摘要： An internal combustion engine for use with hydrogen fuel is provided, the engine having at least one cylinder assembly. The or each cylinder assembly comprises a combustion chamber comprising a cylinder, a cylinder head and a reciprocating piston assembly; two inlet ports within the cylinder head, the inlet ports being selectively closable by a corresponding inlet valve; at least one outlet port within the cylinder head, the at least one outlet port being selectively closable by a corresponding outlet valve; and at least one spark plug mounted to the cylinder head. 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 the or each outlet port are located within the second face. This is such that the or each inlet port is configured to generate a tumbling motion of the fuel air mixture prior to ignition thereof. The cylinder head is secured by six fasteners, such as six bolts to an engine block defining the cylinder.

The engine further comprises a line passing through a centre of one of the inlet ports and a centre of a corresponding at least one outlet port. The line is arranged at a non-zero angle to an axis of rotation of the crankshaft and the line is at a non-right angle to the axis of rotation of the crankshaft. The cylinder head is secured by six fasteners, such as six bolts to an engine block defining the cylinder.

摘要： 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. 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.
