A piston includes a piston body having an outer cylindrical surface and defined along a longitudinal piston center axis. The piston further includes a piston bowl with a half section profile with a bowl entry extending radially from the longitudinal piston center axis; a bowl recess extending radially from the bowl entry; and a soot shelf extending from the bowl recess to define a soot shelf axial height (H) and a soot shelf radial width (W). The soot shelf includes an inner step being formed by an inner step base surface extending radially from the bowl recess; an outer step being formed by a step shoulder surface extending axially from the inner step base surface and an outer step base surface extending radially from the step shoulder surface; and a soot shelf shoulder surface extending axially from outer step base surface to the end perimeter surface.
