Abstract
A liquid-cooled cylinder head for a multicylinder internal combustion engine. The cylinder head has a coolant chamber in which gas exchange passages running in the direction of a transverse engine axis and at least one chamber for a spark plug and/or an injection nozzle are arranged. Also, bolt pipes for distributing the bolt tension forces of the cylinder head bolts are provided, the cylinder head being joinable to a crankcase of the internal combustion engine with interposition of a cylinder head seal. The bolt pipes have ribs formed by thickened configurations of adjacent wall sections of the gas exchange passages in the region of the cylinder head bolt. A high, uniform surface pressure on the cylinder head seal is thereby enabled, even in the regions between the cylinder head bolts, and even when space is restricted.
