This paper describes performance of a newly designed double tandem Giant-magnetostrictive actuator (DGMA) for a large capacity marine diesel engine injector. The engine needs high-speed and high injection rate of 1000mm^3/ms controllability. The size of DGMA is 135mm in length and 30mm in diameter. It controlled its max displacement of 105μm within 0.5ms at max input current of 14A. Thus, DGMA shortened opening delay-time of the injector by 0.3ms and obtained the required high injection rate on analyses by Bond Graph Simulation Program.
