とを特徴とする内燃機関のピストン構造。In a piston in which a particulate prevention ring, a first compression ring, a second compression ring, and an oil ring are provided in order from the top, the ring land is formed by an annular groove into which each of the rings is inserted, and the ring land is the first ring land from the top surface of the piston. A piston structure for an internal combustion engine, characterized in that the lands up to the second compression ring are tapered and smoothly connected, but the lands below the second compression ring are formed in a concave manner.
