Abstract

A piston of an internal combustion engine is disclosed. The piston may have a piston sleeve with a centre axis and a piston base with a diameter D delimiting the piston sleeve at a top of the piston sleeve. The piston base may have a piston base rim of width b and a piston bowl with a depth t. The piston bowl may be designed as a pot bowl, which may have a piston bowl base and a piston bowl wall with a maximum diameter d4 adjoining the piston bowl base. The piston bowl may have an opening cross-section aligned symmetrically relative to the centre axis. The opening cross-section may have a minimum diameter da, which is smaller than the diameter d4. A flow cut-off edge designed as a nose may be formed in the opening cross-section and may project in the radial direction inwards over the piston bowl wall.
