Abstract

PURPOSE:To inhibit irregular combustion at the low-speed side while generating the maximum torque at the high-speed side, by controlling ignition timing so that an ignition lead angle characteristic be brought to an approximate step-like condition to the speed of revolution of an engine. CONSTITUTION:The output of a pulser-coil 8 charges a condenser 30 through a diode 29. Thus, the terminal voltage of the condenser 30 continuously increases with the rise of the speed of revolution. When the speed of revolution reaches the approximate center of a range of the rotation of an engine, a lag angle inhibit circuit 16 starts its functioning, and the action of a lag angle circuit 15 is inhibited. Consequently, ignition lead angle at the high-speed side approaches to an lead angle characteristic of a fundamental CDI device. The lead angle characteristic using the lag angle inhibit circuit 16 and the lag angle circuit 15 is brought to an approximate step-like condition. Thus, irregular combustion is inhibited because ignition timing is delayed at the low-speed side while the maximum torque can be generated because ignition timing approaches to the lead angle characteristic of the fundamental CDI device at the high-speed side.
