Abstract

L'invention concerne un détecteur de débit d'air d'admission pour un moteur à combustion interne. Ce détecteur comprend un détecteur 1 d'angle de rotation du moteur, un circuit de mise en forme 2, deux multivibrateurs monostables 3 et 4, un débitmètre 5, un circuit de mise en forme 6, un compteur commandé par le second multivibrateur monostable 4, et un circuit de verrouillage lisant le contenu du compteur et commandé par le premier multivibrateur monostable 3. L'invention permet de simplifier l'unité arithmétique d'un système d'injection électronique de véhicule automobile.
