Title:
IGNITION APPARATUS FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2001006953
Kind Code:
A
Abstract:
To improve productivity of a center core and also improve magnetic flux conversion efficiency.
This ignition apparatus can improve productivity and also improve magnetic flux conversion efficiency, by using thin film amorphous alloy in the plate thickness of 0.1 mm or less and magnetic flux density B8≥1.4 T in the DC magnetization force of 800 A/m or a silicon steel plate in the thickness of 0.23 mm or less as the material of center core, and by employing an eddy structure in the structural elements such as primary coil 2, secondary coil 4, center core 6 and side core 7 or the like.
