Summary: | A fuel rail assembly for direct injection of a gaseous fuel into an internal combustion engine comprises a fuel rail defining a flow passage for receiving gaseous fuel and a delivery injector for directly injecting fuel received from the fuel rail into a combustion chamber of the engine. The delivery injector is arranged having a selectively openable delivery port for delivery of gaseous fuel into the combustion chamber when the delivery port is in an open condition. The fuel rail assembly further comprises a valve operable so as to interrupt the flow of gaseous fuel to the delivery injector for delivery into the combustion chamber. A containment zone is defined between the valve and the delivery port when the delivery port is in a closed condition, whereby the containment zone is selected so as to be a prescribed volume. |
