Abstract

See full text

The internal combustion engine ignition device has a core, a coil part that is wound over the core, and a secondary coil that is wound on the outer peripheral side of the coil part. A switching element switches an induced current, which is generated via the rotation of a permanent magnet, of a primary coil on and off. A resistor and a microcomputer are connected to the switching element, and a rotation detection circuit is connected to the microcomputer. The microcomputer drives the switching element so as to rapidly change the current flowing through the primary coil and generate a high voltage in the secondary coil, and generate a spark discharge in a spark plug connected to the secondary coil. In the coil part, one coil is divided by an intermediate tap, forming the primary coil and a charging coil.
