ABSTRACT:
A reciprocating piston internal combustion engine, each cylinder of which is provided at the connection point of light metal cylinder head and cylinder sleeve with a sealing element. On that surface which is directed toward the combustion chamber, the sealing element is provided with a heat insulating layer. This heat insulating layer serves for thermal insulation of the sealing surfaces of the light metal cylinder head and the cylinder sleeve in order to reduce thermal stresses and radial relative movements resulting from non-uniform thermal expansion characteristics. The end face inner surface of the cylinder sleeve is preferably also thermally insulated.
