Abstract
Methods and systems are provided for a fuel injector. In one example, a system may include an injection nozzle having a venturi shape with an upstream twisted fin arranged in a venturi inlet. The system may further include a downstream twisted fin arranged in a venturi outlet.
Claims20
A system, comprising:
- an injector having a venturi-shaped nozzle, wherein the nozzle comprises a plurality of upstream twisted fins arranged in a venturi inlet of the nozzle, and where a leading edge of an upstream twisted fin of the plurality of upstream twisted fins is perpendicular to a trailing edge of the twisted fin.
An injector, comprising:
- a tip including at least one injection nozzle comprising a venturi throat arranged between a venturi inlet and a venturi outlet, and where the venturi inlet comprises at least one upstream twisted fin and the venturi outlet comprises at least one downstream twisted fin spaced away from the upstream twisted fin;
- and
- an air entrainment system fluidly coupled to an extreme end of the venturi outlet and the venturi throat, and where the air entrainment system is arranged completely outside of the at least one injection nozzle.
A fuel injector, comprising:
- a curved tip comprising a central nozzle arranged along a central axis, a plurality of inner ring nozzles arranged around the central axis via a first diameter, a plurality of middle ring nozzles arranged around the central axis via a second diameter, and a plurality of outer ring nozzles arranged around the central axis via a third diameter, and where each of the pluralities of inner, middle, and outer ring nozzles are angled relative to the central axis.
