Title:
IGNITION DEVICE FOR INTERNAL-COMBUSTION ENGINE AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP3849649
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve the problem which occurs when a plug-side tube section made of ceramic is to be integrated with a coil-side tube section made of ceramic in an ignition device for an internal combustion engine, which is mounted in a cylinder head after the ignition plug and the ignition coil are integrated with each other.
SOLUTION: The plug-side tube section 51 in which a center electrode 22 is incorporated, and the coil-side tube section 52 on which either a primary winding 31 or a secondary winding 32 is wound, are formed separately, and then both sections 51, 52 are combined with each other. This shortens the overall lengths of the tubes 51, 52, thus preventing cracks and bends from occurring in firing, and dimensional accuracy after firing is improved.
