Abstract
L'invention porte sur un injecteur pour moteur à combustion interne, à vaporisation du carburant, comportant: au moins un passage capillaire d'écoulement (12) présentant une extrémité d'entrée (14) et une extrémité de sortie (16) et comprenant un canal usiné dans un bloc monolithique d'un matériau choisi parmi des céramiques, des polymères, des métaux ou des composites en étant faits, ou dans un bloc multicouche de céramique; une soupape (18) de régulation de débit reliant l'extrémité d'entrée du passage (12) à une source de carburant et introduisant le carburant à l'état sensiblement liquide dans le passage (12); une source de chaleur (20) disposée le long du passage capillaire (12) et portant le carburant liquide présent dans le passage à une température suffisante pour le vaporiser au moins en partie et l'éjecter sensiblement vaporisé par l'extrémité de sortie du passage capillaire.
