Abstract

CE DISPOSITIF EST DU TYPE DE CEUX DANS LESQUELS L'INTERRUPTION DU COURANT DANS L'ENROULEMENT PRIMAIRE D'UNE BOBINE D'ALLUMAGE PRODUIT DANS L'ENROULEMENT SECONDAIRE DE CELLE-CI LA TENSION ELEVEE NECESSAIRE A LA FORMATION DES ETINCELLES. IL EST CARACTERISE EN CE QUE LE PASSAGE DU COURANT EST AMORCE PAR DES MOYENS DE COMMANDE NUMERIQUES, COMPRENANT UNE MEMOIRE NUMERIQUE 13 PROGRAMMEE DE FACON EMPIRIQUE, UN COMPTEUR 14, UNE SOURCE D'IMPULSIONS D'HORLOGE 15 ET UN CIRCUIT DE COMMUTATION 16, POUR BASCULER UN CIRCUIT BISTABLE 17 DANS L'ETAT OU IL EXCITE L'ENROULEMENT PRIMAIRE A UN MOMENT DU CYCLE DU MOTEUR QUI EST DETERMINE PAR LE SIGNAL DE SORTIE DE LA MEMOIRE. UN DISPOSITIF A TEMPORISATION FIXE 18 BASCULE LE CIRCUIT BISTABLE DANS SON AUTRE ETAT STABLE, DANS LEQUEL IL INTERROMPT LE PASSAGE DU COURANT DANS LE PRIMAIRE.
