Abstract (en)
[origin: CN109779802A] The invention relates to a fuel nozzle and a fuel injection method for a large diesel engine and the large diesel engine. The fuel nozzle is provided with a nozzle head (3), a fuel pipe (4), a valve body (6) and a valve seat (11). Wherein the nozzle head (3) has at least one nozzle opening (30) through which fuel can be introduced into the combustion chamber (50); Fuel energy is introduced into the pressure chamber (5) through the fuel pipe (4); The valve body (6) is loaded with a spring (12), and the valve body (6) comprises a valve piston (61) and a nozzle needle valve (62); The valve seat (11) is designed to cooperate with the nozzle needle valve (62) such that, in the open state, the flow connection between the pressure chamber (5) and the nozzle head (3) is opened by the stroke of thevalve body (6), and in the closed state, the nozzle needle valve (62) cooperates with the valve seat (11) in a sealed manner such that the flow connection between the pressure chamber (5) and the nozzle head (3) is closed.
