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

An ignition system for an internal combustion engine is able to operate without malfunctions, even under unfavorable surrounding conditions, in particular intensive attack by spray water. To that end, the ignition system, projecting into a compartment of a cylinder head, is provided with a protective covering in which are formed a connecting duct that is connected to the compartment, and a vent duct leading into the atmosphere. Both ducts are interconnected by a storage of the ignition coil. Water penetrating into the ignition coil is caught in the storage and evaporated in such a way that no malfunctions occur at the ignition coil. The ignition system is preferably used in manufacturing automobiles.
