IPC: F02F3/00
Filed: 1990-03-29
Abstract: PURPOSE:To supply lubricating oil to a rib so as to prevent any generation of scarfing and cylinder noise by providing a polishing portion having a depth of several tens microns in the vicinity of the rib disposed along the axial direction of a cylinder, and forming a pressure-feed hole for the lubricating oil in the lower portion and inside of the polishing portion. CONSTITUTION:A cylinder 1 of a two-stroke engine comprises an exhaust port 2 and a scavenging port 3. In order to enlarge a lateral width, the exhaust port 2 is provided in the center thereof with a rib 4 for dividing the exhaust port 2 into right and left parts. Because of large thermal expansion due to exposure to exhaust heat, a polishing portion 5 is disposed in the vicinity of the rib 4, which is polished to a depth of several tens microns. A pressure-feed hole 6 for feeding lubricating oil little by little under pressure by means of an oil pump is opened to a wall surface of the cylinder 1 in the lower portion of the rib 4. The lower end of the polishing portion 5 extends down to a position to be connected to the pressure-feed hole 6. Accordingly, the lubricating oil is fed from the pressure-feed hole 6 to lubricate the polishing portion 5 of the rib 4. Therefore, any generation of scarfing can be prevented despite a small polishing margin of the polishing portion 5 of the rib 4, and further, any generation of noise of the cylinder can be prevented.
