Abstract

Procédé d'obtention d'une avance automatique d'allumage pour moteur à combustion interne, notamment pour véhicules automobiles, caractérisé en ce qu'à partir d'une tension de référence V1, un générateur 9 délivre une tension en dent de scie V2, laquelle tension V2 est comparée dans un multicomparateur 10 à une pluralité de tensions de seuils et est transformée par un générateur 11 en une tension V3, de pente variable suivant la loi d'avance désirée, de manière que la tension V3, corrigée par l'intermédiaire d'un capteur 15, d'au moins un des paramètres de fonctionnement du moteur, soit appliquée à l'une des entrées d'un comparateur 13, lequel comparateur délivre un signal, lorsque les tensions V1 et V3 coïncident, à un circuit logique 14 commandant l'instant de déclenchement de l'étincelle d'allumage.
