Abstract

A light metal cylinder head for internal combustion engines, with a metal plate arranged on the cylinder head bottom. The plate has an annular insert on its outer periphery. The annular insert is arranged on the cylinder head and/or cylinder pipe in such a manner that forces are effective upon the metal plate due to different heat stresses occurring in operation, so that the plate engages against the cylinder head bottom.
