Abstract

A liquid-cooled individual cylinder head for piston internal combustion engines with two inlet valves and two outlet valves arranged respectively adjacent one another, which consists of a cast upper part and of a double-walled bottom between the upper part and the combustion space, which is provided with apertures for the valves and for an injection nozzle or a pre-chamber; the bottom extends over the entire surface of the cylinder head upper part up to the outer boundary thereof while the lower surface of the upper part and both surfaces of the bottom are constructed planar; the two parts of the bottom are supported with respect to one another by wall portions or ribs within an annular zone in the area of the support of the bottom on the cylinder head seal while several cooling medium inlet openings are distributed in the lower wall of the double-walled bottom between the annular zone and an outer boundary.
