Abstract
An injection system includes a plurality of actuators. Each of the actuators is configured to move one or more portions of a center body of the fuel injector. The system also includes a controller configured to control each of the plurality of actuators individually to change a flow rate or a direction of output of a mixture of fuel and air from an output of the center body of the fuel injector.
Claims18
A fuel injector control system, comprising:
- a plurality of actuators, each actuator being configured to move one or more portions of a center body of the fuel injector;
- and
- a controller configured to control each of the plurality of actuators individually to change a flow rate or a direction of output of a mixture of fuel and air from an outlet of the center body of the fuel injector.
An adjustable fuel injector, comprising:
- a center body having a tube-like shape with an opening at an upper portion and at a lower portion that is at an opposite end from the upper portion along a length of the center body, the center body configured to mix fuel and air, the fuel and the air being input at the upper portion, and to funnel a mixture of the fuel and the air through an outlet at the lower portion;
- an outer body having a tube-like shape, the outer body encircling the center body and air being input between the outer body and the center body at the upper portion;
- and
- a plurality of actuators controlled by a controller, each of the plurality of actuators being configured to move a different portion of the center body.
1 more element
