Ignition control system |
摘要 |
An ignition control system is provided, which includes: an engine speed detector (101) for calculating an engine speed according to an engine crank angle signal (100); a current supply start controller (102) for outputting a proper current supply start timing signal corresponding to the engine speed to an ignition coil (5); a current supply finish controller (103) for outputting a proper current supply timing signal corresponding to the engine speed to an ignition coil; an ignition coil controller (104) for controlling supply of power to the ignition coil (5) according to the current supply start timing signal and the current supply finish timing signal; and an overspeed determination device (105) for outputting an overspeed determination signal when determining that the engine speed is in excess of a predetermined limit value. The overspeed determination signal prohibits starting the supply of current, and retards the current supply finish timing to such a degree as to decrease engine torque.
