Abstract
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.
