Abstract
(EN)
An electronic ignition system for an internal combustion engine comprises an ignition coil (2) provided with at least a primary winding (3) and a secondary winding (4), a switch (6) connected to the primary winding (3) and drivable in an open and/or closed position according to the value of a driving signal, a control unit (7) associated to the switch (6) and configured to drive it in open and/or closed position according to the value of the driving signal (G). Such system also comprises a voltage changing electronic element (8) connected to the electrical connection (5), operatively interposed between the electrical connection (5) and the primary winding (3), and configured to change the voltage value of the primary winding (3) according to the value of a control signal between at least a first (V1) and a second (V2) voltage value. The control unit (7) is associated with the changing electronic element (8) and configured to generate the control signal (C) variable at least between a first value and a second value respectively representative of the first (V1) and the second (V2) voltage value of the primary winding (3) and send the changing electronic element (8) the control signal (C) having the first value at least during a first charging interval of the primary winding (3).

L'invention concerne un système d'allumage électronique pour un moteur à combustion interne, lequel système comprend une bobine d'allumage (2) comportant au moins un enroulement primaire (3) et un enroulement secondaire (4), un commutateur (6) connecté à l'enroulement primaire (3) et pouvant être actionné dans une position ouverte et/ou fermée en fonction de la valeur d'un signal d'actionnement, et une unité de commande (7) associée au commutateur (6) et conçue de façon à l'actionner dans une position ouverte et/ou fermée en fonction de la valeur du signal d'actionnement (G). Ce système comprend également un élément électronique de changement de tension (8) connecté à la connexion électrique (5), interposé de manière fonctionnelle entre la connexion électrique (5) et l'enroulement primaire (3), et est conçu pour changer la valeur de tension de l'enroulement primaire (3) en fonction de la valeur d'un signal de commande entre au moins une première (V1) et une seconde (V2) valeurs de tension. L'unité de commande (7) est associée à l'élément électronique de changement (8) et est conçue pour générer le signal de commande (C) variable au moins entre une première valeur et une seconde valeur respectivement représentatives de la première (V1) et de la seconde (V2) valeur de tension de l'enroulement primaire et pour envoyer à l'élément électronique de changement (8) le signal de commande (C) ayant la première valeur au moins pendant un premier intervalle de charge de l'enroulement primaire (3).
