Abstract
The present disclosure provides a fuel injector including a magnetostrictive actuator that is capable of precise control of a needle or nozzle valve element. The magnetostrictive actuator is direct-acting on the nozzle valve element, which extends into the magnetostrictive actuator, providing a compact fuel injector configuration that may provide rate-shaping of a fuel injection event.
