ABSTRACT:
An internal combustion engine has an oblong piston mounted to reciprocate within an oblong cylinder. The piston is elongated in a direction parallel to the axis of the crankshaft and is provided with piston rings which have sliding contact with the surface of the oblong cylinder. Each piston ring is split and is formed of at least two segments. Gaps may be provided between adjacent ends of the segments and stationary pins fixed on the piston may be received in these gaps. The gaps on one piston ring are misaligned with respect to the gaps on another piston ring.
