Abstract

This paper presents a conceptual design and control of a novel Gasoline Direct Injector (GDI) using of giant magnetostricitve material, Terfenol-D, as an actuation component. Electromagnetic and fluid analyses are accomplished to investigate the influence of some parameters such as nozzle length, pressure of input fuel, cone angle of injector´s needle are investigated. Experimental results obtained from fabricated GDI show a good agreement with the numerical results provided by 3D finite element analysis. Furthermore, the fabricated GDI is controlled by fuzzy and PID controllers. It is found that fuel consumption by fuzzy controller is 3.5% less than PID controller.
