Abstract

See full text

A piston of an internal combustion engine includes a piston head including a ring belt having a firing land and a plurality of ring grooves for receiving piston rings. A first ring groove of the plurality of ring grooves that is arranged directly adjacent to the firing land has a ring groove axis that runs coaxially to a piston axis of the piston. The first ring groove has an upper groove flank and a lower groove flank arranged away from the firing land relative to the upper groove flank. At least the lower groove flank of at least the first ring groove is inclined by an inclination angle with respect to an orthogonal plane relative to the piston axis, and the inclination angle of at least the lower groove flank varies in a circumferential direction of the piston axis.
