Abstract: An internal combustion engine comprises a connecting rod and a target arranged on one of the lateral reinforcing walls of a piston or on a foot end of the connecting rod, and a crankcase defining at least one cylinder and having at least one bore opening out under the cylinder. The engine comprises a measuring device arranged in the bore of the crankcase and having a target passage detector, and a connector and at least one cable connecting the passage detector to the connector. The target is arranged opposite the passage detector, when the piston is near a bottom dead center position.

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 telescopic control connecting rod for a variable compression ratio engine, comprises: a small end having, respectively, an eye and a piston at its ends; a big end serving as cylinder body in which the piston defines a first and a second hydraulic chamber, and a third side chamber located between the first and the second hydraulic chambers; the big end comprises two coaxial side bearings configured to establish a pivot link with a fixed part of the engine; a lubrication circuit comprising at least a first duct provided in the big end, connecting an inner space of each side bearing and the third chamber, whatever the length of the connecting rod, and comprising at least one second duct provided in the small end, connecting the third chamber and the eye.
