ABSTRACT:
A cylinder block has a cylinder block body and a cylinder liner block mounted by casting in the cylinder block body. The cylinder liner block is formed from a material having a rigidity larger than that of the cylinder block body, and the cylinder liner block comprises a liner section mounted by casting in position in a cylinder barrel portion of the cylinder block body, and a reinforcing wall section mounted by casting in position in a bearing wall of a crank case portion of the cylinder block body. Thus, it is possible to increase the wear resistance of cylinders in the cylinder block, as well as to provide an increase in performance by reductions in vibration and noise of the engine including the cylinder block, and to provide reductions in size, weight and cost of the cylinder block by a reduction in thickness of the bearing walls.
