Abstract: An ignition coil (10), especially for an internal combustion engine of a motor vehicle, has an internal magnetic core (26) which is concentrically surrounded by a primary spool (18) and a secondary spool (19). The internal magnetic core (26) is made up of strips of sheet metal layered over each other (30, 30a; 30, 30b, 30c), whereby the strips of sheet metal (30, 30a; 30, 30b, 30c) primarily form a rectangular and/or square cross sectional area of the internal magnetic core (26). The invention distinguishes itself in terms of the lower and upper strips of sheet metal forming the boundary of the internal magnetic core (26) which is reduced in width (b), at least in the areas opposite the other strips of sheet metal (30) of the internal magnetic core (26) when viewed laterally. This makes possible a primary spool body (22) and/or secondary spool body (24) with an enlarged corner radius (r) and uniform winding density of the primary spool (18) and/or the secondary spool (19) possible.

Abstract: An ignition coil assembly (10) includes a cylindrical central core (16) having a main axis ("A"), a primary winding (18) outwardly of the central core (16), a secondary winding (30) outwardly of the primary winding (18), and a case having a first tube (34) formed of a material having mica dispersed in a binder. The binder is may be a silicone-based binder, an epoxy-based binder or any other binder configured to adhere to the mica. The overall diameter of the ignition coil assembly (10) can reduced relative to conventional designs since the case thickness can be reduced over known designs.

Abstract: 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.

Abstract: The invention relates to a rod coil (11) for ignition systems, said rod coil being especially used as an ignition coil in internal combustion engines of motor vehicles. The aim of the invention is to produce one such rod coil in such a way that it is permanently functionally reliable. The inventive rod coil (11) comprises a core (14), in its centre, which is embodied as an inner magnetic iron core, and a return tube (18) which is embodied as an outer magnetic iron core and is positioned on a plastic housing (13). A filler (22) is applied between the return tube (18) and the housing (13) in order to avoid partial discharges during the operation of the rod coil (11), in such a way that an intimate continuous structure is formed between the return tube (18) and the housing (13).

Abstract: An object of the present invention is to provide an ignition coil which has a structure to make it possible to connect the ignition coil to a spark plug directly and in which an installation space need not be changed largely when the ignition coil is mounted in a cylinder head, and an internal combustion engine ignition system having the ignition coil.
In the present invention, a protection metal pipe (31) of an ignition coil (9) is formed so that a rear end side portion of a spark plug (11) in the rear of a rear end surface (23b) of a collar portion (23) in a metal shell (19) can be received in the inside of the protection metal pipe (31) from a front end (31b). The ignition coil (9) has a structure in which the ignition coil (9) is directly connected to the spark plug (11). The protection metal pipe (31) of the ignition coil (9) is formed to serve also as a plughole pipe, so that the outer diameter of the protection metal pipe (31) can be enlarged up to the outer diameter of a conventional plughole pipe. As a result, a space for installing a coil body portion (37) can be secured largely in the inside of the protection metal pipe (31), so that the installation space need not be changed largely when the ignition coil is mounted in a cylinder head.
