A piston for engine may include 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 include an inner edge defining an opening to the combustion bowl. The opening may include an area for combustion gases to enter the bowl during a compression stroke of the piston. The combustion bowl may include a reentrant surface that defines a tangent that forms a reentrant angle with the top squish surface. The reentrant angle may range from 28.0 degrees to 32.0 degrees. A ratio of a bowl volume to an area of the entry opening may ranges from 45 mm to 52 mm. A ratio of a bowl volume to the reentrant angle may range from 12 cc/deg to 15 cc/deg.
