Abstract

Cette invention concerne la gestion du processus de combustion du carburant dans la chambre de combustion d'un moteur à combustion interne, laquelle gestion se fait par mesure du courant ionique du système d'allumage. Le système d'allumage comprend une unité de commande (1), un élément à décharge (2) et un canal d'allumage (3). Ce canal d'allumage comprend à son tour un contacteur électronique (4) dont la sortie de commande est reliée à la sortie de l'unité de commande (1), une bobine d'allumage (5), une diode (6) et un condensateur de mesure (7). La particularité du système d'allumage tient au fait que le canal (3) est équipé d'une résistance (9) de mesure du courant qui est connectée entre l'électrode du condensateur (7) et la masse du moteur à combustion interne. L'unité de commande (1) comporte des entrées (10 et 11), la première étant connectée au point de connexion du condensateur (7) et de la résistance (9), tandis que la seconde est connectée au point de connexion de la bobine (5) et du contacteur (4). Un condensateur (8) peut également être connecté en parallèle aux spires de l'enroulement primaire de la bobine (5). Afin de gérer le processus de combustion du carburant, des oscillations de courant magnétique sont générées dans la bobine (5) en faisant passer un courant dans l'enroulement primaire, tandis que l'on crée, dans le circuit de l'enroulement secondaire, des impulsions de tension ayant des paramètres prédéterminés et qui serviront à charger le condensateur (7). Le courant ionique passant par les électrodes de l'élément à décharge (2) est mesuré et considéré comme la valeur de courant de charge du condensateur (7).
