Abstract RU 2677437 C1

FIELD: engines and pumps.

SUBSTANCE: nozzle (40) of fuel valve (30) is proposed for injecting gaseous fuel into a large two-stroke internal combustion engine with turbocharging with compression ignition with cross-arms. Nozzle (40) includes a nozzle body extending in the main direction and an X axis extending from base (42) at proximal end (41) of the nozzle body to distal end (44) of the nozzle body, while base (42) is adapted to be fixed to fuel valve (30). Inlet (48) opens toward base (42) to receive fuel from fuel valve (30). Main opening (50) extends in the main direction X from inlet opening (48) inside the nozzle body to a plurality of nozzle holes (45) located in the nozzle body near distal end (44), each nozzle opening (45) is hydraulically connected to main opening (50) by means of separate feed channel (49) extending from main opening (50) to one of nozzles (45).

EFFECT: invention can be used in fuel injection systems of internal combustion engines.
