A new type driven valve system for combustion engines has been presented, in which the cam is made of permanent magnet and the roller rocker arm which is made of cylindrical permanent magnet. In this system, bounce phenomena is suppressed, and so resisting torque of the cam shaft is significantly small in comparison with the previous engines This implies that the control torque is small when controlling valve timing. In order to control the valve timing, this paper proposes new type valve timing mechanism that consists of planetary gear system and the ultrasonic motor. The control method for the valve timing is also presented. To validate the present system and the control method, experimental tests have been carried out for the model of the magnetic engine valve system with valve timing mechanism.
