A cylinder for an internal combustion engine may include a metallic cylinder body and an amorphous diamond-like hard carbon film disposed on an internal peripheral surface of the cylinder body. The amorphous diamond-like carbon film may include a roughness ranging from Rz 0.5 &#x3bc;m to Rz 4.0 &#x3bc;m.

Cylinder for application on an internal combustion engine

An oil-control ring for an internal combustion engine, to be mounted between the sidewalls of a respective groove of a piston has two ring segments and an annular expander disposed between the two ring segments and presenting a support body defining a seating plane for each ring segment. The ring has at least one expander portion axially projecting from the support body of the expander, beyond at least one of the seating planes of a ring segment, and at least one superficial irregularity provided in at least one of the ring segments and which is dimensioned to be contained in the thickness of the respective ring segment and to interfere with at least one expander portion, in order to rotatively lock the ring segment in relation to the expander.
