Abstract

Ce dispositif utilise un injecteur unique 10 commandé électroniquement et disposé de façon à envoyer un jet de combustible dans la tubulure d'entrée 11 de l'air en amont du papillon 13 de régulation du débit d'air. L'injecteur 10 se trouve en regard d'un piston 16 de commande du débit d'air, qui se déplace en fonction des conditions d'écoulement de l'air dans la tubulure Ce piston 16 est associé à un transducteur 22, qui fournit un signal de commande pour un circuit de commande électronique 23, qui envoie des impulsions de marche à l'injecteur en synchronisme avec la marche du moteur, impulsions dont la durée dépend du signal de sortie de transducteur.
