バルブを開けることにより、空気を前記シリンダ
内に吸込み、前記シリンダ内を摺動するピストン
を下降させることによりシリンダ軸を中心とする
空気の旋回流を生成する内燃機関の前記シリンダ
の内壁を形成するシリンダライナにおいて、前記
バルブの開き始めに、該バルブから前記シリンダ
ライナの内壁面に向かう空気をなだらかに該内壁
面に沿うように規制する円弧状切欠を前記内壁面
に形成したことを特徴とするシリンダライナ。 By opening the intake valve at the top of the cylinder forming the cavity, air is sucked into the cylinder, and by lowering the piston sliding inside the cylinder, a swirling flow of air is created around the cylinder axis. In a cylinder liner that forms the inner wall of the cylinder of the internal combustion engine to be generated, an arcuate notch that restricts air flowing from the valve toward the inner wall surface of the cylinder liner so as to gently follow the inner wall surface when the valve begins to open. A cylinder liner characterized in that: is formed on the inner wall surface.
