Abstract
A cylinder head and combustion chamber sealing arrangement that is subdivided into a sealing element in the cylinder liner region (especially for sealing gas) and a sealing element in the cylinder block region. Both sealing elements are made of solid metal. The sealing element for gas sealing, which is disposed in the liner-collar recess, is stressed in a certain range beyond the yield limit of the material by tightening the cylinder head screws. To improve the gas sealing, on the one hand a circumferential groove is provided in the cylinder head opposite the recess in the cylinder liner collar, and on the other hand the recess itself is provided with either a circumferential groove or a circumferential rib. By this means, the liner sealing element is stressed beyond the material yield level in the specific region of its outer and inner perimeters.
