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.
