Abstract

PURPOSE:To delay the discoloring of an exhaust by allowing the exhaust temp. to be reduced, by means of allowing the ignition time at the idling time to be led in angle than the ignition time at the starting time. CONSTITUTION:The outputs of a slow increasing type ignition angle of lead device 21 and an instant type ignition angle of lead device 22 are connected to a thyristor 19 in the ignition circuit. The angle of lead device 21 generates a mountain-like output as shown in the drawing (a), and the angle of lead device 22 generates an output as shown in the drawing (b) from a coil 25 between legs 26a, 26b. At the starting time of an engine 2, the voltage (a) is lower than the trigger voltage Vt of the thyristor 19, and only mountain part of the voltage (b) exceeds Vt, and at this time, the ignition is effected. At the idling time, the ignition time is led in angle by means of exceeding Vt by both sides mountain shape of the voltage (b). When it becomes to a high rotation, the voltage (b) becomes high, and the angle of lead is effected according as the rotation. By such means, the proceeding of the discoloring of the exhaust pipe can be possible by means of allowing the exhaust temp. to be reduced.
