Abstract
A nozzle for a fuel injector is disclosed. The nozzle may have an internal axial nozzle bore. The nozzle may also have at least one orifice passing from the nozzle bore radially outward through a wall of the nozzle at a tip end. Further, the nozzle may have a sac volume formed in the tip end and defined by a bore radius and a tip radius. The bore radius may be generally perpendicular to the central bore. The tip radius may be generally parallel to the central bore. The tip radius may be less than the bore radius.
