Zusammenfassung:	To suppress intrusion of a combustion gas into a gap between an upper end surface of a cylinder liner and a base metal of a cylinder block.SOLUTION: A cylinder block 1 for an engine is casted and fixed to a cylinder base metal A in which a cast-iron cylinder liner 10 having a cylindrical shape includes an aluminum material. The cylinder block 1 for an engine E includes: a surface layer 12b including the aluminum material formed at an upper end surface 10a of the cylinder liner 10; and an alloy layer 12a formed between the upper end surface 10a and the surface layer 12b.SELECTED DRAWING: Figure 1 【課題】シリンダライナの上端面とシリンダブロックの母材との間の隙間への燃焼ガスの侵入を抑制する。【解決手段】円筒状を成す鋳鉄製のシリンダライナ１０がアルミニウム素材を含むシリンダ母材Ａに鋳込み固定されたエンジンのシリンダブロック１において、シリンダライナ１０の上端面１０ａに形成されたアルミニウム素材を含む表面層１２ｂと、上端面１０ａと表面層１２ｂとの間に形成される合金層１２ａとを備えたエンジンＥのシリンダブロック１とした。【選択図】図１
