    Abstract: An internal combustion engine for use with hydrogen fuel, the engine having at least one cylinder assembly which includes a combustion chamber having 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. The fuel injector is oriented such that the injector longitudinal axis extends at a first angle; and the fuel flow director is configured to direct fuel flow into the combustion chamber at a second angle, different to the first angle.

    Abstract: An internal combustion engine for use with hydrogen fuel includes at least one cylinder assembly including a combustion chamber, a cylinder, a cylinder head, and a reciprocating piston assembly. Two inlet ports within the cylinder head are selectively closable by a corresponding inlet valve, and at least one outlet port in the head is selectively closable by a corresponding outlet valve. At least one spark plug is mounted to the cylinder head, and the cylinder head comprises a first face and a second face inclined relative to one another and meeting at an apex. The two inlet ports are located within the first face and outlet port is located within the second face. Each inlet port is configured to generate a tumbling motion of the fuel air mixture prior to ignition. The cylinder head is secured by six fasteners, such as six bolts to an engine block defining the cylinder.

    Abstract: An internal combustion engine for use with hydrogen fuel includes a cylinder assembly having a combustion chamber with a cylinder, a cylinder head, and a piston. Two inlet ports are disposed within the cylinder head, the inlet ports being closable by an inlet valve, and an outlet port within the cylinder head being selectively closable by an outlet valve. At least one spark plug is mounted to the cylinder head, and piston assembly having the piston and a crankshaft. A line passes through a center of one of the inlet ports and a center of a corresponding outlet port, with the line arranged at a non-zero angle to an axis of rotation of the crankshaft and with the line at a non-right angle to the axis of rotation. The cylinder head is secured by six fasteners, such as six bolts to an engine block defining the cylinder.

    Abstract: An intake assembly for an internal combustion engine, includes an intake manifold including a first plenum and a plurality of intake runners, the first plenum including an air supply inlet, the intake runners configured to be couplable to a cylinder head of the engine for supplying an air-fuel mixture thereto, the intake manifold configured such that, in use, air is supplied from the air supply inlet to the intake runners via the first plenum; a plurality of fuel injectors, each arranged to inject a fuel into one of the intake runners; and a fuel rail coupled to the plurality of fuel injectors, the fuel rail including a fuel supply inlet, and configured to supply fuel from the fuel supply inlet to the plurality of fuel injectors, in use. The fuel rail is mounted to the first plenum.
