Abstract

PURPOSE:To control optionally an ignition-angle property by one pickup coil signal by using two integration circuits and a comparison circuit in the control of the ignition angle. CONSTITUTION:A pulse PS of a fixed angle is detected by the pickup coil PC and two wave-form shaping outputs obtained by a wave-form shaping circuit WS are supplied to the two integration circuits INT1 and INT2. A wave form X is integrated at a low level by the wave-form shaping output A and retained at a high level. A wave form Y is controlled similarly by the other wave-form shaping output. The point of time at which both wave forms X and Y accord with each other is detected by the comparator COMP and the ignition is controlled by the logic sum with the pulse A. As the properties of the ignition angle, a fixed electrification rate and a step-form characteristic are obtained other than the property shown by (g) in the Figure, which changes gradually. By this constitution, the properties of the ignition angle can be controlled optionally by a signal from one pickup coil.
