Abstract

Improvements in ignition systems for internal combustion engines of motor vehicles, of the type comprising in particular an ignition switch, a saturable transformer that charges at least one capacitor, which is discharged through the primary of a booster coil voltage, by means of a thyristor from the opening of the ignition switch, characterized in that the command of the principle of current circulation in the saturable transformer and the command of the principle of discharge of the capacitor through the primary of the lift coil Voltages are made simultaneously with the opening of the ignition switch so that the capacitor is completely discharged before the energy transfer between the transformer and the capacitor takes place.
