Abstract

L'invention appartient au domaine de l'industrie automobile et concerne plus particulièrement des systèmes à étincelles des moteurs à combustion interne. L'invention permet d'améliorer la fiabilité de fonctionnement d'un moteur, notamment dans des conditions de basses températures et d'humidité élevée. Dans le système d'allumage, la bobine d'allumage est fabriquée de manière à ce que la résistance d'ondes ς du contour d'oscillation, formé par l'inductance et la capacité de charge effective dans le bobinage secondaire, compte tenu des courants de fuite, se situe dans l'intervalle 1,4 . Uperc/Isup < ς < 4,5 . Uperc/Isup, Uperc étant la valeur minimale de la tension dans un intervalle de décharge dans lequel le percement se produit de façon garantie, et Isup est le courant maximal admissible de la décharge d'étincelles lors duquel l'étincelle ne se transforme pas en une décharge en arc basse tension. La valeur de la résistance d'onde ς dans l'intervalle en question se concorde avec les paramètres de la décharge d'étincelles (la tension de percement et le courant de décharge), ce qui réduit les pertes d'énergie indésirables dans le système d'allumage et augmente la puissance de l'étincelle.
