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 piston for an internal combustion engine comprises a skirt defining an inner space of the piston and having a skirt bottom; and a target arranged under the skirt bottom to engage with a passage detector arranged in the engine. The target is supported by a holding body held at least partially inside the inner space of the piston. The present disclosure likewise relates to an engine comprising such a piston.

Abstract: A variable compression ratio engine comprises a stationary engine block in which movable members interact to enable a piston to translate in a combustion cylinder of the engine block, defining a stroke of the combustion piston The engine further comprises a self-contained device for adjusting the position of the top dead center of the combustion piston, the self-contained device being connected to or built into at least one of the movable members and having a high-pressure hydraulic chamber to counteract the combustion and inertial forces at the bottom dead center, a low-pressure hydraulic chamber to counteract the inertial forces at the top dead center, at least one calibrated conduit to enable hydraulic fluid to flow between the high- and low-pressure hydraulic chambers, and return means to bring the device back to a nominal position.

Abstract: A rod (1), the length of which is variable, is used for adjusting the compression ratio of an engine. The rod comprises a cylinder rigidly connected to a first end of the rod; a piston that is movable within the cylinder, and is rigidly connected to the second end of the rod, and defines, in the cylinder, a first hydraulic chamber referred to as the “high-pressure” hydraulic chamber, capable of transmitting compression forces, and a second hydraulic chamber referred to as the “low-pressure” hydraulic chamber, capable of transmitting tensile forces; at least one conduit calibrated to enable fluid to flow between the low-pressure chamber and the high-pressure chamber; and return means to bring the rod back to its nominal length, wherein the cross-sections of the low-pressure hydraulic chamber and the high-pressure hydraulic chamber are equal.
