Beschreibung
Zusammenfassung:	A piston includes a crown having a deck, a spark recess, an exhaust valve recess, and an intake valve recess. The piston also includes a wedge disposed on the crown extending from the exhaust valve recess and the intake valve recess toward the spark recess above the deck. The wedge is a planar wedge disposed at an angle substantially parallel to an associated exhaust valve received by the exhaust valve recess. The crown is symmetrical about a piston center line.
