A fuel injector for injecting gaseous fuels into a combustion chamber, comprising an injection nozzle including a nozzle cap, and an outward opening injection needle. The injection nozzle has 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. The outward opening injection needle is slidably received in the injection nozzle and is engageable with the valve seat to control a flow of gaseous fuel into a sac volume of the fuel injector. The nozzle cap is received over the tip region to define the sac volume, and is 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.

Injector for gaseous fuel

A nozzle assembly includes a body, a valve member, and a clamp member maintaining a flow director member against the body. The flow director member is sandwiched between the peripheral wall and the clamp member, and is provided with an outlet path including two distinct guidance channels extending from an upstream end and a common downstream end where is a spray hole. The outlet path creates impingement of the two flow streams flowing in the two channels before entering the spray hole.

Injector

An arrangement for supplying high pressure fuel to a plurality of fuel injectors includes a housing defining a fuel chamber. The chamber is provided with a flow inlet from a high pressure fuel source and forms a first portion of flow path of the fuel, the chamber being fluidly connected to a conduit providing a second portion of flow path. The conduit has a plurality of outlets adapted to provide flow of high pressure fuel from the chamber via the conduit to a corresponding plurality of injectors via respective first outlet flow conduits. The second portion of flow path is substantially narrower than the first flow path, and includes a pressure sensor located in or adjacent to the conduit.
