Abstract
An internal combustion engine includes at least one valve flap mounted for swinging movement in the intake duct upstream in the cylinder intake valve. The flap is magnetically attracted to a closed position when an electromagnetic is activated, in order to effect a delayed charging of the cylinder. When the electromagnet is fully or partially deactivated, a pressure differential acting across the flap swings the flap open.
