Abstract
A piston is disclosed. The piston may have a piston crown having a top surface. The piston may also have a first land disposed in the piston crown adjacent the top surface. The first land may have a side surface disposed generally orthogonal to the top surface. Further the piston may have a second land axially separated from the first land. In addition, the piston may have a groove disposed between the first land and the second land. The piston may also have a notch extending between the side surface and the top surface. The notch may have a generally concave shape and may extend circumferentially around the top surface.
