Abstract
In a cylinder lubrication system for a two-stroke engine, a plurality of lubricating oil supply openings () open out in the inner circumferential surface of the cylinder () at a point lower than a top ring () of a piston () located at a bottom dead center. The lubricating oil supply openings are configured to provide a larger amount of lubricating oil in the thrust side and anti-thrust side of the cylinder than in a remaining part of the cylinder. Thereby, the consumption of lubricating oil and the emission of undesired substances can be minimized while providing an optimum lubrication of the sliding part between the piston and the cylinder.
