摘要:
An ignition apparatus (10) includes a magnetic circuit comprising a central core (16) and a side core or shield (36), and primary (24) and secondary (30) windings. The shield (36) is allowed to electrically float, thereby reducing the capacitance of the secondary winding (30). A unitary boot (38) surrounds the shield (36) to inhibit arcing, and further includes a seal (46) configured to seal a spark plug well (11) or the like.

An external connection terminal connector as a separate part that mounts the igniter is abolished, and the external connection terminal is integrated with the igniter itself. The igniter has the electronic components mounted on an internal wiring substrate, and the electronic components within the igniter and the external connection terminal are directly connected by wire bonding.

An ignition apparatus (10) includes a central core (16) extending along a main axis (A), and a primary winding (24) disposed radially outwardly thereof. The ignition apparatus (10) further includes a secondary winding (30). The primary winding (24) has a greater axial length than the secondary winding (30), this additional axial length being implemented on the low-voltage axial end (42) of the ignition apparatus, relative to the main axis. The extended primary winding provides an increased leakage inductance spike, which may be used by an ion sense system to (i) obtain increased bias voltages, and, (ii) increase the effective turns ratio, thereby reducing the amount of wire required for the secondary winding.

An ignition coil 100 includes a coil section 10―which in turn includes a coil case 15, a primary coil 12 and a secondary coil 14 accommodated within the coil case 15, and an insulating molded layer 16 filling the coil case 15―and a coil core C including a center core section 20 and a yoke section 30. The ignition coil 100 is mounted on an engine body EB such that the coil core C is insulated from the engine body EB, by means of a mounting section 70. The mounting section 70, together with an insulating filling section 60 filling at least partially a gap S formed between the coil section 10 and the coil core C, which face each other, is integrally formed of a polymeric material through integral injection molding. That is, the ignition coil 100 is mounted on the engine body EB by means of the mounting section 70, which, together with the insulating filling section 60 filling the gap S formed between the coil section 10 and the coil core C, which face each other, is integrally formed of a polymeric material through integral injection molding. Consequently there is disclosed an ignition coil of excellent durability and reliability that is capable of suppressing occurrence of leakage between a secondary coil and a coil core and suppressing generation of corona discharge across a gap between a coil section and the coil core to thereby suppress erosion of, for example, a coil case, which accommodates the primary and secondary coils, even when the maximum-voltage generation capability of the secondary coil is enhanced as a result of, for example, increase in discharge voltage of a spark plug, and the ignition coil is operated continuously for a long period of time, as well as to provide an ignition unit using the ignition coil.

The invention relates to a stick coil (11) for ignition systems, more particularly a stick coil used as ignition coil for internal combustion engines in automobiles. The invention aims at reducing the interference voltage resulting from ignition processes. The stick coil (11) has a core (14) shaped as an I-type core, a tubular recoil closing plate (15) and a primary connection (18). A first electrically grounded contact element (19) is located in the primary connection (18). The first contact element (19) forms part of a power rail (21), which is electrically connected to the recoil closing plate (15) by means of a resistor element (23) or a plate strip (24) so that the interference voltage produced therein is diverted to ground potential. The inventive stick coil (11) is preferably used in automotive manufacturing.

摘要:
An ignition apparatus is received in a plug hole (43a) which is formed by a cylinder head (41a) and a cylinder head cover (42a) of an internal combustion engine. A side core (18) has a slit between two horizontally extending side wall ends. The side core (18) comprises one selected from a laminated sheet structure comprised of two grain oriented silicon steel sheets, each having a slit between two horizontally extending side wall ends, and the plural slits align at a substantially same position. The slit prevents an one-turn short of a magnetic flux of the side core (18), thereby a predetermined secondary voltage more than an engine requirement secondary voltage is obtained. An ignitor reception portion comprises an independent and individual ignitor reception portion and an independent and individual coil reception portion, and the ignitor reception portion and the coil reception portion are combined.
