Abstract
PURPOSE: To reduce the unevenness of advance characteristic of each cylinder and permit the control through only a single system by making a circuit for obtaining advance characteristic in single system and allowing the distribution to each cylinder through a logic circuit.
CONSTITUTION: The output of a first pulser 3 generates a voltage for determining the maximum advance value of spark position and a voltage for determining the minimum advance value through the spark signal of a first cylinder. The output of a second pulser 4 generates the spark position standard signal for a second cylinder as well. Due to the logic product of the outputs of a first and a second flip-flops 5 and 6 which are driven by the output of F/F which are driven by the outputs of the first and the second pulsers, the spark signals of the first cylinder and that of the second cylinder are obtained. Accordingly, the first and the second triangular- wave generating circuits 9 and 10 for obtaining advance characteristic and a comparison circuit 11, irrespective of multicylinder, can be operated through a single system, and the unevenness of advance characterisitic of each cylinder is eliminated.
