Abstract:
1. A cylinder head for an internal combustion engine having a crankshaft extending in a longitudinal direction with respect to the internal combustion engine and at least one cylinder with each cylinder defining a cylinder central axis, the cylinder head having a combustion chamber portion associated with each cylinder, the cylinder head comprising: at least two inlet valves supported in the cylinder head, the inlet valves having inlet valve heads and inlet valve stems extending from the inlet valve heads and defining respective axes of reciprocation that are spaced from one another and are arranged in a first plane that is inclined with respect to the cylinder central axis; at least two exhaust valves supported in the cylinder head, the exhaust valves having exhaust valve heads and exhaust valve stems extending from the exhaust valve heads and defining respective axes of reciprocation that are spaced from one another and are arranged in a second plane that is inclined with respect to the cylinder central axis; at least a first receiving formation and a second receiving formation arranged on the cylinder head, wherein the first and second receiving formations are configured for receiving operating elements and opening into the combustion chamber portion in a central region bounded by the inlet valve heads and the exhaust valve heads, wherein the inlet valve heads and the exhaust valve heads are collectively arranged outwardly of the first and second receiving formations; wherein the first and second receiving formations are inclined in opposite directions relative to the cylinder central axis and define respective first and second planes of inclination, wherein the first and second receiving formations diverge from each other and extend away from the combustion chamber portion, wherein each of the first and second planes of inclination of the first and second receiving formations is parallel to the crankshaft; and wherein the first and second receiving formations are aligned with and spaced from each other in a direction that is transverse with respect to the crankshaft and wherein the first and second receiving formations have respective first and second ends proximate the combustion chamber and arranged adjacent to each other.
