Oil Flow in Piston Oil Ring Groove 2014-01-1670

The oil flow in the oil ring groove was observed in order to improve the oil ejection efficiency in the oil ring groove. The oil flow was visualized with a clear head piston using fluorescing agent and particles under motoring condition. The influences of oil ring specification on the direction and the velocity of the oil flow were evaluated. The velocity of the oil ring with oil vent holes was faster than that of the oil ring without oil vent holes. In the case of the oil ring with vent holes, the reverse flow of the oil toward the front side was observed in the back clearance. Therefore, oil vent holes can change the oil flow and improve the oil ejection efficiency in the oil ring groove.
