ABSTRACT:
A reciprocating internal combustion engine includes at least one wet cylinder sleeve which is inserted into a cylinder crank housing. The upper portin of the sleeve is clamped between a cylinder head and a cylindrical receptacle disposed inside the cylinder crank housing. Coolant flows through a space adjacent said upper portion. A lower portion of the cylinder sleeve is separated from the coolant and extends inside the receptacle. To achieve a favorable temperature pattern over the entire height of the cylinder sleeve, the coolant containing space has a broad cross-section in the upper portion of the cylinder sleeve formed by a constricted wall on the outer periphery of the cylinder sleeve. Furthermore, a closed annular air space is provided between the cylindrical receptacle and the lower portion of the cylinder sleeve.
