An ignition apparatus is described for an internal combustion engine comprising: at least two sensors driven by the engine, the first one providing first and second detection outputs, respectively, at first and second crank angle positions of the engine, and the second one providing third and fourth detection outputs, respectively, at third and fourth crank angle positions of the engine; a first bistable means operable by the first and second detection outputs of a predetermined level from the first sensor; a second bistable means operable by the third and fourth detection outputs of a predetermined level from the second sensor; a third bistable means operable by one of the first and second detection outputs of a predetermined level and one of the third and fourth detection outputs of a predetermined level to produce a control output; means for combining the output signals of the first and second bistable means and providing logical combined signals representing ignition signals only when a sensor output exceeds a predetermined level to avoid erroneous ignition signals; means receiving the logical combined signals and the control output of the third bistable means; and means for distributing the logical combined signals into ignition signals corresponding to a predetermined number of cylinders.
