Title
(EN) METHOD FOR MANUFACTURING CYLINDER HEAD, AND CYLINDER HEAD ROUGH MATERIAL
(FR) PROCÉDÉ DE FABRICATION DE CULASSE, ET MATÉRIAU BRUT DE CULASSE
(JA) シリンダヘッドの製造方法及びシリンダヘッド粗材
Abstract
(EN)
A cylinder head rough material (3) having a shielding curtain portion (16g) projecting in an annular shape from an annular edge portion of an opening portion (16a) of an intake port (16) or an opening portion (17a) of an exhaust port (17) toward a center (C) of the port is manufactured, and a valve seat film (16b) is formed by employing cold spraying to spray metal powder (P) onto an annular valve seat portion (16f) positioned further to the outside of the port than the shielding curtain portion (16g).
(FR)
L'invention concerne la fabrication d'un matériau brut de culasse (3) comprenant une portion de capote de protection (16g) qui se projette dans une forme annulaire à partir d'une portion de bord annulaire d'une portion d'ouverture (16a) d'un orifice d'admission (16) ou d'une portion d'ouverture (17a) d'un orifice d'échappement (17) vers un centre (C) de l'orifice. Un film de siège de soupape (16b) est formé en utilisant une pulvérisation à froid pour pulvériser de la poudre métallique (P) sur une portion de siège de soupape annulaire (16f) positionnée davantage vers l'extérieur de l'orifice que la portion de capote de protection (16g).
(JA)
吸気ポート(16)の開口部(16a)、又は排気ポート(17)の開口部(17a)の環状縁部からポートの中心(C)に向かって環状に突出する遮蔽幕部(16g)を有するシリンダヘッド粗材(3)を製造し、遮蔽幕部(16g)よりもポートに対して外側に位置する環状バルブシート部(16f)に、コールドスプレー法により金属粉末(P)を吹き付けてバルブシート膜(16b)を形成する。
