Giant magnetostrictive material is a kind of excellent engineering material for its large magnetostriction, fast response speed and high energy density. And giant magnetostrictive injector which employs giant magnetostrictive material driving an electronic controlled injector may be one new promising injector. With more adjustable injection rate, giant magnetostrictive injector can promote energy utilization and reduce pollution emission. This paper provides a detailed overview of the research status of the giant magnetostrictive injector. Some important background information as the properties of giant magnetostrictive material, designing methods of giant magnetostrictive actuator and working circumstances of an electronic controlled injector are introduced firstly. Then the structure design, physical model, numerical simulation and power driver design for the giant magnetostrictive injector are reviewed especially. The summaries may support much useful information for the researchers of giant magnetostrictive injector. Furthermore, some general techniques like bias field utilizing skill, fast driving and simple modeling methods etc. are available to more research fields beyond the limitations of giant magnetostrictive injector.
