Abstract
The present invention relates to an internal-combustion engine comprising at least one cylinder () in which a piston () slides between a top dead center (TDC) and a bottom dead center (BDC) under the action of a connecting rod () of axis XX and a crankshaft () controlling the displacement of the piston under the effect of an articulated linking system () allowing variation of the engine displacement and/or compression ratio. The articulated linking system comprises a shift lever () mounted to pivot around an articulation axle () and is displaceable in translation in at least one direction by displacement control means (V). The shift lever comprises a porthole () within which the axle is housed and is connected by one () of its ends to the connecting rod and by the other () end to a link () connected to the crankshaft. Shift lever () comprises a slider () carrying articulation axle () and cooperating with opening () of the lever.
