Abstract

L'invention porte sur un moteur à taux de compression variable comprenant un bloc-cylindres définissant au moins un cylindre de combustion pour accueillir un piston de combustion, et comprenant au moins un dispositif de guidage du piston de combustion nécessitant une platine de synchronisation (41) positionnée dans une ouverture du bloc-cylindres et solidaire de ce dernier. Le moteur comprend un assemblage multifonctionnel (200) incluant : • Une bride de fermeture (210) fixée au bloc-cylindres, pour fermer ladite ouverture ; • La platine de synchronisation (41), fixée sur une face interne (202) de la bride (210), la rigidité de l'assemblage (200) étant assurée par la bride (210).A variable compression ratio engine comprising a cylinder block defining at least one combustion cylinder to accommodate a combustion piston, and including at least one combustion piston guide device requiring a timing plate (41 ) positioned in an opening of the cylinder block and integral with the latter. The engine comprises a multifunctional assembly (200) including: • A closing flange (210) fixed to the cylinder block, to close said opening; • The synchronization plate (41), fixed to an internal face (202) of the flange (210), the rigidity of the assembly (200) being ensured by the flange (210).
