A Novel of Hybrid Magnet Engine Valve Actuator using Shorted Turn for Fast Initial Response

摘要：

A variable valve timing (WT) can improve fuel efficiency, reduce CO_2 emission and increase torque output. To achieve VVT in internal combustion engine, new devices such as mechanical, hydraulic, motordriven and electromagnetic actuator have been developed in past years to replace the conventional camshaft valve train system used currently. Among these, the electromagnetic actuator using solenoids is the most advance system to provide the most flexibility to valve timing, but it has critical drawback of high power consumption. This paper presents a novel design of Hybrid Magnet Engine Valve Actuator (HMEVA) using shorted turn. A shorted turn is placed into existing design in order to reduce the inductance of coil and improve the initial response. Dynamic finite element analysis using commercial electromagnetic solver MAXWEL is performed to simulate the improvement of dynamic characteristic of model.
