Abstract: A crankshaft for a controlled variable compression ratio engine has an axis of rotation defining a longitudinal axis and comprises at least one crank pin, at least one journal connected by a connecting web, and at least one control element able to move translationally along the longitudinal axis in order to cooperate with an actuator of a system for adjusting the length of a connecting rod. The crankshaft is notable in that the control element, positioned at the connecting arm, comprises an annular part coaxial with the crank pin and capable of establishing continuous contact with the actuator of the system for adjusting the length of the connecting rod, regardless of the angular position of the crankshaft. The crankshaft comprises a fluidic control circuit for moving the control element along the longitudinal axis.

Abstract: A bearing guide device of a combustion piston for a variable compression ratio engine. The movement of the combustion piston from a top dead center to a bottom dead center drives the movement of a synchronized roller made up of a cylindrical body and a pinion from a first position to a second position relative to first and second racks. According to the disclosure, the first and/or second racks have a different circular pitch than the pinion so that the flanks of the teeth of the pinion engage with the flanks of the teeth of the first and second racks only when the pinion is in the first or second position.

Abstract: A connecting rod for an internal combustion engine includes a first portion and a second portion respectively associated with a head and a foot. The portions are configured to slide relative to each other along the longitudinal axis of the connecting rod so as to form a variable-length connecting rod. The connecting rod comprises an indexing device of the first and second portions to ensure both of the portions are given a specific relative orientation. The indexing device comprises a first element, which is rigidly connected to the first portion and supported by the head of the connecting rod.

Abstract: A transmission device, particularly for an engine with variable compression rate and/or variable displacement, includes, in a cylinder housing: a combustion piston capable of moving in a combustion cylinder of the engine and secured to a transmission member; a gear engaging with a first rack of the transmission member and providing transmission of the movement between the combustion piston and a crankshaft of the engine; a connecting rod engaging, at a first end, with the gear and, at a second end, with the crankshaft; and a control member engaging with the gear and secured to a control piston. The combustion piston and the transmission member are slidably linked with the cylinder housing in a main direction.

Abstract: A device for compensating for the operating clearances of an engine comprising a transmission device likely to move transversely in an engine block) during an engine cycle includes a pressing device exerting a holding force on the transmission device. The holding force is adjusted to the instantaneous speed of transverse movement of the transmission device in the engine block.
