Abstract
Disclosed is a piston () that is capable of not only suppressing the occurrence of knocking but also reducing cooling loss in an internal combustion engine in which a tumble flow is formed in a cylinder. The piston for the internal combustion engine in which the tumble flow is formed in the cylinder includes a non-adiabatic region () that is a region on a piston upper surface () brought into contact with the tumble flow during an intake stroke and has no insulating layer. The piston also includes an adiabatic region () that is a region on at least a part of the piston upper surface excluding the non-adiabatic region and has an insulating layer.
