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.
