Abstract
A piston for an engine may include a piston body. The piston body may include a piston crown disposed symmetrically about a central longitudinal axis of the piston. A combustion bowl may be recessed into the piston body and may be offset axially inwardly with respect to the piston crown. A central bowl apex may protrude axially from the combustion bowl and may be offset axially inwardly with respect to the piston crown. A first bowl apex may protrude axially from the combustion bowl and may be disposed radially inwardly with respect to the piston crown. A second bowl apex may protrude axially from the combustion bowl and may be disposed radially inwardly with respect to the first bowl apex and may be radially between the first bowl apex and the central bowl apex. The second bowl apex may be offset axially inwardly with respect to the central bowl apex.
