Abstract
A liquid-cooled cylinder head for an internal combustion engine which is provided with inlet and exhaust channels disposed opposite one another in the cylinder head longitudinal direction, with a central chamber and with several inlet bores for the cooling liquid in the cylinder head bottom; two ring-shaped cooling channels are thereby provided surrounding the central chamber and disposed one above the other which are connected with each other by two overflow apertures disposed opposite one another in the cylinder head longitudinal direction so that the cooling liquid is forced to flow through the ring-shaped cooling channels one after the other in the circumferential direction in relation to the central chamber; two bores which are located opposite one another in the cylinder head cross direction in proximity of the cylinder head bottom thereby connect the lower ring-shaped channel with two cooling channels that are located along the longitudinal sides of the cylinder head and are fed by two inlet bores each.
