Abstract

Procédé de contrôle de dosage du mélange air-carburant dans le carburateur d'un moteur à combustion interne. Le procédé consiste essentiellement à commander périodiquement l'interruption de l'admission du carburant pendant des durées qui sont fonction décroissante d'un signal représentatif de l'instabilité instantanée du moteur d'une part, et d'un signal représentatif de l'instabilité moyenne du moteur d'autre part. Application aux dispositifs économiseurs de carburant.
