Title (EN) CYLINDER HEAD, INTERNAL COMBUSTION ENGINE, AND METHOD FOR MANUFACTURING CYLINDER HEAD
(FR) CULASSE, MOTEUR À COMBUSTION INTERNE ET PROCÉDÉ DE FABRICATION DE CULASSE
(JA) シリンダヘッド、内燃機関およびシリンダヘッドの製造方法
Abstract:
(EN) A cylinder head (1) according to an embodiment of the present invention is provided with: a cylinder head body (10) having an intake port (11) and an exhaust port (12), the cylinder head body being formed of an aluminum alloy; and a valve seat formed of an iron-based alloy and resistance-welded to a downstream end portion of the intake port (11). The valve seat (20) has at least one groove (21), which extends in the circumferential direction of the valve seat (20), on a portion contacting the cylinder head body (10).
(FR) Culasse (1) qui, selon un mode de réalisation de la présente invention, est pourvue : d'un corps (10) de culasse ayant un orifice d'admission (11) et un orifice d'échappement (12), le corps de culasse étant formé d'un alliage d'aluminium ; et d'un siège de clapet formé d'un alliage à base de fer et soudé par résistance à une partie d'extrémité aval de l'orifice d'admission (11). Le siège (20) de clapet comporte au moins une rainure (21) qui s'étend dans la direction circonférentielle du siège (20) de clapet, sur une partie en contact avec le corps (10) de culasse.
(JA) 本発明の実施形態によるシリンダヘッド(1)は、吸気ポート(11)および排気ポート(12)を有するシリンダヘッド本体(10)であって、アルミニウム合金から形成されたシリンダヘッド本体(10)と、鉄系合金から形成されたバルブシート(20)であって、吸気ポート(11)の下流端部に抵抗溶接されたバルブシート(20)とを備える。バルブシート(20)は、シリンダヘッド本体(10)に接触する部分に、バルブシート(20)の周方向に延びる少なくとも1本の溝(21)を有する。
