Abstract
A piston for an internal combustion engine may include a plurality of pin bores for accommodating a piston pin. The pin bores may be transversely oval to a longitudinal axis of the piston. The pin bores may be formed in a circular cylindrical manner at a zenith of α=0° and at a nadir of α=180°. The pin bores may be formed in an oval manner with an oil-holding volume at an equator of α=90° and α=270°. The pin bores may include a transition between the equator and the zenith and between the equator and the nadir that runs in a continuous and differentiable manner.
