The present invention refers to an apparatus for raising the spark energy in capacitive ignition systems comprising at least one charge winding (L1) which via a first rectifier device (D1) charges a charge capacitor (C1) connected to the primary winding of an 5 ignition voltage transformer in order to provide said primary winding with energy for generation of a spark characterised in that additionally a second rectifier device (D2) and a switching device (Q2) are arranged in such a way that the switching device periodically can short circuit the charge winding and thereby increase the charge of the charge capacitor at low engine speeds.
La présente invention concerne un appareil pour faire augmenter l'énergie d'étincelle dans des systèmes d'allumage capacitifs comprenant au moins un enroulement de charge (L1) qui, via un premier dispositif rectificateur (D1), charge un condensateur de charge (C1) connecté à l'enroulement primaire d'un convertisseur de tension d'allumage afin de fournir audit enroulement primaire, de l'énergie pour produire une étincelle, se caractérisant en ce qu'un second dispositif rectificateur (D2) et un dispositif de commutation (Q2) sont en outre disposés de sorte que le dispositif de commutation peut périodiquement court-circuiter l'enroulement de charge et ainsi faire augmenter la charge du condensateur de charge lorsque le moteur fonctionne à des vitesses faibles.
