1. An internal combustion engine for use with hydrogen fuel, the engine having at least one cylinder assembly, the or each cylinder assembly comprising:
a combustion chamber comprising a cylinder, a cylinder head and a reciprocating piston assembly, the cylinder defining a cylinder longitudinal axis;
a fuel injector for injecting fuel into the combustion chamber, the fuel injector defining an injector longitudinal axis; and
a fuel flow director, wherein the fuel flow director is located in a fuel flow path between an outlet of the fuel injector and the combustion chamber;
wherein the fuel injector is oriented such that the injector longitudinal axis extends at a first angle; and
wherein the fuel flow director is configured to direct fuel flow into the combustion chamber at a second angle, different than the first angle; and
further including a chamber disposed between the outlet of the fuel injector and an outlet aperture of the fuel flow director through which fuel leaves the chamber;
and further wherein the chamber has a volume and the outlet aperture of the fuel flow director has a cross-sectional area, and wherein a ratio of the volume of the chamber to the cross-sectional area of the outlet aperture area is in a range of 16:1 to 21:1.
