description The utility model relates to an internal-combustion engine piston whose surface is provided with two axial grooves. An oil ring is installed in one groove. An air ring whose two or three slots are mutually staggered is arranged in the other groove. The air ring is in a labyrinth type sealing structure. The utility model has the advantages of good sealing performance, engine oil consumption reducing and the service life of a piston and a cylinder increasing.
