Abstract:
A piston for an internal combustion engine includes a piston bowl. The piston bowl has a half section profile that includes a bowl entry extending radially from the longitudinal piston center axis, a first bowl recess extending radially from the bowl entry and defining a bowl depth and a first radius of curvature, a second bowl recess extending radially from a first bowl recess to an end perimeter surface and defining a second radius of curvature, a bowl lip defined by the first bowl recess and the second bowl recess, and a bowl edge defined by the second bowl recess and the end perimeter surface. The first bowl recess further defines a first bowl recess exit angle at the bowl lip. The second bowl recess further defines a second bowl recess exit angle at the bowl edge.
