Abstract

Injecteur de carburant comprenant une tête (13) qui présente une face extérieure (20) libre et munie d'un orifice principal (21) adapté pour pulvériser un jet selon une direction (P) principale et un orifice secondaire (25) adapté pour pulvériser un jet selon une direction (S) secondaire, lesdits orifices debouchant dans la face extérieure et communiquant directement avec une chambre d'injection (24). La direction secondaire forme un angle α compris entre 100 et 80° avec la direction principale de manière à ce que le jet secondaire (26) intercepte le jet principal (22) dans une zone (30) d'éclatement qui débute à une distance d inférieure à 15 mm, et le débit du jet secondaire est compris entre 80 % et 100 % du débit du jet principal. La présente invention se rapporte également à l'utilisation d'un tel injecteur dans un moteur à allumage commandé et à la fabrication de cet injecteur.
