<p>1. Electronic device for controlling the ignition of an internal-combustion engine, in particular for motor vehicles, the said device comprising a magnetic generator (1) consisting of a rotor (2) and of an armature winding (3) supplying alternating signals which are applied, by means of resistors (4, 5, 6), to inputs (7, 8) of a control circuit (9) of an electronic switch (10) controlling the passage of a current through the primary winding (11) of an ignition coil (12), to supply a spark of constant energy to spark plugs (15, 16, 17, 18) connected consecutively to the secondary winding (13) of the coil (12) by means of a distributor (14), the said device being characterized in that a capacitor (21) is connected between the end (6a) of the resistor (6) and the input (8) of the circuit (9), in such a way that the variation in impedance of the capacitor (21) compensates the advance of the ignition point caused by the generator (1) in the range of its low rotational speeds.</p> |
