ABSTRACT:
An electromagnetically-driven valve includes intake valves that are provided in a gasoline engine and that are arranged side by side; a valve plate that connects the intake valves to each other, wherein driving force that is generated by electromagnetic force is transferred to the valve plate; and a changing mechanism that is fitted to the valve plate. The changing mechanism changes the valve drive state between the two-valve drive state, in which both of the intake valves are driven, and the one-valve drive state, in which one of the intake valves is driven and the other intake valve is stopped.
