Abstract

L'invention a pour objet un circuit de commande des injecteurs du carburant sur un moteur à combustion interne. Dans un passage il d'aspiration d'air est monté un piston 12 portant une fourche 14 dont les deux branches contiennent un organe tournant 21 ayant une ouverture profilée; les branches portent respectivement une source lumineuse et un élément opto-électronique dont les signaux sont envoyés à un processeur numérique qui émet en fonction de la vitesse du moteur des impulsions commandant l'instant et la durée d'ouverture des injecteurs. L'invention est utile sur tout moteur à injection.
