ABSTRACT:
An engine of reciprocating piston type includes a cylinder block which defines one or more cylinders and connected to which is a cylinder head closing the cylinders. Each cylinder reciprocably receives a respective piston and is defined by a respective cylinder barrel which is integral with the remainder of the cylinder block only at one or both ends. The remainder of the length of the cylinder barrel is spaced from the remainder of the cylinder block in the radial direction by a gap which constitutes a cooling passage. The wall of the cylinder barrel affords a plurality of circumferentially spaced ribs extending in the longitudinal direction of the cylinder lining over at least a proportion of its length.
