摘要： Described is a fuel valve (1) for a large turbocharged two-stoke uniflow crosshead internal combustion engine, said fuel valve (1) comprising an elongated fuel valve housing (2) with a rear end (3) and a front end (4), a nozzle (5) with at least one bore (7) opening into at least one nozzle hole (9) having a nozzle hole area, said nozzle (5) being arranged at the front end (4) of said housing (2), a fuel channel (11) extending from the rear end (3) towards the front end (4) and being connected to a source of pressurized fuel, an axially displaceable valve needle (12) having a closed position, in which said axially displaceable valve needle (12) is resting on a valve seat (8) preventing fuel from flowing to the nozzle (5), and an open position in which said axially displaceable needle (12) is lifted from said valve seat (8) thereby exposing a valve needle flow area (13) between said needle (12) and said valve seat (8) allowing fuel to flow through the fuel valve (1) to the nozzle hole (9) via a flow path defined by at least the fuel channel (11), the valve needle flow area (13) and the at least one bore (9) in the nozzle (5). The fuel valve (1) is peculiar in that it comprises a flow restriction (20) in said flow path of the fuel.
Hence, by introducing a flow restriction (20) in the flow path at a different location than the nozzle hole(s) (9) itself the injection flow rate is determined by the injection pressure and the effective open flow area of the flow restriction (20), thereby avoiding high exit velocities into the cylinder at the nozzle hole(s) (9). In this way the fuel may be injected into the combustion chamber (10) of a cylinder of an internal combustion engine at a lower injection velocity and thus facilitating a lower risk of extinction of the flame, while still maintaining a high fuel supply pressure in the fuel injection system. The fuel, such as ammonia may thus be injected with a well-controlled mass rate into the cylinder, that eliminates or at least lowers the risk of extinction of the flame.
