Abstract
A piston for an engine may include a piston crown, and a piston bowl recessed within the piston crown. The piston bowl includes a center portion, a cone portion, and an annular toroidal portion. The geometry of the piston bowl is designed to correspond with a fuel injection nozzle having a specific spray angle. An exemplary piston bowl may include a toroidal major diameter between about 4.645 and 4.895 inches and a toroidal minor radius between about 1.165 and 1.235 inches. The cone portion includes an angle between about 26 to 34 degrees. The compression ratio of the piston is about 17.95 to 1.
