INTERNAL COMBUSTION ENGINE IGNITION DEVICE

Title:

INTERNAL COMBUSTION ENGINE IGNITION DEVICE

Document Type and Number:

WIPO Patent Application WO/2014/163071

Kind Code:

A1

Abstract:

This internal combustion engine ignition device, which does not have a battery, is capable of reliably providing ignition from the very start of the rotation of an engine, and prevents the excessive generation of ignition energy. The internal combustion engine ignition device has a core (12), a coil part (L) that is wound over the core, and a secondary coil (L2) that is wound on the outer peripheral side of the coil part. A switching element (Tr) switches an induced current, which is generated via the rotation of a permanent magnet, of a primary coil on and off. A resistor (R1) and a microcomputer (42) are connected to the switching element, and a rotation detection circuit (41) 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 (22) connected to the secondary coil. In the coil part (L), one coil is divided by an intermediate tap (Tap), forming the primary coil (L1) and a charging coil (LCH).
