Abstract

L'invention concerne un dispositif de réglage pour un moteur à taux de compression variable d'un véhicule automobile, le moteur à taux de compression variable comprenant un bloc-cylindres 10, un carter d'huile 20, une bielle 50 de longueur effective variable, un vilebrequin 30 et un piston 40, le piston 40 étant conçu pour entraîner la bielle 50, la bielle 50 étant elle-même reliée au vilebrequin 30, la bielle 50 étant munie d'un organe mobile 790 dont le déplacement par rapport à la bielle 50 provoque une variation de la longueur effective de la bielle 50, le dispositif de réglage comprenant un élément de guidage 80, un support 90 de l'élément de guidage et un ensemble d'actionnement, l'élément de guidage 80 étant conçu pour coopérer mécaniquement avec l'organe mobile 790 de manière à contraindre le déplacement de l'organe mobile 790 par rapport à la bielle 50, l'ensemble d'actionnement comprenant un moteur d'actionnement 100 et un organe d'actionnement 110 entraîné par le moteur d'actionnement 100, l'organe d'actionnement 100 étant conçu pour déplacer l'élément de guidage 80 par rapport au support 90 de l'élément de guidage, caractérisé en ce que l'organe d'actionnement 110 et le moteur d'actionnement 100 sont agencés à l'intérieur du carter d'huile 20. L'invention concerne encore un moteur à taux de compression variable comprenant un dispositif de réglage tel que décrit ci-dessus.The invention relates to an adjustment device for a variable compression ratio engine of a motor vehicle, the variable compression ratio engine comprising a cylinder block 10, an oil pan 20, a connecting rod 50 of variable effective length. , a crankshaft 30 and a piston 40, the piston 40 being designed to drive the connecting rod 50, the connecting rod 50 itself being connected to the crankshaft 30, the connecting rod 50 being provided with a movable member 790 whose displacement relative to the connecting rod 50 causes a variation in the effective length of connecting rod 50, the adjuster comprising a guide member 80, a support 90 for the guide member and an actuator assembly, the guide member 80 being adapted to mechanically cooperate with the movable member 790 so as to constrain the movement of the movable member 790 relative to the connecting rod 50, the actuating assembly comprising an actuating motor 100 and an actuating member 110 driven by the ac motor actuation 100, the actuator 100 being designed to move the guide member 80 relative to the support 90 of the guide member, characterized in that the actuator 110 and the actuator 100 are arranged inside the oil pan 20. The invention also relates to a variable compression ratio engine comprising an adjustment device as described above.
