Abstract

Ce dispositif d'allumage pour moteur à combustion interne empêche la formation des étincelles lorsque la température du moteur dépasse un niveau prédéterminé. Le circuit d'allumage comprend un transistor d'entrée 1 qui est commuté par un récepteur 44 recevant des impulsions du moteur. Le transistor d'entrée 1 contrôle la charge et la décharge d'un condensateur 5 dont le voltage détermine si la commutation du transistor d'entrée 1 permet la formation d'une étincelle par l'intermédiaire d'un amplificateur de sortie et d'une bobine d'allumage 35. Un élément 2 sensible à la température détermine à la fois la valeur à laquelle le condensateur 5 peut être chargé et le voltage final auquel il peut être chargé. Application aux moteurs d'automobiles.
