摘要： 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.

摘要： An electromagnetically driven valve includes: a valve reciprocating to and fro along a direction in which the valve shaft extends; a disk connected to the valve; a first electromagnet including a first coil; a torsion bar, which is a first elastic member; and an ECU which controls the electromagnet force of the first electromagnet. This ECU controls electrical current so as, when weakening the electromagnetic force of the first electromagnet and separating the disk from the first electromagnet, to reduce the electrical current which flows in the first coil towards zero, after having temporarily increased it from a first holding current to a second holding current which is larger than the first holding current, and then, after the disk has separated from the first electromagnet, so as to flow a braking current for adjusting the speed of the disk.
