An internal combustion engine for use with hydrogen fuel is provided, the engine having at least one cylinder assembly. 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; at least one spark plug mounted to the cylinder head; and a piston assembly comprising a piston and a crankshaft. 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.
