Design and Simulation of Hybrid Double Solenoid Valve Actuator

Abstract

This paper proposes a novel hybrid valve actuator (HVA) with permanent magnet (PM) and electromagnet (EM) magnetomotive force (MMF) for variable valve timing camless engine. Traditional double solenoid valve actuator (DSVA) has inherent problem of high power consumption, as armature is at equilibrium position away from electromagnet therefore to move armature to open/close position and for keeping armature latched to EM. Hybrid PM/EM valve actuator is proposed in this study. The finite element analysis is performed with Ansys Maxwell on static characteristics of traditional DSVA and HVA on bases of actuator holding force. The equivalent model of static analysis is introduced into Ansys Simplorer for dynamic analysis. The simulation results depict reduce power consumption and transition time of proposed HDSVA over DSVA.
