Abstract

Circuit d'addition d'impulsion de durée pour système électronique d'injection de combustible dans lequel les injecteurs sont commandés par des impulsions dont les durées sont contrôlées en accord avec des informations reçues depuis divers senseurs associés au moteur ; une impulsion principale est transmise pour chaque révolution du moteur et cette impulsion est utilisée pour commander les injecteurs pendant la durée contrôlée; des impulsions auxiliaires d'enrichissement d'accélération sont aussi utilisées pour commander les mêmes injecteurs pendant une durée contrôlée par l'etat du papillon. Ce circuit d'addition agit de manière que la durée d'une impulsion auxiliaire soit ajoutée à la durée de l'impulsion principale même si cette impulsion auxiliaire survient pendant la durée de l'impulsion principale, de sorte que la quantité totale de combustible désirée se trouve ajoutee indépendamment de l'existence simultanée ou non de l'impulsion auxiliaire.
