combustion. Les deux conduits d'admission 12, 13 débouchent l'un au-dessus de l'autre dans la chambre de combustion 2 par une unique soupape d'admission 3 commandée par une came d'admission 8 dont le profil lui imprime une levée en deux temps, ladite soupape d'admission 3 comportant au niveau de sa tige 14 un moyen d'obturation 15 du conduit d'admission superieure 12 d'ouverture décalée par rapport à celle de sa tête 17 en fonction du profil à double levée de ladite came d'admission 8. Application aux moteurs à combustion interne à charge stratifiée, et plus particulièrement aux moteurs de ce type destinés à équiper des véhicules automobiles.
