Title
(EN) PISTON ENGINE AND CYLINDER LINER
(FR) MOTEUR À PISTON ET CHEMISE DE CYLINDRE
Abstract
(EN) The piston engine comprises an engine block (3), at least one cylinder liner (2) that is arranged partly inside the engine block (3), a cylinder head (4) for closing the upper end of the cylinder liner (2), and a cooling jacket (10) that is arranged around the cylinder liner (2) and delimits together with the cylinder liner (2) a cooling channel (12). Each cylinder (1) of the engine is provided with only one cooling channel (12) for cooling the cylinder liner (2), and the whole cooling channel (12) is arranged above the engine block (3). The invention also concerns a cylinder liner (2).
(FR) La présente invention concerne un moteur à piston comprenant un bloc-moteur (3), au moins une chemise de cylindre (2) disposée partiellement à l'intérieur du bloc-moteur (3), une culasse (4) destinée à fermer l'extrémité supérieure de la chemise de cylindre (2), et une enveloppe de refroidissement (10) agencée autour de la chemise de cylindre (2) et délimitant, conjointement avec la chemise de cylindre (2), un canal de refroidissement (12). Selon l'invention, chaque cylindre (1) du moteur n'est équipé que d'un seul canal de refroidissement (12) permettant de refroidir la chemise de cylindre (2), et la totalité du canal de refroidissement (12) est agencée au-dessus du bloc-moteur (3). L'invention concerne également une chemise de cylindre (2).
