Piston with combustion stabilizing bowl

A piston configured to reciprocate in a bore of an engine, the piston comprising:

• an annular body including a combustion bowl defining a volume and surrounded on a top side thereof by an annular crown portion defining a top squish surface with an inner edge defining an opening to the combustion bowl, the opening having an area for combustion gases to enter the bowl during a compression stroke of the piston, wherein the combustion bowl comprises a reentrant surface that extends axially downwardly and radially outwardly relative to the top squish surface and defines a tangent that forms a reentrant angle with the top squish surface that ranges from 28.0 degrees to 32.0 degrees;
• the combustion bowl further including a concave arcuate surface extending from the reentrant surface, a converging surface extending radially inward from the concave arcuate surface, a transition surface extending from the converging surface, a bottom extremity defining surface, and a cylindrical surface extending axially upwardly from the bottom extremity defining surface;
• and
• a minimum diameter of the combustion bowl, axially below the opening to the combustion bowl, is defined by the cylindrical surface.
