Title
(EN) THERMALLY ENHANCED EXHAUST PORT LINER
(FR) CHEMISE D'ORIFICE D'ÉCHAPPEMENT THERMIQUEMENT AMÉLIORÉE
Abstract
(EN)
An exhaust port liner, which may include a superalloy and may be manufactured by an additive manufacturing process, includes a monolithic structure including an outlet disposed an angle relative to an inlet, and a sidewall defining a cavity to provide enhanced thermal performance in reciprocating internal combustion engines. A cylinder head of an internal combustion engine may include a cylinder head frame, and the exhaust port liner may be disposed proximate the frame inner mounting surface, with an outer surface of the exhaust port liner conforming to an inner mounting surface of the cylinder head frame.
(FR)
La présente invention concerne une chemise d'orifice d'échappement, qui peut comprendre un superalliage et peut être fabriqué selon un procédé de fabrication additive, comprend une structure monolithique comprenant une sortie formant un angle par rapport à une entrée, et une paroi latérale délimitant une cavité pour fournir des performances thermiques améliorées dans des moteurs à pistons à combustion interne. Une culasse d'un moteur à combustion interne peut comprendre un cadre de culasse, et la chemise d'orifice d'échappement peut être disposée à proximité de la surface de montage interne du cadre, une surface externe de la chemise d'orifice d'échappement prenant la forme d'une surface de montage interne du cadre de culasse.
