Abstract

Dispositif d'injection de carburant La vitesse de débit du carburant est augmenté par suite d'un élément de pompe 1 plus important ou par une rampe plus raide de la came de pompe 2 de sorte que l'aiguille 9 de l'injecteur 6 s'ouvre plus vite et complètement au ralenti et à de faibles charges afin d'accroître la pression et la vitesse d'injection au niveau du canal d'injection. Moteurs à combustion interne.Fuel injection device The fuel flow speed is increased as a result of a larger pump element 1 or by a steeper ramp of the pump cam 2 so that the needle 9 of the injector 6 s '' opens faster and fully at idle and low loads to increase injection pressure and speed at the injection channel. Internal combustion engines.
