摘要

A new type driven valve system for combustion engines has been presented, in which a cam is made of permanent magnet, and a roller rocker arm is made of cylindrical permanent magnet. In this system, an attractive force between the cam and the rocker arm due to the magnetic force suppresses jumps and bounces. This makes the friction in the driven valve system decrease. Hence, the resisting torque is decreased by use of this system. This implies that the energy loss decreases. In addition, since the attractive force suppresses the bounce phenomenon, noise due to the bounce is also suppressed in the present system. The analysis for obtaining the critical speed has been presented, and to validate the theoretical results, experimental test has been carried out. In order to have high-energy efficiency, an electric drive valve phase control system is presented. The valve phase control is carried out for the proposed driven valve system by using our control system.
