Abstract
An ignition coil unit includes: an ignition circuit including a primary coil and a secondary coil; a power generator including a generator coil; a controller configured to control an ignition timing of the ignition circuit by an input signal generated by an induced voltage of the generator coil; and a sensor configured to input load information to the controller. The controller includes a memory configured to store working time information which corresponds to operating information based on the input information and the load information, as matrix data composed of the operating information, the load information and time data.
