Abstract

L'invention concerne un circuit de la commande de temporisation d'un moteur à combustion, par exemple un circuit de commande d'allumage. Le circuit comprend un dispositif de détection 12 produisant un signal en créneau avec une période de 180 degrés pour un moteur à quatre cylindres. Un intégrateur 14 est remis à zéro par les parties d'allure croissante et décroissante de ce signal pour produire un signal en dents de scie ayant une période égale à 90 degrés de rotation du vilebrequin. Un circut d'ecrêtage ou de suppression 20 permet de doubler la période de ce signal en dents de scie qui est ensuite transmis avec un signal de temporisation désiré à un comparateur 16 dont la sortie est transmise à un dispositif d'allumage 22. L'invention concerne notamment les allumages électroniques de moteurs à combustion interne.
