Abstract

Un détecteur (1) à roue phonique (2) détecte le passage d'un ou plusieurs pistons par le point mort haut (p.m.h.) et est suivi par des circuits conformateurs d'impulsions (5) fournissant des signaux de sortie à changements de niveau successifs séparés par un intervalle de temps proportionnel à la vitesse de rotation du moteur chaque fois qu'un piston passe par le p.m.h. Une unité électronique de traitement et de commande (10) règle automatiquement l'avance à l'allumage. A chaque démarrage du moteur, le premier changement de niveau du signal délivré par le circuit conformateur (5) provoque l'emmagasinage d'énergie dans le primaire (W1) de la bobine d'allumage (T). Le second changement de niveau de ce signal produit une étincelle sur la bougie ou les bougies (CC) correspondante (s). Ainsi, l'angle de rotation du moteur avant la première explosion effective au démarrage est rendu minimal.A tone wheel detector (1) detects the passage of one or more pistons through the top dead center (pmh) and is followed by pulse shaping circuits (5) providing output signals at level changes successive times separated by a time interval proportional to the engine speed each time a piston passes through the pmh An electronic processing and control unit (10) automatically regulates the ignition advance. Each time the engine is started, the first change in the level of the signal delivered by the conforming circuit (5) causes energy to be stored in the primary (W1) of the ignition coil (T). The second change of level of this signal produces a spark on the candle or candles (CC) corresponding (s). Thus, the angle of rotation of the engine before the first effective explosion at start-up is made minimal.
