IGNITION COIL FOR MULTIPLE IGNITION

摘要

PROBLEM TO BE SOLVED: To provide an ignition structure having optimum ignition conditions and control thereof in a combustion engine of a multiple ignition system.

SOLUTION: The ignition coil for multiple ignition has a structure in which a closed magnetic circuit is constituted by a center core formed by laminating silicon steel thin plates and an outer circumferential core formed by laminating silicon steel thin plates, a primary coil formed by coaxially winding a primary copper wire and a secondary core formed by winding a secondary copper wire are disposed on the center core, the primary coil and the secondary coil are housed in a case, and a magnet is attached on an air gap provided between a center iron core and an outer circumferential iron core in the combustion engine ignition coil injection-molded with an insulating resin.
