ABSTRACT:
A cylinder head of an internal-combustion engine has three intake valves on one side of a longitudinal center plane and has two exhaust valves on the other side. The intake valves are arranged in a circumferential direction of a cylinder of the internal-combustion engine, and a first intake valve arranged close to the edge of a combustion chamber is permanently driven by a camshaft by means of a space-saving actuating lever. The other intake valves are connected successively or isochronously according to the requirements. When the load is low, a fuel-saying load movement is achieved by the tangential inflow through the first intake valve, while, when the load requirements are higher, an optimized mixture flow rate is possible via the connected valves.
