Abstract
A piston for an internal combustion engine includes a piston skirt and a piston crown attached to the piston skirt and including a combustion face. The combustion face forms a piston rim and a combustion bowl. A bowl edge defines an intersection of the combustion bowl and the piston rim, and a reentrant surface defining a reentrancy angle extends between the bowl edge and a bowl outer wall. A ratio of a bowl depth dimension coincident with the piston center axis to a compression height dimension coincident with the piston center axis is from about 0.30 to about 0.35.
