Title
(EN) INTERNAL COMBUSTION ENGINE IGNITION DEVICE
(FR) DISPOSITIF D'ALLUMAGE POUR MOTEUR A COMBUSTION INTERNE
Abstract
(EN)
The device comprises an a.c. voltage source (5, 6, 7), a resonant circuit (Lf, Cs) coupled to a transformer (9) and a plug (10) which is supplied under high tension by the resonant circuit. An oscillator (11) controls the frequency of the voltage source. Means (14) are provided for detecting the resonant frequency of the circuit (Lf, Cs) and for tuning the oscillator to this frequency during priming. The device further comprises means (13) for adjusting the frequency of the oscillator, after the priming, to a value ensuring the sustaining of the arc and means (15) for cutting this arc after the elapse of a predetermined period.
(FR)
Le dispositif décrit comprend une source de tension de courant alternatif (5, 6, 7), un circuit à résonance (Lf, Cs) couplé à un transformateur (9) et une prise de connexion (10) qui est alimentée sous haute tension par le circuit à résonance. Un oscillateur (11) commande la fréquence de la source de tension. Un organe (14) est prévu pour détecter la fréquence de résonance du circuit (Lf, Cs) et pour syntoniser l'oscillateur à cette fréquence pendant l'amorçage. Le dispositif comprend en outre un organe (13) servant à régler la fréquence de l'oscillateur, après l'amorçage, à une valeur assurant le maintien de l'arc, ainsi qu'un organe (15) servant à interrompre cet arc, une fois passée une période prédéterminée.
