ABSTRACT:
A fuel injection nozzle for internal combustion engines comprises a nozzle body (1) and a nozzle needle (5) guided therein. The nozzle body (1) terminates in a nozzle cap (3) in which ejection bores (4) are provided and which forms at the inside a conical valve seat (6) against which the nozzle needle (5) is pressed. The nozzle needle (5) lifts under the pressure of the fuel supplied in a first lifting phase against the force of a spring (8) off the valve seat (6) and bears on a stop (19). This stop (19) is limitedly displaceable in a second lifting phase against the force of a further spring (9). To reduce the hydrocarbon emissions in the exhaust gases of the internal combustion engine and diminish ignition noise, the generated surface (M) of the imaginary cylinder formed in extension of the ejection bore (4) between the inner edge (R) thereof and the surface of the nozzle needle (5) lifted off the valve seat in the first lifting phase is made smaller than the cross-section of the ejection bore (4).
