Liquid fuel injection nozzle, for internal combustion engines, comprising the combination of (a): a body with a cylindrical cavity at its end; a conduit for passing the fuel into the cavity; an annular seat between the conduit and the cavity, and a bypass port from the cavity, to the discharge end of the body; and (b): a plug composed of a rod with a head having a part cooperating with the seat, and a narrow cylindrical region for occluding the open end of the body cavity when the plug is closed; all arranged so that the initial separation of the plug from its seat allows fuel to pass into the combustion chamber through the bypass port, and, as the plug continues to separate, fuel can also pass through the then-open end of the cavity.
