A poppet covered orifice fuel injector nozzle for use in a direct injection type diesel engine has a spray tip with a spring biased poppet valve journaled for reciprocable movement therein, the lower reduced diameter free end of the spray tip and the head of the poppet valve having opposed frusto-conical valve seat surfaces with a differential angle of about 2.degree. so that seating engagement occurs at the outer peripheral edges thereof. The poppet valve has a fuel supply passage extending through the stem thereof for flow communication with a plurality of circumferentially spaced apart radial orifices that are inclined and located so as to discharge fuel parallel to and directly across the valve seat surface of the poppet valve.
