Abstract :
A general model for fuel injection valves using multilayer electrostrictive materials actuators is established. Based upon finite element approach, the model describes the dynamic behaviors of the multilayer electrostrictive actuators and correlates with dynamics of other lumped-parameter components to form overall system state equations for the fuel injector. Simulations are performed for the system using LiF, RbI, and NaF electrostrictive materials with different number of layers to form the actuators
