    摘要： A cylinder liner for an engine cylinder block. A roughening process is performed only on an upper region of the outer surface of the cylinder liner. This increases adhesiveness with a sprayed layer at the upper region compared to a lower region of the liner outer surface. Therefore, difference in thermal conductance is produced in the axial direction of the cylinder liner. This maintains the wall temperature of the cylinder bore in an appropriate temperature range. Even if adhesiveness at the lower region of the liner outer surface is low, bottleneck-shaped projections are distributed on the liner outer surface. Thus, the bonding strength between the cylinder liner and the sprayed layer and the cylinder liner and the cylinder block via the sprayed layer is sufficient. This maintains the roundness of the cylinder bore and prevents fuel efficiency from being lowered by exhaust gas loss and mechanical loss.

    摘要： The present invention provides a cylinder liner excellent in adhesion and heat conductivity with a cylinder block. The cylinder liner 1 of the present invention is formed from cast iron or steel. The cylinder liner 1 is formed with a thermal sprayed coated film 6 at its outer circumferential surface 3 and top surface 4. As the thermal sprayed material, Al, an Al alloy, Fe, an Fe alloy, Zn, a Zn alloy, Cu, a Cu alloy, etc. is used. The cylinder liner 1 is cast around a cylinder block formed from an aluminum alloy or other light alloy, by insert casting, at its outer circumferential surface 3, top surface 4, and bottom surface 5. The cylinder liner 1 is chamfered at the connecting edges of its top surface 4 and inner circumferential surface 7. The thermal sprayed coated film 6 is preferably formed at the top surface 4 part to extend over the chamfering part.
