Abstract
Methods and systems are provided for a fuel injector. In one example, a system may include forming an annular venturi passage between an outlet surface of the fuel injector and a nozzle. The nozzle may further comprise one or more air entraining features that may work in concert with the annular venturi passage to promote air-fuel mixing.
Claims20
A system, comprising:
- a fuel injector comprising an egg-shaped nozzle, wherein an opening is shaped to admit combustion chamber gases into a hollow interior of the egg-shaped nozzle forming an annular venturi passage between it and an outlet surface of the fuel injector.
A method, comprising:
- adjusting a fuel injection angle of a fuel injector via adjusting an interface between a rod coupled to an actuator and a venturi-shaped nozzle, the fuel injection angle decreased via actuating the rod away from the venturi-shaped nozzle.
A system, comprising:
- an engine having at least one combustion chamber;
- a fuel injector positioned to inject into the at least one combustion chamber, the fuel injector comprising an egg-shaped nozzle having a one or more openings fluidly coupling a hollow interior of the egg-shaped nozzle to the at least one combustion chamber;
- and
- a controller with computer readable-instructions stored on non-transitory memory thereof that when executed enable the controller to:
- press the egg-shaped nozzle against an outlet surface of the fuel injector in a first position;
- and
- move the egg-shaped nozzle away from the outlet surface of the fuel injector in a second position.
