Abstract

Dispositif dans lequel on ajoute à l'impulsion de référence R et à l'impulsion d'étincelle F de chaque cycle une impulsion supplémentaire E, et dans lequel on fait apparaître une impulsion différentielle du second ordre entre les écarts mutuels des impulsions R, F et E. L'impulsion de référence R est liée à la rotation du vilebrequin, l'impulsion F est produite par la haute tension d'allumage et l'impulsion E provient du traitement des deux précédentes dans un multivibrateur. V1 résulte de la différence entre les instants d'apparition de E et de R, V2 résulte de la différence entre E et F, l'impulsion V1 -V2 est l'écart entre V1 et V2 . Cette dernière impulsion détermine l'instant d'allumage.
