Beschreibung
Zusammenfassung:	To propose a fuel injection nozzle for a large diesel engine.SOLUTION: A fuel injection nozzle includes: a nozzle head (3) having at least one nozzle hole (30); a fuel pipe (4) which may inject a fuel into a pressure chamber (5); a valve element having a valve piston (61) and a nozzle needle (62); and a valve seat (11) which is designed to cooperate with the nozzle needle (62). The fuel injection nozzle is provided with an upper chamber (9), a lower chamber (10), a first supply pipe (21), a first discharge pipe (31), a second supply pipe (22), a second discharge pipe (32), and a first control valve (7) and a second control valve (8). The first control valve (7) and the second control valve (8) alternately operate independently of each other. Further, a fuel injection method and a large diesel engine are proposed.SELECTED DRAWING: Figure 1
