Abstract

Carburateur comportant un passage d'admission alimenté en carburant par des réseaux doseurs comportant un réseau doseur principal et un réseau doseur de ralenti. Un montage électrique engendre, en réponse au signal de sortie d'un detecteur de composition des gaz d'échappement, ainsi qu'à d'autres paramètres de fonctionnement, des signaux qui assurent, par l'intermédiaire de transducteurs, une modulation contrôlée du dosage de carburant dans les réseaux principal et de ralenti. Application à la limitation de la pollution atmosphérique par les gaz d'échappement, sans augmentation de la consommation de carburant
