Abstract

L'invention concerne un procédé et un dispositif de régulation d'énergie dans un système d'allumage pour un moteur à combustion interne. Ce dispositif comprend une bobine d'allumage ou un transformateur d'allumage produisant une tension d'allumage et présentant un enroulement primaire et un enroulement secondaire. L'enroulement primaire peut être court-circuité au moyen d'un commutateur, désigné sous l'appellation de court-circuiteur, et un courant ionique peut être mesuré à travers l'enroulement secondaire, au moyen d'une ou plusieurs bougies d'allumage. Le courant primaire est mesuré dans la phase de court-circuitage du court-circuiteur au moyen d'un élément approprié, puis acheminé à l'unité de commande. Après actionnement du court-circuiteur, la grandeur mesurée est traitée sous forme d'une fonction ou d'un filtrage dans l'unité de commande pour former une caractéristique qui sert à mettre en place une régulation d'énergie en fonction du temps et de l'angle de fermeture.
