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.The invention relates to an intake air flow sensor for an internal combustion engine. This detector includes a motor rotation angle detector 1, a shaping circuit 2, two monostable multivibrators 3 and 4, a flowmeter 5, a shaping circuit 6, a counter controlled by the second monostable multivibrator 4 , and a locking circuit reading the contents of the counter and controlled by the first monostable multivibrator 3. The invention makes it possible to simplify the arithmetic unit of an electronic injection system of a motor vehicle.
