Abstract

La présente invention concerne un dispositif de commande du taux air-carburant dans un carburateur. Dans un ensemble comprenant un carburateur 10 pour régler le taux air-carburant fourni à un moteur à combustion interne 22, un détecteur 25 est positionné dans la tubulure d'échappement pour fournir un signal relatif à l'un des constituants gazeux d'échappement. Un circuit de commande 30 permet la régulation de la position d'un élément 15 du carburateur pour modifier le taux air/carburant en fonction du signal de commande fourni par le détecteur 25. Ce composant du carburateur est déplacé de façon continue vers un etat de mélange plus riche ou plus pauvre. Le fonctionnement du circuit est modifié en fonction de la vitesse du moteur et de sa température. Application à la réalisation d'une régulation électronique automatique particulièrement simple pour véhicules automobiles.The present invention relates to a device for controlling the air-fuel ratio in a carburetor. In an assembly comprising a carburetor 10 for adjusting the air-fuel ratio supplied to an internal combustion engine 22, a detector 25 is positioned in the exhaust manifold to provide a signal relating to one of the exhaust gas constituents. A control circuit 30 allows the position of an element 15 of the carburetor to be regulated in order to modify the air / fuel ratio as a function of the control signal supplied by the detector 25. This component of the carburetor is continuously moved to a state of. richer or poorer mixture. The operation of the circuit is modified according to the speed of the motor and its temperature. Application to the production of a particularly simple automatic electronic regulation for motor vehicles.
