Abstract
A cylinder head with a plurality of cylinder portions for a multi-cylinder internal combustion engine has, in each cylinder portion, a central bore to receive an injection nozzle or spark plug. Also, gas changing channels extend from the deck face facing the cylinder block and emerge from side faces. The valve guide bores are directed towards the ends of the gas changing channels in the deck face. Recesses, for hydraulic cup tappets, are arranged co-axially relative to the valve guide bores. Bearing cradles are present for at least one camshaft. Further, the cylinder head, along the cylinder portions, has an extending cast longitudinal oil channel which supplies oil to the hydraulic cup tappets and, optionally, to the camshaft bearing regions. The longitudinal oil channel, with annular branching channels, enclose each of the bores for the injection nozzle or spark plug.
