Abstract
An ignition system for an internal combustion engine, in which system a position detector cooperates with an element driven in proportion to engine speed and supplies signals after shaping thereof, to a tachometric generator, the generator feeding an integrator which supplies a first voltage representative of the angular spacing from a reference position of said element, an amplifier in series with the integrator and supplying a second voltage as a function of engine speed, and a comparator receiving the sum of the first and second voltages and comparing it with a threshold voltage such that when said sum coincides with the threshold voltage, the comparator supplies an output signal used to trigger current in the ignition coil.
