    Abstract: Apparatuses and methods for fuel injection are disclosed. The apparatus includes an inner sac with one or more primary passages extending therefrom. The one or more primary passages inject fuel therethrough and comprising a first portion, a second portion, and a third portion, where the second portion is disposed between the first portion and the third portion and has a cross-sectional area smaller than that of both the first portion and the third portion. The apparatus also includes one or more secondary passages extending from an outer surface of the apparatus to fluidly couple with the second portion of the one or more primary passages. The one or more secondary passages inject air to form fuel-and-air mixture with the fuel injected from the one or more primary passages.
