Abstract
PURPOSE: To obtain a variety of delayed ignition timing characteristics by arranging a delayed ignition signal generating circuit which is operated through the reception of main ignition signal and controlling the ratio of charge and discharge currents for charge and discharge by means of the constant current of the condenser of this circuit according to the operation state.
CONSTITUTION: The ignition timing controlling circuit is equipped with an ignition controlling circuit A consisting of a main ignition signal generating circuit 1, amplifying circuit 2 which amplifies the output, and an ignition circuit 3 which is controlled by the output signal of the amplifying circuit. The ignition timing controlling circuit is also equipped with a delayed ignition signal generating circuit B containing a trigger circuit 7 which generates a trigger signal according to the output signal of the circuit 1, bi-stable multivibrator 8 which is driven in one direction by the output signal, triangular-wave forming circuit 9 constituted of the constant current charge and discharge circuit of a condenser Q, and an output circuit 10. In this case, the apparatus is constituted so that the ratio of the charging current and the discharging current of the constant current charge and discharge circuit of the condenser Q can be controlled by the signal corresponding to the engine operation state applied from outside signal terminals h1 and h2.
