A method of lubricating a two-cycle internal combustion engine, which is capable of preventing blow-by of an air-fuel mixture in a combustion chamber, is provided for increasing fuel consumption and purifying exhaust gas. Lubrication of a valve portion and a sliding portion of a cylinder bore to a piston is improved so as to enhance maintenance performance and further improve fuel consumption. The method for lubricating a two-cycle internal combustion engine in which a control valve is disposed, in communicating passages for communicating a combustion chamber to a chamber portion adjacent to the combustion chamber, wherein the oil is supplied to bearing portions of the control valve for lubricating the bearing portions, and also the oil permeates through the communicating passages to be supplied to a sliding portion of a cylinder bore to a piston by an injection flow of the fuel or the air-fuel mixture, and lubricates the sliding portion.
