An ignition coil of an ignition system in an internal combustion engine has a housing, a magnetically active core, a first coil winding connected to a supply voltage, and a second coil winding connected to a high-voltage terminal. At least one electrically conductive component is provided, at least in some areas, with a means for an electrically effective evening out of its surface.

Ignition coil

A device for energy storage and energy transformation is described, in particular an ignition coil of an ignition system of a motor vehicle, having a magnetically active I core, which is surrounded by a first coil former having a winding connected to a supply voltage, and a second coil former having a winding connected to a high-voltage terminal, and having a peripheral core forming a magnetic circuit with the I core and enclosing the system made up of the first and second coil formers. In its circumferential extension, the peripheral core has a recess to accommodate an end area of the I core.

Device for energy storage and energy transformation

An ignition coil for an internal combustion engine, including a magnetically active core, a first coil shell which is used as a support for a first coil winding made of an electrically conductive wire, and a second coil shell which is positioned so as to be concentric to the first coil shell and is used as a support for a second coil winding made of an electrically conductive wire. Situated between the first coil winding and the second coil winding is a shielding layer, which is made of an electrically conductive material and provided with a grounding contact.

An ignition coil includes a connecting device for contacting a spark plug of an internal combustion engine, the connecting device being designed to have a sleeve made of insulating material. The sleeve is able to be connected at a first end section to a high voltage side of the ignition coil, and at a second end section has an accommodation for the spark plug. Furthermore, in the sleeve at least one conductive contact part, touching the spark plug, is situated for the electrical connection of the ignition coil to the spark plug. At the high voltage side of the ignition coil, between it and the spark plug, a plurality of electrically conductive modular components are able to be positioned, which in the installed state are connected in a detachable, electrically conducting manner.
