ABSTRACT:
Cylinder head of an internal combustion engine with more than two valves in overhead arrangement for each cylinder, which are actuated via rocker arms, each rocker arm being individually supported on the cylinder head by means of a bridge. A compact design is achieved by providing a valve bridge for actuation of every two valves of identical function, which valve bridge is attached to the bridge. At least one of the two rocker arms per cylinder acts on a valve bridge supported by the bridge, the pivots of the rocker arms having different distances from the center plane of the cylinder.
