Abstract
A lubrication system for an internal combustion engine is described that includes a scraper ring with an oil collector located immediately beneath an upper piston ring on a reciprocating piston. The scraper ring serves to deposit oil onto the inner surface of the upper cylinder liner near the combustion chamber in reaction to the decelerating movement of the piston as the piston approaches TDC. The oil scraper collects oil in a collection groove as the piston travels along the lower portion of the cylinder and carries inertia onto the cylinder liner.
