Claims

[Scope of utility model registration request]

reference signal output means for outputting a reference signal at every predetermined crank angle of the engine; synchronization control means for igniting an ignition plug in synchronization with the input timing when the reference signal is input; and a measured time from the input of the reference signal. time control means for igniting the ignition plug based on;
a rotational speed detection means for detecting the engine rotational speed; a rotational speed determination means for determining whether the detected engine rotational speed is equal to or higher than the switching rotational speed; and said synchronization control means when the engine rotational speed is less than the switching rotational speed. an actuating means for actuating the time control means when the engine rotational speed is equal to or higher than the switching rotational speed; An ignition timing control device for an internal combustion engine, comprising: control switching means that switches to the time control means and operates the time control means after a period of continuation.
