Internal combustion engine

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 the 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 to the first angle;
• wherein the first angle is a non-zero angle in relation to the cylinder longitudinal axis, and wherein the second angle is within 30° of the angle of the cylinder longitudinal axis;
• and further wherein the cylinder assembly comprises a sleeve surrounding the fuel injector, the sleeve comprising the fuel flow director, the sleeve having a first end that extends over the fuel injector and a second end that extends beyond an outlet of the fuel injector, the second end comprising the fuel flow director, and wherein the second end of the sleeve defines a chamber between the fuel injector outlet and the fuel flow director.
