成される開口をマスク壁によつて覆うようにした
内燃機関のシリンダヘツドにおいて、給気弁周り
の給気ポート部分を上方に向かうに従つてマスク
壁から離れる方向に湾曲する上方に凸の湾曲形状
に形成すると共に該給気ポート部分に続いて上方
に延びる給気ポート部分を下方に凸の湾曲形状に
形成した内燃機関のシリンダヘツド。 In the cylinder head of an internal combustion engine in which the opening formed between the peripheral edge of the air intake valve located on the exhaust valve side and the valve seat is covered by a mask wall, the air intake port around the air intake valve is opened upward. Therefore, the cylinder head of an internal combustion engine is formed into an upwardly convex curved shape that curves away from the mask wall, and an air intake port portion extending upward following the air intake port portion is formed into a downwardly convex curved shape. .
