Abstract

A cylinder head has four valves and an injection valve arranged in the center thereof for an internal-combustion engine particularly for a diesel engine. The cylinder head includes a closed runner which is arranged concentrically with respect to an axis of the injection valve and which connects a compression bottom with a top side of the cylinder head. Coolant bores extend in direct proximity to inlet and outlet ports from a circumference of the cylinder head to an interior water space of the cylinder head.
