ABSTRACT:
A cylinder head for an air-compressing, self-igniting injection internal combustion engine is disclosed. The cylinder head comprises a substantially plate-shaped cylinder head bottom with adjoining walls of gas exchange ducts and of a secondary combustion chamber separated from each other on the coolant side and exhibiting on the combustion chamber side sealing seats for valves, arranged approximately in a common plane, in the orifices of the gas exchange ducts, and wherein the secondary combustion chamber comprises a combustion port of a cross section smaller as compared with the chamber cross section and the combustion port is oriented approximately centrally toward a relatively wide main web extending between two inlet valves in the cylinder head bottom, characterized in that an outlet valve is arranged in the cylinder head bottom essentially diametrically opposite to an orifice of a single combustion port of the secondary combustion chamber. The improved cylinder head results in a more relatively uniform temperature distribution in the cylinder head bottom.
