Abstract
An ignition system for an internal combustion engine includes a spark plug including a prechamber in which a spark gap is located. A plug cover covers the prechamber and includes an ejection hole, which connects the prechamber to a main combustion chamber of the internal combustion engine. The ignition system for the internal combustion engine is configured to apply a pre-discharge voltage that causes a pre-discharge across the spark gap during an intake stroke of the internal combustion engine.
