ABSTRACT:
A piston for internal combustion engines, especially for high-performance internal combustion engines. The piston has several ring grooves for piston rings, and an oil control groove which is provided below the top ring groove, is separated therefrom, and opens only towards the cylinder bore. The land between the topmost ring groove and the oil control groove, seen in cross section, is designed as a support having constant bending stress and has a finite height at its outer surface. The inner confine of the oil control groove has a finite radius or rounded-off section to avoid an increased stress concentration factor.
