<p>A cylinder head for an internal combustion engine, having at least two inlet valves 20 associated with the or each combustion chamber, the inlet valves being supported in the cylinder head with their axes spaced from one another in a first direction, at least two exhaust valves 22 with their axes of reciprocation also spaced from one another in the first direction, and where the axes of reciprocation of the inlet valves lie in a first plane and the axes of reciprocation of the exhaust valves lie in a second plane wherein the two planes are inclined to each other and intersect in the cylinder space. At least two receiving formations for operating elements (such as a spark plug 38 and fuel injector 40), the receiving formations opening into the combustion chamber portion in a central region bounded by the heads of the valves, wherein the receiving formations are inclined to one another so as to diverge generally in the first direction as they extend away from the combustion chamber portion.</p> |
