Title (EN) PISTON WITH ASYMMETRIC UPPER COMBUSTION SURFACE AND METHOD OF MANUFACTURE THEREOF
(FR) PISTON À SURFACE DE COMBUSTION SUPÉRIEURE ASYMÉTRIQUE ET SON PROCÉDÉ DE FABRICATION
Abstract: front page image
(EN) A galleryless piston and method of construction provide a piston body forged from a single piece of material having an upper combustion surface extending around a longitudinal center axis along which the piston reciprocates for exposure to a combustion chamber of an internal combustion engine. The upper combustion surface has an asymmetric geometry relative to a center plane extending along the central longitudinal axis in generally perpendicular relation to a pin bore axis.
(FR) L'invention concerne un piston sans galerie et un procédé de construction permettant de procurer un corps de piston forgé à partir d'une pièce unique de matériau ayant une surface de combustion supérieure s'étendant autour d'un axe central longitudinal le long duquel le piston effectue un va-et-vient pour l'exposition à une chambre de combustion d'un moteur à combustion interne. La surface de combustion supérieure a une géométrie asymétrique par rapport à un plan central s'étendant le long de l'axe longitudinal central selon une relation globalement perpendiculaire à un axe d'alésage de broche.
