Title (EN) CYLINDER LINER, CYLINDER BLOCK, AND METHOD FOR MANUFACTURING CYLINDER LINER
(FR) CHEMISE DE CYLINDRE, BLOC-CYLINDRES, ET PROCÉDÉ DE FABRICATION D’UNE CHEMISE DE CYLINDRE
Abstract:
(EN) A cylinder liner for an engine cylinder block. A roughening process is performed only on an upper region of the outer surface of the cylinder liner. This increases adhesiveness with a sprayed layer at the upper region compared to a lower region of the liner outer surface. Therefore, difference in thermal conductance is produced in the axial direction of the cylinder liner. This maintains the wall temperature of the cylinder bore in an appropriate temperature range. Even if adhesiveness at the lower region of the liner outer surface is low, bottleneck-shaped projections are distributed on the liner outer surface. Thus, the bonding strength between the cylinder liner and the sprayed layer and the cylinder liner and the cylinder block via the sprayed layer is sufficient. This maintains the roundness of the cylinder bore and prevents fuel efficiency from being lowered by exhaust gas loss and mechanical loss.
(FR) La présente invention concerne une chemise de cylindre d’un bloc-cylindres de moteur. Un procédé de grattage est réalisé uniquement sur une région supérieure de la surface externe de la chemise de cylindre. Ceci augmente l’adhésivité avec une couche pulvérisée sur la région supérieure par rapport à une région inférieure de la surface externe de la chemise. Par conséquent, une différence de conductance thermique apparaît dans la direction axiale de la chemise de cylindre. Ceci maintient la température des parois de l’alésage du cylindre dans une plage de température appropriée. Même si l’adhésivité au niveau de la région inférieure de la surface externe de la chemise est faible, les saillies en forme de goulot d’étranglement sont réparties sur la surface externe de la chemise. Par conséquent, la résistance d’adhésion entre la chemise du cylindre et la couche pulvérisée et entre la chemise du cylindre et le bloc-cylindres via la couche pulvérisée est suffisante. Ceci maintient l’arrondi de l’alésage du cylindre et empêche la diminution du rendement du carburant suite à une perte des gaz d’échappement et une perte mécanique.
