Injector for gaseous fuel

A fuel injector for injecting gaseous fuels into a combustion chamber, the fuel injector comprising:

• an injection nozzle having a longitudinal injector axis and a tip region that is shaped to define a valve seat that extends about a central outlet opening for gaseous fuel;
• and
• an outward opening injection needle slidably received in the injection nozzle and engageable with the valve seat to control a flow of gaseous fuel into a sac volume of the fuel injector,
• wherein the injection nozzle further includes a nozzle cap having a nozzle cap axis, aligned with the longitudinal injector axis, the nozzle cap being received over the tip region of the nozzle to define the sac volume and being provided with a plurality of openings to enable the flow of gaseous fuel to pass from the sac volume into the combustion chamber when the injection needle is moved away from the valve seat,
• the plurality of openings being comprised of at least;
• a first opening configured to direct a first flow portion of the flow of gaseous fuel into a first zone of the combustion chamber;
• and
• a second set of openings, configured to direct a second flow portion of the flow of gaseous fuel into a second zone of the combustion chamber.
