METHODS AND SYSTEMS FOR A FUEL INJECTOR

Methods and systems are provided for a fuel injector. In one example, a system may include a fuel injector having a half-annular venturi shaped outlet passage arranged between an outlet surface of the fuel injector and a half-cone shaped end portion of a nozzle. The nozzle may further comprise one or more air entraining features working in tandem with the half-annular venturi outlet passage to promote air-fuel mixing.
