Abstract

Un dispositif d'injection de carburant pour moteurs à combustion interne allumé par étincelle distribue une quantité dosée de carburant entraînée dans un gaz à l'intérieur de la chambre de combustion. L'injecteur présente une lumière (11) et une soupape (15), susceptible de se déplacer par rapport à la lumière (11), et qui présentent des faces d'échantéité annulaires respectives (13 et 18) définissant une gorge annulaire (25) tronconique lorsque l'injecteur est ouvert. L'injecteur présente un bouclier (20) s'étendant à partir de la lumière (11) et entourant la soupape (15) lorsque l'injecteur est ouvert et définissant un passage de distribution (27) en aval de la gorge, en direction de la chambre de combustion. Le passage de distribution (27) est conformé de manière à être purgé de carburant après chaque cycle de distribution de carburant pour empêcher la formation de calamine dans l'injecteur. Application aux moteurs équipant les véhicules de tous types, notamment les hors bords et automobiles.
