Abstract

Injecteur ouvert pour moteur à combustion interne. L'invention améliore la construction de la sortie de l'alésage d'injecteur, influe sur la forme du jet de carburant en fonction du débit d'injection et fournit ainsi un allumage sûr et une combustion totale du mélange, grâce au fait que, en direction du côté sortie, l'alésage d'injecteur comporte un évidement s'élargissant constamment, de préférence sous forme linéaire ou courbe, de sorte que la sortie d'alésage d'injecteur est asymétrique, l'évidement pouvant être de forme ovale, rectangulaire ou arrondie, ou pouvant correspondre à deux cercles entrant ou non en correspondance l'un avec l'autre. Application aux moteurs à injecteur ouvert en général.Open injector for internal combustion engine. The invention improves the construction of the outlet of the injector bore, influences the shape of the fuel jet depending on the injection rate and thus provides safe ignition and total combustion of the mixture, thanks to the fact that, towards the outlet side, the injector bore has a constantly widening recess, preferably in a linear or curved form, so that the injector bore outlet is asymmetrical, the recess may be oval in shape , rectangular or rounded, or which can correspond to two circles entering or not in correspondence with each other. Application to engines with open injectors in general.
