An assembly for a combustion engine may include a piston and a connecting rod. The piston may include a piston crown, a piston skirt, and respective portions for accommodating a piston pin through which the piston is intended to be supported on the connecting rod. The piston skirt may have a completely closed bottom part and apertures may be provided in the portion for accommodating the piston pin. The apertures may seal against the piston pin to enclose a bottom part of the piston crown as well as the piston crown portion for accommodating the piston pin. The connecting rod may have a fork shape in an end facing the piston.
