Abstract
The cylinder liner is capable of being tightly adhered to an aluminium block. The cylinder liner is made of cast iron and formed into a cylindrical shape. In the cylinder liner, slender section is provided in a middle portion, and outer diameter of the cylinder liner is gradually made greater toward both end sections from the slender section. A plurality of projected lines are formed on an outer circumferential face of the cylinder liner with regular separations and extended in the axial direction thereof. With this structure, the cylinder liner can securely stay in a cylinder block even if an external force in the axial direction works to the cylinder liner. In the cylinder block of the present invention, a plurality of the cylinder liners are enclosed with casted aluminium.
