Abstract

L'invention a pour objet un appareil servant à détecter et à comptabiliser les auto-allumages d'un moteur à explosion. Un génerateur de courant continu 22 relié à la bougie 17 du cylindre sous contrôle fait apparaître à chaque explosion une impulsion en 23. Grâce à un circuit électronique 34, 43, un compteur 45 compte le nombre total de phases de relèvement formées chacune de cycles actifs (avec étincelles) et de cycles passifs (sans étincelles) et un compteur 47 compte le nombre de phases où au moins un auto-allumage a été relevé au cours de cycles passifs.
