    Abstract: The static correction device for advancing ignition controlled by an electromechanical or electronic detector incorporates a circuit for forming a signal received during the passage of a nonactive part of the cam and issuing a signal which partially charges a first condenser and discharges it during a time equal to the difference between the passage time of the nonactive part of the cam, and the charging time, a second charging condenser partially charging during a time inversely proportional to the speed during the passage of the nonactive part of the cam and completely discharging after that with a current proportional to the voltage at the terminals of the first condenser. The end of the discharge of the second condenser trips a temporization which is a function of the speed and interrupts the primary current of the ignition coil, by the intermediary of an amplifier circuit, so as to produce an induced current in the secondary of the ignition coil.
