A fuel injector includes a needle moveable along a central axis to initiate and terminate an injection event, and a nozzle body that receives the needle. The nozzle body includes a needle seat, a nozzle sac, and a passageway between the needle seat and the nozzle sac. The passageway defines a passageway inner surface. The nozzle sac has a curved, non-spherical profile and defines a sac inner surface that extends away from a distal end of the passageway inner surface.
