Abstract
The present technology relates generally systems and methods for providing motion amplification and compensation by fluid displacement in fuel injector systems. For example, some embodiments of gaseous fuel injectors include a piezoelectric actuator and a motion transfer system coupled to the piezoelectric actuator. The motion transfer system includes a housing, a first piston having a first effective area disposed in the housing, and a second piston having a second effective area disposed in the housing. The second effective area is less than the first effective area and the first and second pistons define a fluid chamber therebetween. The motion transfer system can amplify actuation of a fuel injector valve.
