摘要： An internal combustion engine ignition device has a resin layer in a clearance between an insulator and a winding contained in the insulator. The ignition device has a cylindrical insulator and a resin layer. The insulator has an opening portion at one end and a bottom portion at the other end. The insulator contains one of a primary winding and a secondary winding. The resin layer is formed by charging a resin in the clearance between the insulator and one of the windings. The diameter of the inner periphery of the insulator gradually increases from the opening portion to the bottom portion. When the resin layer shrinks from the opening portion toward the bottom portion of the insulator, the resin layer can shrink without getting snagged on the inner periphery of the insulator.

摘要： An ignition coil for supplying a high voltage to a spark plug is mainly composed of a cylindrical casing, an outer coil wound around an outer spool and an inner coil wound around an inner spool. The outer coil wound around the outer spool and the inner coil wound around the inner spool are coaxially disposed in the cylindrical casing. Spaces in the cylindrical casing including a first space between the inner coil and the outer spool and a second space between the outer coil and the cylindrical casing are filled with insulating resin. After the resin is supplied into the cylindrical casing, the coils are inserted into the casing containing the resin therein. Accordingly, the resin can be quickly supplied from a wide opening, and the resin can enter into spaces between coils even these spaces are small.

摘要： An ignition coil is equipped with a sparkplug of an engine. The ignition coil includes a coil portion, a tower portion, and a plug cap. The coil portion includes a coil case accommodating a primary and secondary coils being coaxial with each other. The coil portion has an end connected with the plug cap via the tower portion. The plug cap is press-fitted with the sparkplug. The coil case has an outer periphery from which a flange portion projects radially outward in a flange-projecting direction. The tower cylinder portion has a tower axis substantially in parallel with a coil axis of the primary and secondary coils. The tower axis is offset from the coil axis in a tower-offset direction. The tower-offset direction is substantially the same as the flange-projecting direction.

摘要： A spark plug for an internal combustion engine is provided which is equipped with a tip protrusion disposed on a top of a hollow cylindrical housing of the spark plug. The spark plug also includes a center electrode retained in a porcelain insulator disposed inside the housing and a ground electrode is joined to the housing so as to form a spark gap. The tip protrusion serves to direct a flow of gas to be ignited by a spark produced in the spark gap and is shaped to have a radial width extending in a radial direction of the housing and a circumferential width extending in a circumferential direction of the cylindrical housing. The radial width is greater than the circumferential width. This enhances the efficiency in guiding the flow of gas toward the spark gap.
