摘要： An internal combustion engine having a cylinder block made of a light-alloy with a cylinder wall around a cylinder bore including a cylindrical fiber-reinforced portion which is formed of a mixture of an alumina-based fiber and a carbon fiber with a light-alloy matrix. The alumina-based fiber has a fiber volume fraction set in a range of 8 to 20%, and the carbon fiber has a fiber volume fraction set in a range of 0.3 to 15%. The alumina-based fiber contains 25% or less, by weight, of silica, has an average aspect ratio of 20 to 150, and an alpha rate of 2 to 60%. The carbon fiber has an average aspect ratio set in a range of 10 to 100 and a Young's modulus set in a range of 20 to 30 t/mm.sup.2. The piston for the cylinder bore has an iron-plated layer covered by a tin-plated layer. The piston rings for the piston may be of austenitic stainless steel to provide thermal expansion characterics similar to the cylinder wall and may be provided with a nitride or chromium-plated layer.

摘要： 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.

摘要： A cylinder block is produced by subjecting an outer surface of a cylinder sleeve section Sc of cast iron to a shot blast treatment, forming a first intermediate layer 31 of aluminum-based material containing Si, Cu and the like on the cylinder section Sc, and inserting the cylinder sleeve section Sc in a cast-in manner within a cylinder barrel 1.sub.U of aluminum alloy. The electrical-potential difference between the cylinder sleeve section Sc and the cylinder barrel 1.sub.U and the first intermediate layer 31 is decreased by the first intermediate layer 31 to enhance the durability against an electrolytic corrosion and to enhance the deposition by a mutual diffusing action therebetween. In a modification, a second intermediate layer 32 of a Ni-Al based material is formed under the first intermediate layer 31 at a portion of the cylinder sleeve section Sc inserted in a cast-in manner within the cylinder barrel 1.sub.U, whereby the adhesion can be further enhanced.
