Abstract

L'invention concerne les moteurs à explosion. Elle a pour objet un injecteur 10 doté d'une buse 13 à deux ajutages 16, 17 d'admission d'essence Les axes de ces ajutages convergent, de sorte que les jets d'essence se heurtent et se fractionnent en fines gouttelettes. Application à l'amélioration de l'injection d'essence dans les moteurs à explosion.The invention relates to internal combustion engines. Its object is an injector 10 provided with a nozzle 13 with two gasoline inlet nozzles 16, 17 The axes of these nozzles converge, so that the gasoline jets collide and split into fine droplets. Application to the improvement of gasoline injection in internal combustion engines.
