Piston of an internal combustion engine

An internal combustion engine, comprising:

• at least one piston including:
• a piston head including a piston bowl, a ring part and an annular cooling channel arranged between the ring part and the piston bowl;
• a closure element structured and arranged to close the cooling channel in a direction away from the piston bowl;
• and
• at least one guiding element arranged in the cooling channel, the at least one guiding element providing a lug facing in a direction of an inner cooling channel wall and disposed at least partially circumferentially, wherein the lug of the at least one guiding element is structured and arranged to direct cooling oil present in the cooling channel towards an upper region of the inner cooling channel wall relative to the closure element to facilitate cooling the upper region;
• wherein the at least one guiding element has a lower flange extending radially and circumferentially around the at least one guiding element, the lower flange being clamped and held between an underside of the ring part and the closure element.
