ROD-TYPE IGNITION TRANSFORMER INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To make a rod-type ignition transformer and an ignition unit in a condition that ultra miniaturization is possible and an ignition voltage up to 30 kV is induced by energy accumulated as little as possible by avoiding eddy current losses at a high changing speed of the magnetic flux. SOLUTION: A central coil core 3 is formed of a ferromagnetic powder composite material.
