Abstract

L'appareil décrit comprend une mémoire morte 202 où sont tabulees en fonction de paramètres de régime du moteur des données représentatives de la richesse du mélange carburé. Au moyen d'un circuit logique 203 associé à un microprocesseur 201, ces données sont sélectionnées d'après les valeurs des paramètres de régime mesurées par des capteurs, et elles agissent sur des électro-vannes de dosage d'air 4 et de combustible 6, 8, 9 en assurant une régulation de richesse qui dépend du type de régime. En association avec une commande asservie par capteur d'oxygène 3, l'ouverture d'une vanne de recyclage des gaz brûlés 5 est réglée en fonction des valeurs de la vitesse de rotation et de la dépression d'admission avec encadrement par des limites dépendant de l'ouverture du papillon du carburateur 7.
