Design and Static Magnetic Analysis of Magnetostrictive (Tb_0.3Dy_0.7Fe_1.95) Fuel Injector with Flexible Piston Hydraulic Displacement Amplification

Abstract:

This paper presents the conceptual design of fuel injector based on giant magnetostrictive material, with displacement amplification mechanism. The permissible emission level EURO norms become stricter in case of fuel injection technology of modern combustion engine. The magnetic circuit of the magnetostrictive fuel injector is analyzed using finite element method. Based on the structure and working principle of our magnetostrictive fuel injector (MFI), the properties of driving magnetic field are researched.
