    摘要： A piston and internal combustion engine therewith constructed in accordance with the present invention has a piston body with an upper crown having a substantially cylindrical outer surface depending from a top surface along a central axis. At least one annular ring groove extends radially into the outer surface to provide a top land extending from the ring groove to the top surface. A plurality of waves are formed circumferentially about the top land. Each of the waves has a valley extending radially into the outer surface of the top land and extending from the top surface to the ring groove. The waves traverse from the top surface to the ring groove and are configured in substantially non-overlapping relation with one another and in a predetermined orientation relative to at least one of a fuel spray stream, a pin bore axis or a thrust axis of the piston.
