A NOZZLE FOR FUEL VALVE FOR INJECTING FUEL INTO THE CYLINDERS OF A LARGE TURBOCHARGED TWO-STROKE COMPRESSION-IGNITED INTERNAL COMBUSTION ENGINE AND AN ENGINE THEREFORE

摘要

A nozzle (40) for a fuel valve (220) for injection of gaseous fuel into a large two-stroke turbocharged compression ignited internal combustion engine with crossheads. The nozzle (40) comprises a nozzle body extending in a main direction and axis X from a base (42) at a proximal end (41) of the nozzle body to a distal end (44) of the nozzle body, the base (42) being configured for attachment to the fuel valve (30), an inlet port (48) opening to the base (42) for receiving fuel from the fuel valve (30), a main bore (50) extending in the main direction X from the inlet port (48) into the nozzle body to a medial position between the base (41) and the distal end (44), a plurality of nozzle holes (45) arranged in the nozzle body near the distal end (44), with each nozzle hole (45) being fluidly connected to the main bore (50) by an individual supply passage (49) extending from the main bore (50) to one of the nozzle holes (45).
