Title: Plug tube and igniter of internal combustion engine
Inventor: OYABU SHINJI
IPC: F02P15/00
Filed: 1994-11-17
Abstract: PURPOSE: To provide a plug tube and an igniter of an internal combustion engine, having no adverse effect to the secondary voltage of an ignition coil with an open magnetic circuit structural high-voltage generating circuit. CONSTITUTION: An igniter 1 consists of an ignition coil 2 and a plug tube body 10. This plug tube body 10 housing the ignition coil 2 being formed in a cylindrical shape is made up of winding a silicon steel plate of 0.5mm in thickness, by way of example, into cylindrical form. Since length in the winding direction of the plate is set to be such as extent that both winding start and finish ends of the plug tube body 10 are not contacted with each other, a slit is formed up. Owing to this slit, even if the plug tube body 10 constitutes a part of a magnetic circuit of the ignition coil 2, there is no closed circuit electrically, so an eddy current will not flow in the circumferential direction of a cylindrical part. Therefore, any eddy current loss due to the plug tube body 10 is not produced at all, and thus there is such an effect as preventing any reduction in the secondary voltage of the ignition coil to be housed in the plug tube body 10.

Filed: 1988-11-11
Abstract: PURPOSE:To make it possible to assembly easily and fix uniformly without deformations such as twist after winding by forming by a wire material elastically deformed and coils whose wires sizes of the winding section and the winding end section differ. CONSTITUTION:Wires are wound on a coil guide of a coil holding jig. A core 10 is inserted into it, and the coil holding jig is pulled out by pressing a winding against the winding groove 11 of the cylindrical core 10. The wire material provides 0.5 to 20% extension in the range of elasticity. The wire sizes b, c of the winding section is a size 80 to 99.5% of a wire size (a) of the winding end section. The degree of the extension of the wire material becomes equal at the same position on a circumference in windings having two or more turns, and the change tendency of the wire size becomes the same. Thus, magnetic characteristics can be made uniform. Further, since wire materials are elastically deformed, coils can be installed in a core winding groove uniformly and floating can be prevented.
