Abstract

a. Circuit à seuil. b. Circuit caractérisé par un dispositif de stockage de charge 38 couplé à la première borne du détecteur pour donner un potentiel de courant continu dont l'amplitude est proportionnelle à l'amplitude des signaux de temps d'allumage, un amplificateur à gain unitaire 20 couplé à la seconde borne du détecteur et constitue une impédance faible pouvant varier en fonction des variations d'amplitude du potentiel appliqué par le dispositif de stockage de charge et un comparateur 22 dont une entrée est couplée à la première borne du détecteur et une sortie est couplée au circuit de commande de courant pour créer un signal de commande rendant conducteur le circuit d'entraînement de courant c. L'invention concerne les allumages électroniques de moteurs à combustion interne.
