Abstract

Injecteur de combustible liquide. On prévoit dans le corps 1 de l'injecteur au moins quatre alésages 6 sensiblement parallèles les uns aux autres et formant un angle alpha avec l'axe longitudinal X de l'injecteur, l'intervalle entre les différents alésages d'injection 6 a été réduit au point de créer sensiblement un seul jet de carburant et la section transversale de l'injecteur à canal unique utilisé habituellement dans le procédé de formation de mélange et de combustion connu et décrit Moteurs à combustions interne par compression d'air et injection directe.Liquid fuel injector. There is provided in the body 1 of the injector at least four bores 6 substantially parallel to each other and forming an angle alpha with the longitudinal axis X of the injector, the interval between the various injection bores 6 has been Reduced to the point of creating substantially a single jet of fuel and the cross section of the single channel injector commonly used in the known and described mixing and combustion process for internal combustion engines by air compression and direct injection.
