Title (EN) IGNITION CAPACITIVE DISCHARGE SYSTEM FOR INTERNAL COMBUSTION ENGINES
(FR) SYSTEME DE DECHARGE D'ALLUMAGE A CONDENSATEUR POUR MOTEURS A COMBUSTION INTERNE
Abstract:
(EN) An ignition capacitive discharge system for internal combustion engines particularly of small sizes, two-stroke cycle 'OTTO', associable with one rotary generator of electric energy to produce an ignition signal for spark plug means (Ca), supplied directly from the supply bobbin of the discharge capacitor (C1), utilizing as discharge means of said discharge capacitor (C1) a Thyristor (SCR = Silicon Controlled Rectifier), characterized in that the pilotage of said thyristor (SCR) is operated on its cathode by a high impedance branch with the gate (G) of said Thyristor (SCR) electrically connected to mass (Fig. 4, 5, 6).
(FR) Un système de décharge d'allumage à condensateur pour moteurs à combustion interne, particulièrement de dimensions réduites, à deux temps et à allumage par étincelle, pouvant s'associer à un générateur rotatif d'énergie électrique pour produire un signal d'allumage pour des bougies (Ca), alimenté directement par la bobine d'alimentation du condensateur de décharge (C1), utilisant, comme moyen de décharge dudit condensateur (C1), un thyristor (SCR: redresseur de silicium), caractérisé par le fait que le pilotage dudit thyristor SCR s'effectue sur sa cathode par une branche à haute impédance avec la grille (G) dudit thyristor SCR reliée électriquement à la masse.
